This is a rewrite of my older game engine, with code dating back to 2007.
- Project Board
- Documentation
- Projects and Examples:
Features
- Cross-platform (Windows, Linux, and Mac(wip))
- Multi-threaded (more improvements here soon)
- OpenGL ES-compatible shader-based pipeline
- Forward rendering w/ multipass lighting
- Several shaders, including tangent-space bumpmapping
- Partitioner/culling support
- Automatic VBO baking of visible areas (10x framerate in many cases)
- Mesh instance copy-on-write vertex and shader attribute modifications
- Basic instancing
- Render-to-Texture
- Thread-safe OpenGL task handler
- C++ and (wip) Python support
- Multi-layer tilemap system for 2D games

- Callback scheduling
- Music and 3D Sound
- Powered by OpenAL
- Wav and Ogg support
- Thread-safe
- Cairo 2D primitives w/ Render-To-Texture
- Pango Font and Text Rendering
