 8 | # Creating Lights
 9 | 
10 | All of Extra Light's presets can be found in the 3D View's Add menu. 
11 | 
12 | If you purchased the Blender Market version, you'll also have an asset browser ready file with each of the lights marked as assets. Using the asset version may be preferred in some situations, but you won't be able to adjust each light using Lumens after creation. 
13 | 
14 | When you add a light with Extra Lights, you'll have the option to adjust its parameters via Blender's redo panel (F9). 
15 | 
16 | ## Lumens
17 | 
18 | This is how bright the light is as measured in Lumens. Blender's lights need to be set in Watts, and the add-on will do the conversion for you. 
19 | 
20 | ## Set Color With
21 | 
22 | Here, you can choose to either set a Kelvin color temperature or a RGB color. Regardless of which one you choose, the light's strength in watts will be adjusted based on the color's luminous efficacy, so that the total number of lumens and its perceptual brightness will remain the same. 
23 | 
24 | ## Use Nodes
25 | 
26 | Use Nodes is great to have enabled if you're using Cycles, because it adds a lumens conversion node to the light which allows you to change the lumens and color after creation. Since Eevee lights cannot use nodes, this option does not work in Eevee, and the only opportunity to change the brightness and color with lumens is during creation. 
27 | 
28 | ## Set Exposure
29 | 
30 | Some lights may be far too dim or bright for Blender's default exposure. Checking Set Exposure will automatically adjust the scene's exposure to match the brightness of the newly added light. 
31 | 
32 | This will also adjust the Light Threshold, which is the minimum amount of light that is detected while rendering. If the Light threshold is not set while using a very dim light, even with the exposure set very high, the result will be unrealistically dim and/or extremely noisy. It is always recommended that you use this option when working with dim lights such as candles or moonlight. 
33 | 
34 | ## Create Linked Sky
35 | 
36 | When adding a sun type light, you'll have an additional option to create a new world sky texture that's linked to the rotation of the new sun.

 1 | # About Extra Lights
 2 | 
 3 | Extra Lights is an add-on for Blender that adds physically based, photometric light presets to the 3D View Add menu. All lights have their strength and colors based on real world light fixtures and are organized by type and strength.
 4 | 
 5 | **[Watch the Extra Lights video tutorial](https://youtu.be/ipqyVWm5JmY)**
 6 | 
 7 | **[You can purchase Extra Lights, which comes with 60+ presets, from the Blender Market.](https://blendermarket.com/products/extra-lights)** It is installed the same as any other Blender add-on. 
 8 | 
 9 | ## Blender's defaults are made to be mathematically convenient, not artistically intuitive.
10 | 
11 | The default cube is a whopping 6.5 feet tall (2 m), the camera is flying 16 feet (5 m) off the ground, and the default lamp is about 20 feet (5.8 m) from the nearest point on the cube. 
12 | 
13 | Why does this matter? Because the apparent scale of your scene and the strength of your lights are interconnected. 
14 | 
15 | Light follows the inverse square law when it’s being emitted in all directions, which states that the amount of light hitting a surface decreases in proportion with the square of its distance from the source. It's a very specific curve that our eyes are used to seeing. If we scale up a room five times, one way we can tell that it’s bigger is by observing the falloff of the light. 
16 | 
17 | You can imagine that if we’re just guessing about how bright to set the light, we can very easily make something look too large or too small totally by accident. It’s not something we’d notice right away but it can subconsciously tip us off to the fact that something is faked. 
18 | 
19 | If you use real world measurements for the scale of your models, then using real world measurements for your lights will give you more natural looking results. However, that's easier said than done. 
20 | 
21 | ## Wrong watts, Watson!
22 | 
23 | Blender’s lights are calculated in watts. A bulb in my lamp at home says 45 watts, so if I set my Blender light to be 45 watts and the same size then it should match, right? Unfortunately, we’d be way off because there are two different measurements going on and both use watts as a unit. 
24 | 
25 | A lightbulb is listing the amount of electrical watts needed to power it on, while Blender is calculating how many watts are being emitted as light. Since an incandescent light bulb is not that efficient, only a fraction of the input watts are turning into visible light while the rest is turning into heat. 
26 | 
27 | To make things more confusing, other types of bulbs, like very efficient LEDs, sometimes show a watt equivalent, which is how much energy it would hypothetically use if it were an incandescent bulb of similar brightness, which is neither how much it is using nor how much it’s putting out. Good grief. 
28 | 
29 | ## Lighting with lumens
30 | 
31 | What most lights are measured in, however, is lumens. Lumens measure how much light appears to the human eye as being emitted from the source. It's a believably consistent way of lighting that uses information we can easily find online. 
