What Dave Scherer was describing was indeed Python+PyOpenGL+Numeric.
It was precisely this combination that was not nearly fast enough to be 
usable.

He went from there to C++ as late as possible, with reluctance, because of 
course after going to C++ it became much more difficult to make changes and 
additions. Yes, precision and error checking are indeed important, but the 
central issue was raw speed.
