| summary |
A previously reported method for finding the points of intersection of a vector and a parametric surface patch is examined. However, before the point of intersection of a vector and a patch can be determined, it is necessary to find the patch (or patches) on a multipatch surface intersected by the vector. A technique is described for determining the patch or patches intersected by a vector, given the patches intersected by a single plane containing the intersecting vector. Once these have been found, the point of intersection can be determined and the distance to the multipatch surface obtained |
