Sorry. I guess I didn’t fully understand why you wanted to do the

Thanks Travis, that’s *exactly* the info I was looking for. I think I’m going to
go ahead and store each object’s matrix, as well as the camera and projection
matrices, updating any of them only when adjustments are made to the appropriate
objects, and I’ll perform the transformation calcs every time for every object
during the draw routine.Your numbers suggest there is no benefit from storing
the transformed data. Thanks again for all the detail.
