Faogen Fast Ambient Occlusion Generator. It uses OpenGL API to access video card GPU to accelerate computation of ambient occlusion and bent normals both as per-vertex data and in texture images. 2.0 version provide updated ambient aperture and bent normals shaders with ability to customize them through editing of GLSL code of two simple functions. Other features include improved precision on large scale models, adjustable background for AO texture images, lighting animation control and few bugfixes. Bent normals rendering instead of vertex normal uses special vector, which points in the average direction of unoccluded samples. This technique is simple and can be used even on pre-shader hardware. Ambient aperture rendering is more complicated and adds cheap dynamic shadows to view.
