That's what I was talking about. It's of course possible to do OpenGL 
rendering in software (Mesa <http://www.mesa3d.org/> is a popular 
open-source implementation used on Linux, Mac OS X and Windows have 
their own software renderers, and I'm sure there are others). But for 
the simple kind of graphics Pipmak uses, going through a full-featured 
3D renderer is much less efficient than what a specialized renderer 
could do. The only reason to use OpenGL for Pipmak is that with today's 
graphics hardware, the capability for fast OpenGL rendering is there, 
and making use of it is much simpler and faster than letting the GPU sit 
idle and doing the work on the already busy CPU (even though it could be 
done more efficiently there).

Just try running Pipmak on a Mac or PC without (supported) 3D hardware: 
you'll see that it runs just fine, but it's very slow - much slower than 
e.g. QuickTime VR, which does its own software rendering.
