I'm new to performer and I'm working my way through a few of the example
programs. In the text3D.C example in the libpf/C++ directory, I wanted to
see the bounding sphere change as the text strings get longer.

To do this, I've put the following calls into the main loop of the program:
(i.e., these get called every frame)

scene->setBound(NULL, PFBOUND_DYNAMIC);
scene->getBound(&bsphere);

The problem is that the bounding sphere's size never changes. It's correct
at the begining of the program, but as the text strings get longer, the
bounding sphere does not increase.

Has anyone tested bounding spheres on 3D text?

Thanks,

Rachael Brady
