GRAPHICS ADAPTER HAVING A VERSATILE LIGHTING ENGINE

A graphics adapter having a versatile lighting engine is disclosed. The graphics adapter generates graphics objects in a graphics scene. Each of the graphics objects within the graphics scene is made up of a number of polygons that are delimited by a set of vertices. The graphics adapter includes a graphics pipeline and a control module. In response to attributes received from a graphics software application, the control module selectively controls a frequency in which vertices are fed into the graphics pipeline and controls a number of concurrent calculations that are performed on the vertices within the graphics pipeline.
