Most languages for GPU programs performing this task are based on C; commonly used ones include Gelato, Houdini VEX, and RenderMan.
Languages to control the device that performs this graphical task have largely made the fixed-function API obsolete; such languages are now used to program the rendering pipeline. Most languages for GPU programs performing this task are based on C; commonly used ones include Gelato, Houdini VEX, and RenderMan. It usually works by applying an(*) illumination model, then using an interpolation algorithm. The flat type of it is fast in part because it requires only a single normal for the entire polygon and uses the lighting equation only once per polygon. A normal is calculated and the lighting equation used for each vertex in the smooth type of it named for Gouraud, while slower still is a variety that uses a smoothly varying surface normal vector and is named for Phong. For 10 points, name this computer graphics method of illustrating depth by varying the level of darkness.
