Abstract
A hardware-accelerated recirculating programmable texture blender/shader arrangement circulates computed color and alpha data over multiple texture blending/shading cycles (stages) to provide multi-texturing and other effects. Up to sixteen independently programmable consecutive stages, forming a chain of blending operations, are supported for applying multiple textures to a single object in a single rendering pass.
