I'm new with performer, but I'm trying to modify perfly to shoot a ray
strait down to find the first intersection with the current geometry.
I want to stay a constant height above the non-uniform ground terrain
(shouldn't that be easy?).
This is the code I was trying but the function pfuCollideGrnd always
returns a zero indicating there was no intersection. I know that
there is in fact an intersection. So on return the function returns
a zero, height is minus one, and pitch and roll are both zero.

pfuGetXformerCoord(ViewState->xformer, &ViewState->viewCoord);
pfuCollideGrnd( &ViewState->viewCoord, ViewState->sceneGroup, zpr );
ViewState->viewCoord.xyz[2]=zpr[0]+10;

What am I doing wrong?
