faogen is a fast ambient occlusion generator. Use your video card GPU to compute ambient occlusion really fast. Support both texture and per-vertex calculation. Input scene can loaded from Wavefront OBJ or LightWave 3D object (*.LWO) files (future versions will allow to use more file formats).
Faogen itself uses hardware shadow mapping, floating-point render targets and OpenGL Shading Language to compute ambient occlusion data. This process is much faster than any CPU-based approach.
