Usual Graphical Pipeline

• List all the triangles to draw

• Get rid of a maximum of triangles

• Clipping (Frustrum) or Back Face Detection

• Compute the illumination at the vertex of the triangle

• Interpolate the result in the 2D Screen, taking into account the Deepth : Z-Buffer

Properties of the Graphics Pipeline

• Primitives are processed one at a time

• All analytic processing early on

• Sampling occurs late

• Minimal state required (immediate mode rendering)

• Processing is forward-mapping
