Hi,

     I had such amazing success with my last question many
thanks to Anders Follin and others, that I thought I would
try another question.

     I have a driving simulator and I want to record when the
operator drives off the road. Since the roads and surrounding
terrain are different colors/textures I wish to poll the terrain
under the vehicle to determine if the vehicle is on the road.
Currently I'm using pfHit to get the elevation from the terrain
and understand that I can get the pfGeoSet, pfGeode or the
intersected primitive in pfGeoSet under the vehicle.

     My question is how to I get the color index from the intersected
polygon under the vehicle? Any suggestions would be greatly appreciated.

thanks much,
Bob Shankle
