summary |
A divide-and-conquer algorithm is presented for finding all the intersection lines between two B-spline surfaces. Each surface is organized as an n-branch tree. For each intersection line, an initial point is detected after a depth-first search along one tree, i.e. the host tree. Extrapolation methods are then used to trace the entire length of the line, thus the line appears naturally in a continuous form. Efficiency of the algorithm is achieved by employing of an adaptive division strategy and by the careful choice of the representation basis of the patches on both surfaces |
