Approximate volume rendering for curvilinear and unstructured grids by hardware-assisted polyhedron projection

Nelson Max, Peter Williams, Claudio Silva

Research output: Contribution to journalArticle


A hardware polygon rendering pipeline can be used 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 cells, whose faces may not be planar.