32 | 
33 | Here’s where things get a little weird. As mentioned, lumens are based on how bright something appears to the human eye to be. We can’t do a simple conversion because different RGB hues of the same value appear to us as different brightnesses. If you’ve ever run into the frustration of trying to make something really colorful but also really really bright, or even consistently bright between colors, I feel your pain. The problem isn’t with the computer or physics though, it’s with our eyeballs. 
34 | 
35 | We’re just better at detecting some wavelengths of light than others, so in order to convert lumens to watts in an RGB system we need to first get the spectral distribution of the light, separate the red, green, and blue, multiply by the luminous efficacy of each, multiply by the maximum possible efficacy, add them back together, and use that to divide the input number of lumens by in order to get the corrects watts output. 
36 | 
37 | That's a lot to worry about though, so this addon does it all for you! 
38 | 
39 | ## Keeping it cool (or warm) with Kelvin
40 | 
41 | Creating believable lights isn't just about the strength - it's also about the color! 
42 | 
43 | To measure naturally produced light, we use a Kelvin value, which is what color a completely neutral substance (called a blackbody) is when heated to that Kelvin temperature. 
44 | 
45 | A candle starts at around 1800, incandescent bulbs are usually around 2700, fluorescent light is around 3-4000-ish, direct sun is around 5000 give or take, and a clear sky can be about 6500. By coloring your lights using Kelvin values, they’ll be a bit more believable, especially when you have more than one type of light in your scene that you’ll be comparing them with.
46 | 
47 | All of the lights in this addon have their color temperatures set in Kelvin based on their real world sources so that you don't have to remember all that. 
48 | 
49 | ## 60+ physically based lights
50 | 
51 | The lights are organized into four categories - natural, incandescent, LED, and fluorescent. To keep things simple I've placed halogen lights under incandescent and metal halide & high intensity discharge lights under fluorescent. They're not technically the same, but for artistic uses they're close enough. 
52 | 
53 | Note - since EEVEE doesn't support nodes, IES lights will only show their texture in Cycles
54 | 
55 | ## Simply better defaults, that's all
56 | 
57 | Although I'm basing these values off of the best information I can find from the real word, the end result is not going to be exactly perfect because I've had to make some assumptions. 
58 | 
59 | The lumen and Kelvin values listed by light manufacturers are enough to at least get us in the right ballpark, but we don’t have enough information about how they got those numbers in order to exactly match reality. So, I can call these lights physically based or photorealistic, because they are, but I’m not going to claim that they are physically accurate because that’s just not possible with the kind of data that’s readily available. We could actually get more accurate results by using radiant watts, but that's less easy for the user to look up and can be confusing as explained above. 
60 | 
61 | Secondly, do you have to use real world values to light your scene, even if they could be 100% accurate? NO! If computer graphics isn’t about bending the laws of physics to your whim to make s**t look cool, then I don’t know what is. Reality doesn’t always live up to our ridiculous expectations, which is why film studios and photographers use absurdly bright lights and more visual trickery than a stage magician. However, it’s better to start with something based in reality and break rules of thumb intentionally when you want to be creative, rather than by accident and the other way around.

 21 | software for all its users.  We, the Free Software Foundation, use the
 22 | GNU General Public License for most of our software; it applies also to
 23 | any other work released this way by its authors.  You can apply it to
 24 | your programs, too.
 25 | 
 26 |   When we speak of free software, we are referring to freedom, not
 27 | price.  Our General Public Licenses are designed to make sure that you
 28 | have the freedom to distribute copies of free software (and charge for
 29 | them if you wish), that you receive source code or can get it if you
 30 | want it, that you can change the software or use pieces of it in new

 32 | 
 33 |   To protect your rights, we need to prevent others from denying you
 34 | these rights or asking you to surrender the rights.  Therefore, you have
 35 | certain responsibilities if you distribute copies of the software, or if
 36 | you modify it: responsibilities to respect the freedom of others.
 37 | 
 38 |   For example, if you distribute copies of such a program, whether
 39 | gratis or for a fee, you must pass on to the recipients the same
 40 | freedoms that you received.  You must make sure that they, too, receive
 41 | or can get the source code.  And you must show them these terms so they
 42 | know their rights.
 43 | 
 44 |   Developers that use the GNU GPL protect your rights with two steps:
 45 | (1) assert copyright on the software, and (2) offer you this License
 46 | giving you legal permission to copy, distribute and/or modify it.
 47 | 
 48 |   For the developers' and authors' protection, the GPL clearly explains
 49 | that there is no warranty for this free software.  For both users' and
 50 | authors' sake, the GPL requires that modified versions be marked as
 51 | changed, so that their problems will not be attributed erroneously to
 52 | authors of previous versions.
