Abstract
An apparatus and methods for rendering 3D-graphics images preferably includes a port for receiving commands from a graphics application, an output for sending a rendered image to a display and a geometry-operations pipeline, coupled to the port and to the output, the geometry-operations pipeline including a block for performing transformations. In one embodiment, the block for performing transformations includes a co-extensive logical and first physical stages, as well as a second physical stage including multiple logical stages. The second physical stage includes multiple logical stages that interleave their execution.
