Fast Backface Culling Using Normal Masks - Zhang, Hoff, III (1997) (17 citations) (Correct)
....dot product between the polygon s normal and the vector formed from the viewing point to any point on the polygon. If the result is negative then the polygon is facing towards the viewer; if the result is positive then the polygon is facing away from the viewer and is considered to be backfacing. [KUMA96] has proposed a backface culling method that, in theory, can achieve sublinear performance. This method groups polygons and then uses frame to frame coherence to identify, track, and cull entire backfacing patches. This method achieves sublinear performance since it culls away polygons by groups. ....
....our normal clustering scheme and then focuses on the method by which these clusters are encoded with normal masks. 2.1 Normal Clustering Grouping normals into clusters is not a new idea. Previously, normal clustering has been used for various purposes, including hierarchical backface culling [KUMA96] and backface culling of curved surfaces [SHIR93] In these papers, the authors clustered the normal directions in a variety of ways; for example, Shirman partitioned the normal space into normal cones . Our method is a simple alternative. We partition the normal space by subdividing the ....

....are salient for many applications, including visualization [LE97] and shape analysis [BV95, Cro77] We present a technique for ecient tracking of perspective accurate silhouettes by reducing the problem to point location queries. Perspective accurate silhouette computation is known to be dicult [KM96, KM98, KMGL96]. Note that silhouettes formed under perspective projection are signi cantly di erent from those under parallel projection and are more dicult to compute. Given a polyhedral model with well de ned normals, the polygons (facets) whose normals point away from the viewpoint are called back facing. ....
