Abstract
Vertex data can be accessed for a graphics primitive. The vertex data includes homogeneous coordinates for each vertex of the primitive. The homogeneous coordinates can be used to determine perspective-correct barycentric coordinates that are normalized by the area of the primitive. The normalized perspective-correct barycentric coordinates can be used to determine an interpolated value of an attribute for the pixel. These operations can be performed using adders and multipliers implemented in hardware.
