An exact interactive time visibility ordering algorithm for polyhedral cell complexes
Proceedings of the 1998 IEEE symposium on Volume visualization - VVS '98
A visibility ordering of a set of objects, from a given viewpoint, is a total order on the objects such that if object a obstructs object b, then b precedes a in the ordering. Such orderings are extremely useful for rendering volumetric data. We present an algorithm that generates a visibility ordering of the cells of an unstructured mesh, provided that the cells are convex polyhedra and nonintersecting, and that the visibility ordering graph does not contain cycles. The overall mesh may bedoi:10.1145/288126.288170 dblp:conf/vvs/SilvaMW98 fatcat:xxcqhr3jdfdkdhyq576c7qktku
