That is looking good indeed. I need to ponder this a bit more; I think I 
know how to do this but I want to examine all the angles, so to speak. I 
can see the advantage of this procedure and it would avoid the 
subdividing of the container in discrete elements.

Saving the point locations is certainly an excellent idea. I shall 
certainly come to that eventually.

Well done indeed.
