Enhanced shading with an ambient occlusion that is per vertex statically precomputed and rendered us
ShadeVis is a open source tool that computes simple static, per-vertex ambient occlusion term to provide more faithful shading for realtime rendering. The most common techniques to compute ambient occlusion is based on shooting rays from each surface element to evaluate the quantity of light that reach it. Shadevis tools use the OpenGL API to accelerate this process by simply rendering the scene ortographically from a set of uniformly distributed directions and checking against the zbuffer if each vertex is occluded or not.