 53 | 
 54 |   Some devices are designed to deny users access to install or run
 55 | modified versions of the software inside them, although the manufacturer
 56 | can do so.  This is fundamentally incompatible with the aim of
 57 | protecting users' freedom to change the software.  The systematic
 58 | pattern of such abuse occurs in the area of products for individuals to
 59 | use, which is precisely where it is most unacceptable.  Therefore, we
 60 | have designed this version of the GPL to prohibit the practice for those
 61 | products.  If such problems arise substantially in other domains, we
 62 | stand ready to extend this provision to those domains in future versions
 63 | of the GPL, as needed to protect the freedom of users.
 64 | 
 65 |   Finally, every program is threatened constantly by software patents.
 66 | States should not allow patents to restrict development and use of
 67 | software on general-purpose computers, but in those that do, we wish to
 68 | avoid the special danger that patents applied to a free program could
 69 | make it effectively proprietary.  To prevent this, the GPL assures that
 70 | patents cannot be used to render the program non-free.
 71 | 
 72 |   The precise terms and conditions for copying, distribution and
 73 | modification follow.
 74 | 
 75 |                        TERMS AND CONDITIONS
 76 | 
 77 |   0. Definitions.
 78 | 
 79 |   "This License" refers to version 3 of the GNU General Public License.
 80 | 
 81 |   "Copyright" also means copyright-like laws that apply to other kinds of
 82 | works, such as semiconductor masks.
 83 | 
 84 |   "The Program" refers to any copyrightable work licensed under this
 85 | License.  Each licensee is addressed as "you".  "Licensees" and
 86 | "recipients" may be individuals or organizations.
 87 | 
 88 |   To "modify" a work means to copy from or adapt all or part of the work
 89 | in a fashion requiring copyright permission, other than the making of an
 90 | exact copy.  The resulting work is called a "modified version" of the
 91 | earlier work or a work "based on" the earlier work.
 92 | 
 93 |   A "covered work" means either the unmodified Program or a work based
 94 | on the Program.
 95 | 
 96 |   To "propagate" a work means to do anything with it that, without
 97 | permission, would make you directly or secondarily liable for
 98 | infringement under applicable copyright law, except executing it on a
 99 | computer or modifying a private copy.  Propagation includes copying,
100 | distribution (with or without modification), making available to the
101 | public, and in some countries other activities as well.
102 | 
103 |   To "convey" a work means any kind of propagation that enables other
104 | parties to make or receive copies.  Mere interaction with a user through
105 | a computer network, with no transfer of a copy, is not conveying.
106 | 
107 |   An interactive user interface displays "Appropriate Legal Notices"
108 | to the extent that it includes a convenient and prominently visible
109 | feature that (1) displays an appropriate copyright notice, and (2)
110 | tells the user that there is no warranty for the work (except to the
111 | extent that warranties are provided), that licensees may convey the
112 | work under this License, and how to view a copy of this License.  If
113 | the interface presents a list of user commands or options, such as a
114 | menu, a prominent item in the list meets this criterion.
115 | 
116 |   1. Source Code.
117 | 
118 |   The "source code" for a work means the preferred form of the work
119 | for making modifications to it.  "Object code" means any non-source
120 | form of a work.
121 | 
122 |   A "Standard Interface" means an interface that either is an official
123 | standard defined by a recognized standards body, or, in the case of
124 | interfaces specified for a particular programming language, one that
125 | is widely used among developers working in that language.
126 | 
127 |   The "System Libraries" of an executable work include anything, other
128 | than the work as a whole, that (a) is included in the normal form of
129 | packaging a Major Component, but which is not part of that Major
130 | Component, and (b) serves only to enable use of the work with that
131 | Major Component, or to implement a Standard Interface for which an
132 | implementation is available to the public in source code form.  A
133 | "Major Component", in this context, means a major essential component
134 | (kernel, window system, and so on) of the specific operating system
135 | (if any) on which the executable work runs, or a compiler used to
136 | produce the work, or an object code interpreter used to run it.
137 | 
138 |   The "Corresponding Source" for a work in object code form means all
139 | the source code needed to generate, install, and (for an executable
140 | work) run the object code and to modify the work, including scripts to
141 | control those activities.  However, it does not include the work's
142 | System Libraries, or general-purpose tools or generally available free
143 | programs which are used unmodified in performing those activities but
144 | which are not part of the work.  For example, Corresponding Source
145 | includes interface definition files associated with source files for
146 | the work, and the source code for shared libraries and dynamically
147 | linked subprograms that the work is specifically designed to require,
148 | such as by intimate data communication or control flow between those
149 | subprograms and other parts of the work.
150 | 
151 |   The Corresponding Source need not include anything that users
152 | can regenerate automatically from other parts of the Corresponding
153 | Source.
154 | 
155 |   The Corresponding Source for a work in source code form is that
156 | same work.
157 | 
158 |   2. Basic Permissions.
