Accurate solid modeling based on curved surface

Solid modeling system based on accuracy model achieves a higher level accuracy than faceted system, but many problems exist, such as complexities of geometric calculation. This article presents a new method for representing and maintaining accuracy information in a solid system. A structural representation is introduced, some operations and validity checking are explained.© (1996) COPYRIGHT SPIE--The International Society for Optical Engineering.
