Popis: A new method for recovering shape from cross-sectional contours with complex branching structures is presented. First, each branching problem by providing an intermediate contour using distance function and image processing technology is solved. Then, all contours are divided into several groups of simple contours. For each group, a NURBS curve is fitted to contour points in each section within a given accuracy on a common knot vector. Finally, the NURBS surface skinning of these contours is performed for providing a smooth geometric model. The method is suitable to reproduce the object by NC machining or rapid prototyping. Some results demonstrate its usefulness and feasibility.
