I see. Right now converting from IGES to STL is taking a long time.
The povray part is pretty quick. One other option that I am
investigating is using gmsh (which links to OCC) to load an IGES file
and then save an image (it has some image saving functions). The
problem is that the output of the GIF exporter looks like this:

But it is significantly faster, so a compiled tool (linking to gmsh)
might be better in the end. I don't know how fast occray is, it was
just announced this morning. An off-screen OpenGL renderer would be
even better. I guess I'll go back to digging through the OCC
code-base.