159 | 
160 |   All rights granted under this License are granted for the term of
161 | copyright on the Program, and are irrevocable provided the stated
162 | conditions are met.  This License explicitly affirms your unlimited
163 | permission to run the unmodified Program.  The output from running a
164 | covered work is covered by this License only if the output, given its
165 | content, constitutes a covered work.  This License acknowledges your
166 | rights of fair use or other equivalent, as provided by copyright law.
167 | 
168 |   You may make, run and propagate covered works that you do not
169 | convey, without conditions so long as your license otherwise remains
170 | in force.  You may convey covered works to others for the sole purpose
171 | of having them make modifications exclusively for you, or provide you
172 | with facilities for running those works, provided that you comply with
173 | the terms of this License in conveying all material for which you do
174 | not control copyright.  Those thus making or running the covered works
175 | for you must do so exclusively on your behalf, under your direction
176 | and control, on terms that prohibit them from making any copies of
177 | your copyrighted material outside their relationship with you.
178 | 
179 |   Conveying under any other circumstances is permitted solely under
180 | the conditions stated below.  Sublicensing is not allowed; section 10
181 | makes it unnecessary.
182 | 
183 |   3. Protecting Users' Legal Rights From Anti-Circumvention Law.
184 | 
185 |   No covered work shall be deemed part of an effective technological
186 | measure under any applicable law fulfilling obligations under article
187 | 11 of the WIPO copyright treaty adopted on 20 December 1996, or
188 | similar laws prohibiting or restricting circumvention of such
189 | measures.
190 | 
191 |   When you convey a covered work, you waive any legal power to forbid
192 | circumvention of technological measures to the extent such circumvention
193 | is effected by exercising rights under this License with respect to
194 | the covered work, and you disclaim any intention to limit operation or
195 | modification of the work as a means of enforcing, against the work's
196 | users, your or third parties' legal rights to forbid circumvention of
197 | technological measures.
198 | 
199 |   4. Conveying Verbatim Copies.
200 | 
201 |   You may convey verbatim copies of the Program's source code as you
202 | receive it, in any medium, provided that you conspicuously and
203 | appropriately publish on each copy an appropriate copyright notice;
204 | keep intact all notices stating that this License and any
205 | non-permissive terms added in accord with section 7 apply to the code;
206 | keep intact all notices of the absence of any warranty; and give all
207 | recipients a copy of this License along with the Program.
208 | 
209 |   You may charge any price or no price for each copy that you convey,
210 | and you may offer support or warranty protection for a fee.
211 | 
212 |   5. Conveying Modified Source Versions.
213 | 
214 |   You may convey a work based on the Program, or the modifications to
215 | produce it from the Program, in the form of source code under the
216 | terms of section 4, provided that you also meet all of these conditions:
217 | 
218 |     a) The work must carry prominent notices stating that you modified
219 |     it, and giving a relevant date.
220 | 
221 |     b) The work must carry prominent notices stating that it is
222 |     released under this License and any conditions added under section
223 |     7.  This requirement modifies the requirement in section 4 to
224 |     "keep intact all notices".
225 | 
226 |     c) You must license the entire work, as a whole, under this
227 |     License to anyone who comes into possession of a copy.  This
228 |     License will therefore apply, along with any applicable section 7
229 |     additional terms, to the whole of the work, and all its parts,
230 |     regardless of how they are packaged.  This License gives no
231 |     permission to license the work in any other way, but it does not
232 |     invalidate such permission if you have separately received it.
233 | 
234 |     d) If the work has interactive user interfaces, each must display
235 |     Appropriate Legal Notices; however, if the Program has interactive
236 |     interfaces that do not display Appropriate Legal Notices, your
237 |     work need not make them do so.
238 | 
239 |   A compilation of a covered work with other separate and independent
240 | works, which are not by their nature extensions of the covered work,
241 | and which are not combined with it such as to form a larger program,
242 | in or on a volume of a storage or distribution medium, is called an
243 | "aggregate" if the compilation and its resulting copyright are not
244 | used to limit the access or legal rights of the compilation's users
245 | beyond what the individual works permit.  Inclusion of a covered work
246 | in an aggregate does not cause this License to apply to the other
247 | parts of the aggregate.
248 | 
249 |   6. Conveying Non-Source Forms.
250 | 
251 |   You may convey a covered work in object code form under the terms
252 | of sections 4 and 5, provided that you also convey the
253 | machine-readable Corresponding Source under the terms of this License,
254 | in one of these ways:
255 | 
256 |     a) Convey the object code in, or embodied in, a physical product
257 |     (including a physical distribution medium), accompanied by the
258 |     Corresponding Source fixed on a durable physical medium
259 |     customarily used for software interchange.
