2 | ===================
3 |
4 | Asynchronous load, compile, and link webgl shader programs
5 |
6 | ```html
7 |
8 | ```
9 |
10 | 
11 |
12 | Shaders can be fetched and compiled independently. Images used for textures
13 | can also be fetched asynchronously. This library helps you load, compile,
14 | and link shaders and images without waiting for each other, other than a
15 | vertex or fragment shader waiting to link with its compiled other half.
16 |
17 | ##Load WebGL Programs From Shader URL Pairs And Images From URLs
18 | ```javascript
19 | var shaderUrls = ['vertex1.glsl', 'frag1.glsl', 'vertex2.glsl', 'frag2.glsl'];
20 | var imgUrls = ['texture1.jpg', 'texture2.jpg', 'texture3.jpg'];
21 |
22 | WebGLShaderLoader.load($gl, shaderUrls, imgUrls, function (errors, gl, programs, images) {
23 | if (errors.length) return console.error.apply(console, errors);
24 |
25 | console.log(programs, images);
26 | gl.useProgram(programs[0].program);
27 | gl.uniform1f(programs[0].uniforms.uTime, 42.0)
28 | });
29 | ```
30 | `$gl` can be an existing webGL context or a canvas element (in the DOM or not).
31 |
32 | `shaderUrls` is an array of strings of URLs to shaders. Expects pairs of atleast one,
33 | alternating vertexShaderURL, fragmentShaderURL.
34 |
35 | `imgUrls` is an array of strings of URLs to `![]()
`s. May be empty or null.
36 |
37 | `errors` is a possibly empty array of strings.
38 |
39 | `gl` is a webGL context, regardless of `$gl`.
40 |
41 | `programs` is an array of objects, in order of the pairs. The objects contain
42 | the keys `attributes`, `program`, and `uniforms`. `program` is the
43 | WebGLProgram, ready for use. The `attributes` and `uniforms` keys point to
44 | objects whose keys are the identifiers and values are the locations.
45 |
46 | `images` is a possibly empty array of img elements ready to be sampled.
47 |
48 | ##Load WebGL Program From Shader String Literals
49 | ```javascript
50 | var loader = new WebGLShaderLoader(gl);
51 | loader.loadFromStr(vertexShaderStr, fragmentShaderStr, function (errors, program) {
52 | if (errors.length > 0) {
53 | console.error.apply(console, errors);
54 | return;
55 | }
56 |
57 | console.log(program);
58 | });
59 | ```
60 |
61 | ##Load WebGL Program From XHR'd Files
62 | ```javascript
63 | var loader = new WebGLShaderLoader(gl);
64 | loader.loadFromXHR(vertexShaderPath, fragmentShaderPath, function (errors, program) {
65 | if (errors.length > 0) {
66 | console.error.apply(console, errors);
67 | return;
68 | }
69 |
70 | console.log(program);
71 | });
72 | ```
73 |
74 | ###Notes
75 | * Look at test.js for further usage/example
76 | * errors is an array of strings of usage, compilation, and linkage errors, it's up to you to check these.

