Tóm tắt

A free-form surface can be partitioned into different convex, concave and saddle regions thanks to the characteristics of surface curvatures at points on the surface. This paper presents the work of surface curvature computation for free-form surface partitioning. The surface curvatures are used as data for partitioning and defining the boundaries of regions on the surface when using the characteristics of surface geometry and the chain code technique in image processing field. The computation process is performed by a Matlab software. The input-data of the program are mathematical equations of free-form surfaces in explicit form or B-spline surfaces. The coordinates of points on the surface and on the region boundaries in the output data are used for modeling the surface with separate regions in CAD environment.