260 | 
261 |     b) Convey the object code in, or embodied in, a physical product
262 |     (including a physical distribution medium), accompanied by a
263 |     written offer, valid for at least three years and valid for as
264 |     long as you offer spare parts or customer support for that product
265 |     model, to give anyone who possesses the object code either (1) a
266 |     copy of the Corresponding Source for all the software in the
267 |     product that is covered by this License, on a durable physical
268 |     medium customarily used for software interchange, for a price no
269 |     more than your reasonable cost of physically performing this
270 |     conveying of source, or (2) access to copy the
271 |     Corresponding Source from a network server at no charge.
272 | 
273 |     c) Convey individual copies of the object code with a copy of the
274 |     written offer to provide the Corresponding Source.  This
275 |     alternative is allowed only occasionally and noncommercially, and
276 |     only if you received the object code with such an offer, in accord
277 |     with subsection 6b.
278 | 
279 |     d) Convey the object code by offering access from a designated
280 |     place (gratis or for a charge), and offer equivalent access to the
281 |     Corresponding Source in the same way through the same place at no
282 |     further charge.  You need not require recipients to copy the
283 |     Corresponding Source along with the object code.  If the place to
284 |     copy the object code is a network server, the Corresponding Source
285 |     may be on a different server (operated by you or a third party)
286 |     that supports equivalent copying facilities, provided you maintain
287 |     clear directions next to the object code saying where to find the
288 |     Corresponding Source.  Regardless of what server hosts the
289 |     Corresponding Source, you remain obligated to ensure that it is
290 |     available for as long as needed to satisfy these requirements.
291 | 
292 |     e) Convey the object code using peer-to-peer transmission, provided
293 |     you inform other peers where the object code and Corresponding
294 |     Source of the work are being offered to the general public at no
295 |     charge under subsection 6d.
296 | 
297 |   A separable portion of the object code, whose source code is excluded
298 | from the Corresponding Source as a System Library, need not be
299 | included in conveying the object code work.
300 | 
301 |   A "User Product" is either (1) a "consumer product", which means any
302 | tangible personal property which is normally used for personal, family,
303 | or household purposes, or (2) anything designed or sold for incorporation
304 | into a dwelling.  In determining whether a product is a consumer product,
305 | doubtful cases shall be resolved in favor of coverage.  For a particular
306 | product received by a particular user, "normally used" refers to a
307 | typical or common use of that class of product, regardless of the status
308 | of the particular user or of the way in which the particular user
309 | actually uses, or expects or is expected to use, the product.  A product
310 | is a consumer product regardless of whether the product has substantial
311 | commercial, industrial or non-consumer uses, unless such uses represent
312 | the only significant mode of use of the product.
313 | 
314 |   "Installation Information" for a User Product means any methods,
315 | procedures, authorization keys, or other information required to install
316 | and execute modified versions of a covered work in that User Product from
317 | a modified version of its Corresponding Source.  The information must
318 | suffice to ensure that the continued functioning of the modified object
319 | code is in no case prevented or interfered with solely because
320 | modification has been made.
321 | 
322 |   If you convey an object code work under this section in, or with, or
323 | specifically for use in, a User Product, and the conveying occurs as
324 | part of a transaction in which the right of possession and use of the
325 | User Product is transferred to the recipient in perpetuity or for a
326 | fixed term (regardless of how the transaction is characterized), the
327 | Corresponding Source conveyed under this section must be accompanied
328 | by the Installation Information.  But this requirement does not apply
329 | if neither you nor any third party retains the ability to install
330 | modified object code on the User Product (for example, the work has
331 | been installed in ROM).
332 | 
333 |   The requirement to provide Installation Information does not include a
334 | requirement to continue to provide support service, warranty, or updates
335 | for a work that has been modified or installed by the recipient, or for
336 | the User Product in which it has been modified or installed.  Access to a
337 | network may be denied when the modification itself materially and
338 | adversely affects the operation of the network or violates the rules and
339 | protocols for communication across the network.
340 | 
341 |   Corresponding Source conveyed, and Installation Information provided,
342 | in accord with this section must be in a format that is publicly
343 | documented (and with an implementation available to the public in
344 | source code form), and must require no special password or key for
345 | unpacking, reading or copying.
346 | 
347 |   7. Additional Terms.
348 | 
349 |   "Additional permissions" are terms that supplement the terms of this
350 | License by making exceptions from one or more of its conditions.
351 | Additional permissions that are applicable to the entire Program shall
352 | be treated as though they were included in this License, to the extent
353 | that they are valid under applicable law.  If additional permissions
354 | apply only to part of the Program, that part may be used separately
355 | under those permissions, but the entire Program remains governed by
356 | this License without regard to the additional permissions.
357 | 
358 |   When you convey a copy of a covered work, you may at your option
359 | remove any additional permissions from that copy, or from any part of
360 | it.  (Additional permissions may be written to require their own
361 | removal in certain cases when you modify the work.)  You may place
362 | additional permissions on material, added by you to a covered work,
363 | for which you have or can give appropriate copyright permission.
