36 Triage polygonization of rounded polyhedra

By Burkhard Wünsche and Richard Lobb


This paper describes a method for rounding and polygonizing edges and corners of polyhedral models to produce softer, more natural looking objects. The underlying rounded surface is assumed to be defined by ªquasiconvolutional smoothingº, and the focus is on polygonizing the surface rapidly and efficiently. A binary space partitioning (BSP) tree is used to classify space in the vicinity of a polyhedron to identify the curved regions. Planar surfaces are extracted as single polygons, and extra polygons are introduced only at rounded edges and corners. The result is a highquality polygonization of the rounded polyhedron with none of the fragmentation problems of more general polygonization methods
