Volume Rendering for Curvilinear and Unstructured Grids

A hardware polygon rendering pipeline can be used together with hardware compositing to volume-render arbitrary unstructured grids composed of convex polyhedral cells. This technique is described, together with the global sorting necessary for back-to-front compositing, and the modifications that must be made to approximate curvilinear grids, whose faces may not be planar.
