Lescegra
Lescegra is an OpenGL 3D engine and game framework, written in strict ANSI C. It has a very clean, object oriented design, and is easily extensible.
Progress
| Section | Progress |
|---|---|
| Multipass Rendering | 70% (interface basics, stencil shadow render manager) |
| Rigid Body Physics | 80% (using ODE) |
| Collision Detection | 80% (using ODE) |
| Audio | 0% (probably using OpenAL) |
| Embedded Scripting Language | 40% (SWIG interface file generator, simple (non-oo) guile bindings) |
Mission Statement
- Simplicity -- The interface and the rendering/animation process should be easy to understand and mostly self explaining even for novices.
- Flexibility -- It should be easy to integrate lescegra into existing projects, whatever toolkit, operating system or architecture is used.
- Extensibility -- It should be easy to extend lescegra with custom functionality.
- Lightweight -- Keep the dependencies to a minimum without reimplementing too much functionality.