364 | 
365 |   Notwithstanding any other provision of this License, for material you
366 | add to a covered work, you may (if authorized by the copyright holders of
367 | that material) supplement the terms of this License with terms:
368 | 
369 |     a) Disclaiming warranty or limiting liability differently from the
370 |     terms of sections 15 and 16 of this License; or
371 | 
372 |     b) Requiring preservation of specified reasonable legal notices or
373 |     author attributions in that material or in the Appropriate Legal
374 |     Notices displayed by works containing it; or
375 | 
376 |     c) Prohibiting misrepresentation of the origin of that material, or
377 |     requiring that modified versions of such material be marked in
378 |     reasonable ways as different from the original version; or
379 | 
380 |     d) Limiting the use for publicity purposes of names of licensors or
381 |     authors of the material; or
382 | 
383 |     e) Declining to grant rights under trademark law for use of some
384 |     trade names, trademarks, or service marks; or
385 | 
386 |     f) Requiring indemnification of licensors and authors of that
387 |     material by anyone who conveys the material (or modified versions of
388 |     it) with contractual assumptions of liability to the recipient, for
389 |     any liability that these contractual assumptions directly impose on
390 |     those licensors and authors.
391 | 
392 |   All other non-permissive additional terms are considered "further
393 | restrictions" within the meaning of section 10.  If the Program as you
394 | received it, or any part of it, contains a notice stating that it is
395 | governed by this License along with a term that is a further
396 | restriction, you may remove that term.  If a license document contains
397 | a further restriction but permits relicensing or conveying under this
398 | License, you may add to a covered work material governed by the terms
399 | of that license document, provided that the further restriction does
400 | not survive such relicensing or conveying.
401 | 
402 |   If you add terms to a covered work in accord with this section, you
403 | must place, in the relevant source files, a statement of the
404 | additional terms that apply to those files, or a notice indicating
405 | where to find the applicable terms.
406 | 
407 |   Additional terms, permissive or non-permissive, may be stated in the
408 | form of a separately written license, or stated as exceptions;
409 | the above requirements apply either way.
410 | 
411 |   8. Termination.
412 | 
413 |   You may not propagate or modify a covered work except as expressly
414 | provided under this License.  Any attempt otherwise to propagate or
415 | modify it is void, and will automatically terminate your rights under
416 | this License (including any patent licenses granted under the third
417 | paragraph of section 11).
418 | 
419 |   However, if you cease all violation of this License, then your
420 | license from a particular copyright holder is reinstated (a)
421 | provisionally, unless and until the copyright holder explicitly and
422 | finally terminates your license, and (b) permanently, if the copyright
423 | holder fails to notify you of the violation by some reasonable means
424 | prior to 60 days after the cessation.
425 | 
426 |   Moreover, your license from a particular copyright holder is
427 | reinstated permanently if the copyright holder notifies you of the
428 | violation by some reasonable means, this is the first time you have
429 | received notice of violation of this License (for any work) from that
430 | copyright holder, and you cure the violation prior to 30 days after
431 | your receipt of the notice.
432 | 
433 |   Termination of your rights under this section does not terminate the
434 | licenses of parties who have received copies or rights from you under
435 | this License.  If your rights have been terminated and not permanently
436 | reinstated, you do not qualify to receive new licenses for the same
437 | material under section 10.
438 | 
439 |   9. Acceptance Not Required for Having Copies.
440 | 
441 |   You are not required to accept this License in order to receive or
442 | run a copy of the Program.  Ancillary propagation of a covered work
443 | occurring solely as a consequence of using peer-to-peer transmission
444 | to receive a copy likewise does not require acceptance.  However,
445 | nothing other than this License grants you permission to propagate or
446 | modify any covered work.  These actions infringe copyright if you do
447 | not accept this License.  Therefore, by modifying or propagating a
448 | covered work, you indicate your acceptance of this License to do so.
449 | 
450 |   10. Automatic Licensing of Downstream Recipients.
451 | 
452 |   Each time you convey a covered work, the recipient automatically
453 | receives a license from the original licensors, to run, modify and
454 | propagate that work, subject to this License.  You are not responsible
455 | for enforcing compliance by third parties with this License.
456 | 
457 |   An "entity transaction" is a transaction transferring control of an
458 | organization, or substantially all assets of one, or subdividing an
459 | organization, or merging organizations.  If propagation of a covered
460 | work results from an entity transaction, each party to that
461 | transaction who receives a copy of the work also receives whatever
462 | licenses to the work the party's predecessor in interest had or could
463 | give under the previous paragraph, plus a right to possession of the
464 | Corresponding Source of the work from the predecessor in interest, if
465 | the predecessor has it or can get it with reasonable efforts.
