분리형 삼각형을 기준으로한 입체모델링에 관한 연구

A solid modeller was developed in this paper. Representation scheme of modelling is nonmanifold B-rep. While many B-rep modelers use edges as basic element of modelling, this modeller is triangle-based. New modelling element, split triangle that is composed of 3 pure half-edges and has no information about the adjoining triangles, was defined to enlarge the range of representation. Corresponding algorithms for Boolean set operations were also developed.
