We present the novel technique to compute ambient occlusion [2008] on real-time graphics hardware. Because current real-time ambient occlusion techniques like SSAO need at least 16 rays sampling and too high computational cost to implement on computer games. Our method approximates occlusion as a local illumination model by introducing curvature-dependent function.
