 1 | # Changelog
 2 | 
 3 | This project uses compatible versioning (https://gitlab.com/staltz/comver).
 4 | 
 5 | As Elmyra internally creates blender files (and lets you export and import them back), each release is tied to a certain Blender version to define a frame of compatibility for usage. For each Elmyra release that upgrades to a new blender version the compatible blender release will be listed in parentheses.
 6 | 
 7 | ## 1.0 (Blender 2.82)
 8 | 
 9 | - Elmyra has been upgraded to work with the new Blender 2.80 series, starting at 2.82 for this release
10 | - The server implementation has been completely rewritten in Rust
11 | - A multitude of command line configuration options have been added
12 | - The frontend build process has been migrated to a more modular, bundling based approach
13 | - All frontend/backend dependencies have been updated to their latest versions
14 | - About half of the frontend component implementations have been refactored and modernized
15 | - The blend4web integration was removed (unclear blender 2.80 support, never made it past experimental stage)
16 | 
17 | ## Pre 1.0 (Blender 2.79)
18 | 
19 | The initial releases of Elmyra were unversioned, they may be of interest to you because they had server implementations in different languages (python/flask in the beginning, javascript/express after that). Other than for historical reference and consulting prior implementation strategies their history should by now have little relevane though.

--------------------------------------------------------------------------------
 1 | # Specifications for bundled dependencies in `lib/`
 2 | 
 3 | The officially maintained library bundle is available at https://files.apertus.org/elmyra/elmyra-lib.zip
 4 | 
 5 | ## Platform dependencies
 6 | 
 7 | **The paths to the dependencies' executables need to be updated in the `src/[platform]/paths.json` manifests for every update!**
 8 | 
 9 | ### Blender 2.82
10 | 
11 | Blender can be bundled as-is except for one critical manual tweak, namely isolating its runtime environment from any user/system blender that might be installed on the machine where elmyra runs.
12 | For this simply create an empty `config/` folder in blender's `2.82/` directory. (see [Q/A on Blender Stackexchange](https://blender.stackexchange.com/questions/48392/make-blender-unaware-of-user-system-installed-add-ons))
13 | 
14 | ### FFmpeg 4.2.1+ or recent snapshot build from git
15 | 
16 | This refers to the executables (`ffmpeg`, `ffplay`, etc. though only `ffmpeg` itself is needed) and not to the `libav*` C libraries.
17 | 
18 | ## Asset dependencies
19 | 
20 | These are the blender files and image/font file assets Elmyra imports when it generates or updates visualizations. They are located inside `lib/elmyra/` and documented here for overview and development reference purposes.
21 | 
22 | - `environment.hdr`
23 | - `illustrated.blend`
24 | - `oxygen-mono.ttf`
25 | - `preview-widgets.blend`
26 | - `realistic.blend`
27 | - `section.blend`
28 |

 2 | 
 3 | An experimental blender-based rapid iterative visualization system.

 5 | [![Conference presentation video thumbnail](http://files.apertus.org/elmyra/screencast-youtube-screenshot.png?)](https://www.youtube.com/watch?v=l8x8Kz1T1uc "Elmyra Screencast")
 6 | 
 7 | ## Download for your OS
 8 | 
 9 | - [Linux (x64)](http://files.apertus.org/elmyra/elmyra-1.0-linux-x64.zip)
10 | - [macOS (x64)](http://files.apertus.org/elmyra/elmyra-1.0-macos-x64.zip)
11 | - [Windows (x64)](http://files.apertus.org/elmyra/elmyra-1.0-windows-x64.zip)
12 | 
13 | After extracting the `.zip` package, `cd` into the folder and run the executable with `./elmyra`. By default the server listens on all addresses and port `8080` and thus should be reachable from your browser at `localhost:8080`. Run `./elmyra --help` to see all configuration options. Note that you *don't* need to install blender or anything at all, everything comes bundled with the release package and should work out of the box. Blender data, image and video files, temporary runtime data, etc. are by default stored in folders next to the executable - this can be configured as well.
14 | 
15 | ## What is Elmyra?
16 | 
17 | - **Visualization Wizard** - Create animated or static visualizations from primitive 3D input files in the browser
18 | - **Automated Rendering** - Get a draft immediately and higher-quality versions delivered continuously over time
19 | - **Continuous Delivery** - Share/embed links to images/videos that always deliver up-to-date material
20 | - **Blender Inside** - At its core Elmyra uses [Blender](https://www.blender.org/), all visualizations can be downloaded as blender files
21 | - **Free & Open Source** - Developed as a part of the [AXIOM Gamma](http://apertus.org/axiom-gamma) project
22 | 
23 | For a quick introduction watch the [Elmyra Screencast](https://www.youtube.com/watch?v=l8x8Kz1T1uc), also linked above. (8min)  
24 | For more project history and background check out the [Blender Conference 2015 Presentation](https://youtu.be/ht1hPNjQxcY?t=24s) . (23min)
25 | 
26 | ## Express permission to innovate
27 | 
28 | Elmyra is not a finalized product idea for consumation only, but a solid, approachable codebase modeling a different paradigm of how industrial/architectural/etc. visualization can be reimagined. You are expressly invited to build on our research and development, reinvent Elmyra's vision, hack it, fork it, extend it, make it your own and share your developments with the community. We're excited to hear what you come up with and glad to help out with know-how on the codebase where we can, feel absolutely free to open an issue and ask for help.
29 | 
30 | ## Building from source
31 | 
32 | ### Get the source code
33 | 
34 |     git clone https://github.com/apertus-open-source-cinema/elmyra.git
35 | 
36 | ### Download the bundled dependencies and assets
37 | 
38 | Download and unzip the [bundled dependencies and assets](http://files.apertus.org/elmyra/elmyra-lib.zip) and put the `lib` folder inside Elmyra's root directory.
39 | 
40 | ### Install language dependencies
41 | 
42 | Install [rustup](https://rustup.rs/) and [node.js](https://nodejs.org/).
43 | 
44 | Inside elmyra's root directory run the following:
45 | 
46 | ```
47 | rustup override set nightly
48 | npm install
49 | ```
50 | 
51 | ### Build and run it
52 | 
53 | By running `npm run build` you can now create a build for your platform. The
54 | finished build will be placed under `build/elmyra-[version]-[platform]-[arch]/` and to
55 | start it you simply execute the `elmyra` binary. By default the server listens
56 | on all network interfaces and the automatically assigned port is shown in the
57 | terminal output right on startup.
58 | 
59 | Use `./elmyra --help` to read up on available command line options like server
60 | address and port, as well as more advanced/exotic configuration options.
61 | 
62 | ## Versioning
63 | 
64 | Elmyra uses compatible versioning (ComVer)
65 | 
66 | [![ComVer](https://img.shields.io/badge/ComVer-compliant-brightgreen.svg)](https://github.com/staltz/comver)
67 | 
68 | ## Acknowledgements
69 | 
70 | Elmyra could not have been brought to life without the heart that beats at its core - [Blender](http://blender.org) - and its incredibly helpful and inspiring community; It would not even closely be what it is without [FFmpeg](http://ffmpeg.org) and its hardworking volunteer force; and in the first place, it could not have been conceived without the individuals and organizations that created this open, enabling environment for it to grow in - the AXIOM project. Thanks so much everyone!
