[ REQ 5879]: Geomview external module question

[jhills at liberty.uc.wlu.edu]

	I am a college student at Washington and Lee University. I am 
working with your geomview software over the summer on a constraints 
solving problem. The question I have concerns an external module which 
uses bi-directional communication. I am currently trying to develop a 
module which will allow a user to select a face of a geometry. I have 
seen example3, where points on the face or edge are selected, and this 
helps. However what I would like to do is change the color of the face 
the user selects. I have played around and can get all the index numbers 
for the edges as well as the coordinate points back to my module, however 
I can not find a good way to simply change the color or shape of a 
geometry which already exists. Is the only way to do this do redefine the 
entire geometry? Is there a way I can give it the face index 
and ask it to modify the given face?
