Abstract: Facial reconstruction system of B-spline surface that deals with cross-sectional CT data is presented. Comparing with traditional method of skinning curves, it uses data re-sampling technique successfully to solve problems as twist in some complex area and to avoid generating huge amounts of control points. It can be used widely in the fields of contour surface making and visual medicine.
