Vertex Shader program implementing "Image Based Lighting" with spherical harmonics as described in the Siggraph 2001 paper "An Efficient Representation for Irradiance Environment Maps" by Ravi Ramamoorthi and Pat Hanrahan. In addition to spherical harmonics lighting the mesh is shaded with a prebaked ambient occlusion map (blender uv-unwrap) to further refine the fake global illumination impression.
