A small, portable and extensible 3D coding framework written in C++:

  • simple Orthodox C++ coding style and APIs
  • extensible through external code modules living in git repositories
  • runs on OSX, Linux (incl RaspberryPi), Windows, iOS, Android, emscripten, from the same C++ source
  • renders through GL, GLES2, WebGL, Metal, D3D11 from same shader source
  • produces small executables (e.g. emscripten WebGL demos starting at around 100 Kbytes)
  • async data loading from web or disc

How to Build (Quick'n'Dirty):

You need: cmake, python and your platform's default C/C++ development environment.

> mkdir projects
> cd projects
> git clone --depth 5 https://github.com/floooh/oryol
