Periodic b-spline surface skinning of anatomic shapes.

Abstract

this paper, we present a method for smooth closed surface approximation from 2D contours. Both the section curves and the skinned surface are approximated. This allows to reduce dramatically the amount of initial data while preserving the accuracy. Here, we are interested in single contour sections, but the handling of multiple contours is presented in the conclusion. Moreover, the resulting surfaces can easily be manipulated in an interactive system, with the help of the numerous techniques developed for the shape modification of B-spline curves and surfaces
