Local Illumination
�GPU designed for efficient local illumination computations to make video games more interesting
�Bump mapping, BRDF
�Vertex shader processes per-vertex attributes (normal, texcoords, color)
�Displacement mapping, skinning
�Rasterization interpolates vertex attributes across pixels
�Projective, perspective correct
�Pixel shader computes colors from interpolated values and texture lookups
�texture shading, perspective texturing
