<DIV><FONT face=Arial size=2>Hi,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I have a vtk actor (from polydata), which is
intersected by a line. I want to find the coordinates at the point of
intersection (the actual point on the surface, rather than the closest
vertex). I was looking at the IntersectWithLine method for vtkCellLocator, but
I'm using Tcl, and I can't figure out how to implement it in Tcl.
(Although I figure this gives me the cell Id rather than the point
coordinate, but I can calculate the intersection point from there).</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>Can anyone help with either implementing this
in Tcl, or any other suggestions for finding the
intersection point?</FONT></DIV>
<DIV><FONT face=Arial size=2>Thanks</FONT></DIV>
