Hello, I thought I should post a IOTD for the first time of a simple demo I made. Ambient Occlusion, nothing special.

This demo trace rays distributed in a hemisphere to compute the average direction of unoccluded rays, which is an approximation of the average direcion of incident light. This is done for a finite set of points on a surface, in this case the result is encoded into a texture which is used to do soft real-time lighting.
