I need to transform a world coordinate point to screen coordinates. I know
that I need to call XformPt3 on the point, but I can't figure out where the
matrix (or matrices) come from. I tried pfGetChanViewMat and
pfGetChanOffsetViewMat, but they dont give the correct results. It seems
that I need to be transforming by two matrices - one from world to local
coords and then again from local to screen coords.

A small snippet of code would be wonderful and appreciated.

Thanks,
Bill Volz
