Abstract
A method and apparatus are described for generating images from assembled polygonal image primitives. As a precursor to rendering, an ordered list of the primitives is assembled with degenerate cases being identified and discarded. Following removal of the degenerate cases, the remaining primitives undergo a series of tests to identify special cases whereby account can be taken of the rendering technique of omitting the right hand pixel of a span and bottom span of a primitive to simplify the rendering operation.
