ABSTRACT:
Dynamically constructing a scan line rasterizer in a rasterization engine includes selecting a base rasterizer, obtaining parameters describing the base rasterizer, obtaining at least one replacement block of code, allocating memory for a dynamically constructed rasterizer, copying the base rasterizer into the memory allocated for the dynamically constructed rasterizer, and copying the at least one replacement block into the base rasterizer stored in the memory using the parameters to form the dynamically constructed rasterizer.