183 | If You distribute Covered Software in Executable Form then:
184 |
185 | a. such Covered Software must also be made available in Source Code Form,
186 | as described in Section 3.1, and You must inform recipients of the
187 | Executable Form how they can obtain a copy of such Source Code Form by
188 | reasonable means in a timely manner, at a charge no more than the cost
189 | of distribution to the recipient; and
190 |
191 | b. You may distribute such Executable Form under the terms of this License,
192 | or sublicense it under different terms, provided that the license for
193 | the Executable Form does not attempt to limit or alter the recipients’
194 | rights in the Source Code Form under this License.
195 |
196 | 3.3. Distribution of a Larger Work
197 |
198 | You may create and distribute a Larger Work under terms of Your choice,
199 | provided that You also comply with the requirements of this License for the
200 | Covered Software. If the Larger Work is a combination of Covered Software
201 | with a work governed by one or more Secondary Licenses, and the Covered
202 | Software is not Incompatible With Secondary Licenses, this License permits
203 | You to additionally distribute such Covered Software under the terms of
204 | such Secondary License(s), so that the recipient of the Larger Work may, at
205 | their option, further distribute the Covered Software under the terms of
206 | either this License or such Secondary License(s).
207 |
208 | 3.4. Notices
209 |
210 | You may not remove or alter the substance of any license notices (including
211 | copyright notices, patent notices, disclaimers of warranty, or limitations
212 | of liability) contained within the Source Code Form of the Covered
213 | Software, except that You may alter any license notices to the extent
214 | required to remedy known factual inaccuracies.
215 |
216 | 3.5. Application of Additional Terms
217 |
218 | You may choose to offer, and to charge a fee for, warranty, support,
219 | indemnity or liability obligations to one or more recipients of Covered
220 | Software. However, You may do so only on Your own behalf, and not on behalf
221 | of any Contributor. You must make it absolutely clear that any such
222 | warranty, support, indemnity, or liability obligation is offered by You
223 | alone, and You hereby agree to indemnify every Contributor for any
224 | liability incurred by such Contributor as a result of warranty, support,
225 | indemnity or liability terms You offer. You may include additional
226 | disclaimers of warranty and limitations of liability specific to any
227 | jurisdiction.
228 |
229 | 4. Inability to Comply Due to Statute or Regulation
230 |
231 | If it is impossible for You to comply with any of the terms of this License
232 | with respect to some or all of the Covered Software due to statute, judicial
233 | order, or regulation then You must: (a) comply with the terms of this License
234 | to the maximum extent possible; and (b) describe the limitations and the code
235 | they affect. Such description must be placed in a text file included with all
236 | distributions of the Covered Software under this License. Except to the
237 | extent prohibited by statute or regulation, such description must be
238 | sufficiently detailed for a recipient of ordinary skill to be able to
239 | understand it.
240 |
241 | 5. Termination
242 |
243 | 5.1. The rights granted under this License will terminate automatically if You
244 | fail to comply with any of its terms. However, if You become compliant,
245 | then the rights granted under this License from a particular Contributor
246 | are reinstated (a) provisionally, unless and until such Contributor
247 | explicitly and finally terminates Your grants, and (b) on an ongoing basis,
248 | if such Contributor fails to notify You of the non-compliance by some
249 | reasonable means prior to 60 days after You have come back into compliance.
250 | Moreover, Your grants from a particular Contributor are reinstated on an
251 | ongoing basis if such Contributor notifies You of the non-compliance by
252 | some reasonable means, this is the first time You have received notice of
253 | non-compliance with this License from such Contributor, and You become
254 | compliant prior to 30 days after Your receipt of the notice.
255 |
256 | 5.2. If You initiate litigation against any entity by asserting a patent
257 | infringement claim (excluding declaratory judgment actions, counter-claims,
258 | and cross-claims) alleging that a Contributor Version directly or
259 | indirectly infringes any patent, then the rights granted to You by any and
260 | all Contributors for the Covered Software under Section 2.1 of this License
261 | shall terminate.
262 |
263 | 5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user
264 | license agreements (excluding distributors and resellers) which have been
265 | validly granted by You or Your distributors under this License prior to
266 | termination shall survive termination.
267 |
268 | 6. Disclaimer of Warranty
269 |
270 | Covered Software is provided under this License on an “as is” basis, without
271 | warranty of any kind, either expressed, implied, or statutory, including,
272 | without limitation, warranties that the Covered Software is free of defects,
273 | merchantable, fit for a particular purpose or non-infringing. The entire
274 | risk as to the quality and performance of the Covered Software is with You.
275 | Should any Covered Software prove defective in any respect, You (not any
276 | Contributor) assume the cost of any necessary servicing, repair, or
277 | correction. This disclaimer of warranty constitutes an essential part of this
278 | License. No use of any Covered Software is authorized under this License
279 | except under this disclaimer.
280 |
281 | 7. Limitation of Liability
282 |
283 | Under no circumstances and under no legal theory, whether tort (including
284 | negligence), contract, or otherwise, shall any Contributor, or anyone who
285 | distributes Covered Software as permitted above, be liable to You for any
286 | direct, indirect, special, incidental, or consequential damages of any
287 | character including, without limitation, damages for lost profits, loss of
288 | goodwill, work stoppage, computer failure or malfunction, or any and all
289 | other commercial damages or losses, even if such party shall have been
290 | informed of the possibility of such damages. This limitation of liability
291 | shall not apply to liability for death or personal injury resulting from such
292 | party’s negligence to the extent applicable law prohibits such limitation.
293 | Some jurisdictions do not allow the exclusion or limitation of incidental or
294 | consequential damages, so this exclusion and limitation may not apply to You.
295 |
296 | 8. Litigation
297 |
298 | Any litigation relating to this License may be brought only in the courts of
299 | a jurisdiction where the defendant maintains its principal place of business
300 | and such litigation shall be governed by laws of that jurisdiction, without
301 | reference to its conflict-of-law provisions. Nothing in this Section shall
302 | prevent a party’s ability to bring cross-claims or counter-claims.
303 |
304 | 9. Miscellaneous
305 |
306 | This License represents the complete agreement concerning the subject matter
307 | hereof. If any provision of this License is held to be unenforceable, such
308 | provision shall be reformed only to the extent necessary to make it
309 | enforceable. Any law or regulation which provides that the language of a
310 | contract shall be construed against the drafter shall not be used to construe
311 | this License against a Contributor.
312 |
313 |

316 | 10.1. New Versions

333 | create a new license for such software, you may create and use a modified
334 | version of this License if you rename the license and remove any
335 | references to the name of the license steward (except to note that such
336 | modified license differs from this License).
