| Summary: | 碩士 === 國立臺灣大學 === 機械工程學研究所 === 87 === There are two main goals included in the thesis: Design of geometry and topology kernel in CAD system and Method of topology operator on B-rep:
Design of geometry and topology kernel in CAD system:
Geometry and topology are the kernels of CAD system. Geometry includes many calculations, and topology gives the complete definition of solids. This thesis will implement the elementary design for the kernels of CAD system.
Method of topology operator on B-rep:
For calculation of solids, we don’t adopt Boolean Operator, we analyze the calculation from topology aspect, we put all calculations from geometry to topology, and complete the B-rep of solids.