466 | 
467 |   You may not impose any further restrictions on the exercise of the
468 | rights granted or affirmed under this License.  For example, you may
469 | not impose a license fee, royalty, or other charge for exercise of
470 | rights granted under this License, and you may not initiate litigation
471 | (including a cross-claim or counterclaim in a lawsuit) alleging that
472 | any patent claim is infringed by making, using, selling, offering for
473 | sale, or importing the Program or any portion of it.
474 | 
475 |   11. Patents.
476 | 
477 |   A "contributor" is a copyright holder who authorizes use under this
478 | License of the Program or a work on which the Program is based.  The
479 | work thus licensed is called the contributor's "contributor version".
480 | 
481 |   A contributor's "essential patent claims" are all patent claims
482 | owned or controlled by the contributor, whether already acquired or
483 | hereafter acquired, that would be infringed by some manner, permitted
484 | by this License, of making, using, or selling its contributor version,
485 | but do not include claims that would be infringed only as a
486 | consequence of further modification of the contributor version.  For
487 | purposes of this definition, "control" includes the right to grant
488 | patent sublicenses in a manner consistent with the requirements of
489 | this License.
490 | 
491 |   Each contributor grants you a non-exclusive, worldwide, royalty-free
492 | patent license under the contributor's essential patent claims, to
493 | make, use, sell, offer for sale, import and otherwise run, modify and
494 | propagate the contents of its contributor version.
495 | 
496 |   In the following three paragraphs, a "patent license" is any express
497 | agreement or commitment, however denominated, not to enforce a patent
498 | (such as an express permission to practice a patent or covenant not to
499 | sue for patent infringement).  To "grant" such a patent license to a
500 | party means to make such an agreement or commitment not to enforce a
501 | patent against the party.
502 | 
503 |   If you convey a covered work, knowingly relying on a patent license,
504 | and the Corresponding Source of the work is not available for anyone
505 | to copy, free of charge and under the terms of this License, through a
506 | publicly available network server or other readily accessible means,
507 | then you must either (1) cause the Corresponding Source to be so
508 | available, or (2) arrange to deprive yourself of the benefit of the
509 | patent license for this particular work, or (3) arrange, in a manner
510 | consistent with the requirements of this License, to extend the patent
511 | license to downstream recipients.  "Knowingly relying" means you have
512 | actual knowledge that, but for the patent license, your conveying the
513 | covered work in a country, or your recipient's use of the covered work
514 | in a country, would infringe one or more identifiable patents in that
515 | country that you have reason to believe are valid.
516 | 
517 |   If, pursuant to or in connection with a single transaction or
518 | arrangement, you convey, or propagate by procuring conveyance of, a
519 | covered work, and grant a patent license to some of the parties
520 | receiving the covered work authorizing them to use, propagate, modify
521 | or convey a specific copy of the covered work, then the patent license
522 | you grant is automatically extended to all recipients of the covered
523 | work and works based on it.
524 | 
525 |   A patent license is "discriminatory" if it does not include within
526 | the scope of its coverage, prohibits the exercise of, or is
527 | conditioned on the non-exercise of one or more of the rights that are
528 | specifically granted under this License.  You may not convey a covered
529 | work if you are a party to an arrangement with a third party that is
530 | in the business of distributing software, under which you make payment
531 | to the third party based on the extent of your activity of conveying
532 | the work, and under which the third party grants, to any of the
533 | parties who would receive the covered work from you, a discriminatory
534 | patent license (a) in connection with copies of the covered work
535 | conveyed by you (or copies made from those copies), or (b) primarily
536 | for and in connection with specific products or compilations that
537 | contain the covered work, unless you entered into that arrangement,
538 | or that patent license was granted, prior to 28 March 2007.
539 | 
540 |   Nothing in this License shall be construed as excluding or limiting
541 | any implied license or other defenses to infringement that may
542 | otherwise be available to you under applicable patent law.
543 | 
544 |   12. No Surrender of Others' Freedom.
545 | 
546 |   If conditions are imposed on you (whether by court order, agreement or
547 | otherwise) that contradict the conditions of this License, they do not
548 | excuse you from the conditions of this License.  If you cannot convey a
549 | covered work so as to satisfy simultaneously your obligations under this
550 | License and any other pertinent obligations, then as a consequence you may
551 | not convey it at all.  For example, if you agree to terms that obligate you
552 | to collect a royalty for further conveying from those to whom you convey
553 | the Program, the only way you could satisfy both those terms and this
554 | License would be to refrain entirely from conveying the Program.
555 | 
556 |   13. Use with the GNU Affero General Public License.
