Abstract
The present invention is directed to a method for rendering a computer graphics primitive intersected with one or more user-defined clipping planes. The method includes receiving a primitive, a clipping plane and a default scissor window; determining a second scissor window according to the spatial relationship among a first scissor window, the clipping plane and the vertices of the primitive; determining a group of pixels to be rendered by eliminating pixels not covered by an adjusted scissor window from the primitive; and determining a group of actually rendered pixels, in which the actually rendered pixels determining step includes removing the pixels meeting a clipping criterion from the group of pixels to be rendered. The present invention also includes an apparatus for performing the method.
