说明：  In the last decade the processing of polygonal meshes has emerged as an active and very productive research area. This can basically be attributed to two developments:  Modern geometry acquisition devices, like laser scanners and MRT, easily produce raw polygonal meshes of ever growing complexity  Downstream applications like analysis tools (medical imaging), computer aided manufacturing, or numerical simulations all require high quality polygonal meshes as input. The need to bridge the gap between raw triangle soup data and high-quality polygon meshes has driven the research on ecient data structures and algorithms that directly operate on polygonal meshes rather than on a (most often not feasible) intermediate CAD representation.