557 | 
558 |   Notwithstanding any other provision of this License, you have
559 | permission to link or combine any covered work with a work licensed
560 | under version 3 of the GNU Affero General Public License into a single
561 | combined work, and to convey the resulting work.  The terms of this
562 | License will continue to apply to the part which is the covered work,
563 | but the special requirements of the GNU Affero General Public License,
564 | section 13, concerning interaction through a network will apply to the
565 | combination as such.
566 | 
567 |   14. Revised Versions of this License.
568 | 
569 |   The Free Software Foundation may publish revised and/or new versions of
570 | the GNU General Public License from time to time.  Such new versions will
571 | be similar in spirit to the present version, but may differ in detail to
572 | address new problems or concerns.
573 | 
574 |   Each version is given a distinguishing version number.  If the
575 | Program specifies that a certain numbered version of the GNU General
576 | Public License "or any later version" applies to it, you have the
577 | option of following the terms and conditions either of that numbered
578 | version or of any later version published by the Free Software
579 | Foundation.  If the Program does not specify a version number of the
580 | GNU General Public License, you may choose any version ever published
581 | by the Free Software Foundation.
582 | 
583 |   If the Program specifies that a proxy can decide which future
584 | versions of the GNU General Public License can be used, that proxy's
585 | public statement of acceptance of a version permanently authorizes you
586 | to choose that version for the Program.
587 | 
588 |   Later license versions may give you additional or different
589 | permissions.  However, no additional obligations are imposed on any
590 | author or copyright holder as a result of your choosing to follow a
591 | later version.
592 | 
593 |   15. Disclaimer of Warranty.
594 | 
595 |   THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
596 | APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
597 | HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
598 | OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
599 | THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
600 | PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
601 | IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
602 | ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
603 | 
604 |   16. Limitation of Liability.
605 | 
606 |   IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
607 | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
608 | THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
609 | GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
610 | USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
611 | DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
612 | PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
613 | EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
614 | SUCH DAMAGES.
615 | 
616 |   17. Interpretation of Sections 15 and 16.
617 | 
618 |   If the disclaimer of warranty and limitation of liability provided
619 | above cannot be given local legal effect according to their terms,
620 | reviewing courts shall apply local law that most closely approximates
621 | an absolute waiver of all civil liability in connection with the
622 | Program, unless a warranty or assumption of liability accompanies a
623 | copy of the Program in return for a fee.
624 | 
625 |                      END OF TERMS AND CONDITIONS
626 | 
627 |             How to Apply These Terms to Your New Programs
628 | 
629 |   If you develop a new program, and you want it to be of the greatest
630 | possible use to the public, the best way to achieve this is to make it
631 | free software which everyone can redistribute and change under these terms.
632 | 
633 |   To do so, attach the following notices to the program.  It is safest
634 | to attach them to the start of each source file to most effectively
635 | state the exclusion of warranty; and each file should have at least
636 | the "copyright" line and a pointer to where the full notice is found.
637 | 
638 |     {one line to give the program's name and a brief idea of what it does.}
639 |     Copyright (C) {year}  {name of author}
640 | 
641 |     This program is free software: you can redistribute it and/or modify
642 |     it under the terms of the GNU General Public License as published by
643 |     the Free Software Foundation, either version 3 of the License, or
644 |     (at your option) any later version.
645 | 
646 |     This program is distributed in the hope that it will be useful,
647 |     but WITHOUT ANY WARRANTY; without even the implied warranty of
648 |     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
649 |     GNU General Public License for more details.
650 | 
651 |     You should have received a copy of the GNU General Public License
652 |     along with this program.  If not, see <http://www.gnu.org/licenses/>.
653 | 
654 | Also add information on how to contact you by electronic and paper mail.
655 | 
656 |   If the program does terminal interaction, make it output a short
657 | notice like this when it starts in an interactive mode:
658 | 
659 |     {project}  Copyright (C) {year}  {fullname}
660 |     This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
661 |     This is free software, and you are welcome to redistribute it
662 |     under certain conditions; type `show c' for details.
663 | 
664 | The hypothetical commands `show w' and `show c' should show the appropriate
665 | parts of the General Public License.  Of course, your program's commands
666 | might be different; for a GUI interface, you would use an "about box".
667 | 
668 |   You should also get your employer (if you work as a programmer) or school,
669 | if any, to sign a "copyright disclaimer" for the program, if necessary.
670 | For more information on this, and how to apply and follow the GNU GPL, see
671 | <http://www.gnu.org/licenses/>.
672 | 
673 |   The GNU General Public License does not permit incorporating your program
674 | into proprietary programs.  If your program is a subroutine library, you
675 | may consider it more useful to permit linking proprietary applications with
676 | the library.  If this is what you want to do, use the GNU Lesser General
677 | Public License instead of this License.  But first, please read
678 | <http://www.gnu.org/philosophy/why-not-lgpl.html>.
