Implicit surface reconstruction for reverse engineering

摘要: ABSTRACT Implicit surface methods for reconstruction have received much attention in recent years. But implicit algorithmsreported literature are usually limited to a class of closed surfaces or require knowledge the topologies prior tosurface reconstruction. Here, general approach is proposed various types surfaces,including manifolds with boundaries and non-manifolds, without topology. A framework andan associated methodology also been defmed identity main tasks issues Anassessment algorithms reported has carried out.Keywords: surface, field function, 1. INTRODUCTION techniques widely used support reverse engineering. For example, mechanical part can be designed fabricated using CAD/CAM systems. Using laser scanning system
