First of all, thank you for your interest in this project! It started as an educational exercise for myself, to get a feel of various existing rendering APIs and engines; but can also be useful to other people (I hope :-))
If you want to add a new version, I would suggest first opening an issue with the 'additional version' tag: somebody might already be working on it. Please keep in mind that each new version should implement the same scene using either:
- a high-level rendering engine (Unreal Engine, CryEngine, ...)
- a lower-level toolset (for instance Godot, ThreeJS, ...)
- or an even-lower-level API (OpenGLES, DirectX, ...).
Homebrew versions and support for old/weird platforms or APIs are more than welcomed!
If you would rather want to rewrite one of the existing versions in another programming language (Go + OpenGL or Objective-C + Metal, for instance), I would rather suggest that you create a new fork, but feel free to add a link to it in the main README.md.
When everything is ready, submit a pull request with your new version placed in a directory at the root of the repository (the same way as the existing versions). Please add a README.md file with some details on the toolchain used, a few images of the result, any precisions you think are necessary, and feel free to credit yourself :) Also add a link in the root README.md.
Feel free to use the models and textures, their highest quality version is in the ressources directory of the OpenGL version. The 3D models of Suzanne and the Stanford dragon remain under their original licenses, same for the Miramar cubemap (credit of Jockum Skoglund/Hipshot).
