Curve Surface Intersect (CSI)

Author: Marcel Haasnoot
Date: 2007-02-20

Synopsis:

This script determines the intersection point between a curve and a surface. It iteratively searches for the smallest distance between a point on the curve and the nearest point on the surface. It makes use of the closestPointOnSurface node and the iterative algorithm of the ppdcc script (also in the MEL database).

Usage:

Source the script file in Maya to activate the CSI command.
First select the curve, then the surface, then invoke the CSI command.
It will determine the point of intersection in local and global coordinates, and the normal of the surface at that point. It will also draw a line from the origin to the point of intersection.
