This is the source code of an OpenGL graphics engine I wrote back in 2006 using C++, at least part of it. I didn't have the time to organize the code nor to compile specific demos. I just took the cpp and header files and committed everything as-is. Project files and assets are not included. You can find some demos at http://www.pedroedrasousa.com/. Nevertheless the source code may be useful to someone. I found it mostly useful when I started writing a graphics engine for Android.
###Some features:
- Bitmap Image Processing
- Per-Pixel Lighting
- Projective Texturing
- Stencil Shadow Volumes
- Post Processing Shaders
- Frustum Culling
- Quadtrees
- Useful math stuff (Vectors, Matrices, B-Splines, etc.)
