MODELING BASED ON FEATURE OF COMPLEX SCULPTURE PROFILE

Based on analysis of complex sculpture profile, three kinds of feature definition methods are presented:classification definition, functional definition and shape definition. It approaches the feature description method of sculpture object, and improves a path enveloping method to describe the geometric information of sculpture object. The data structures with double links and four tables are designed. The four topological relationship of split, sticking, inserting and swing and its feature model are also built.
