Abstract
The present invention is related to a computer graphics rendering system, method and program product for drawing a plurality of pixels in parallel. A computer graphics rendering system for drawing a plurality of pixels in parallel in accordance with the present invention comprises a set-up unit for calculating parameters of an apex of a polygon and the gradient values of the parameters inside of said polygon; a DDAX for calculating the relative position of a representative point of each stamp in relation to said apex of said polygon; a DDA color unit for calculating the parameters of said representative point on the basis of the parameters of said apex of said polygon, the gradient values of the parameters inside of said polygon and the relative position of said representative point; an SRAM module for storing a sampling pattern which is a combination of the relative position(s) of one or more sample point(s) in relation to said representative point; and a multiply arithmetic circuit for calculating the parameters of said one or more sample point(s) on the basis of the parameters of said representative point, the gradient values of said parameters and the relative positions of said sample points.
