| Abstract | We present a hybrid 2D/3D algorithm for effeciently deriving a normal map of displacement-mapped polygonal geometry. Unlike the traditional bump-mapping approach by [Blinn 1978], ours is based on a physical representation of the true displaced mesh. It is therefore more accurate and less restrictive, easily handling a variety of procedural displacements. What makes our approach unique is that it does not entail finely tessellating the polygonal mesh or dicing it into REYES micropolygons. |
