Abstract:
A method for rendering three-dimensional graphics data, the method comprising:receiving a set of three-dimensional graphics data representing a plurality of primitives, wherein each primitive comprises one or more vertices;translating said one or more vertices to view clipping coordinates based on a selected viewpoint, wherein said translating includes generating Z-values for the one or more vertices, wherein the Z-values vary from one at a front clipping plane to near zero at a back clipping plane; andscan converting the primitives into pixels, wherein said pixels are displayable to form an image, wherein said translating is accomplished by applying a formula substantially equivalent to Z=Wf/w, wherein Z is the Z-value being calculated, wherein w is a scaled distance along a z-axis from the selected viewpoint to the vertex being transformed, and wherein Wf is a value of w at the front clipping plane.
