Patch dicing

[Vivek Narayanan <vnast+@pitt.edu>]

Hi,

I've noticed, and the geomview manual also says, that Bezier patches are
first converted to meshes before drawing them. 
Could you refer me to the algorithms/code that was used to do this
conversion ? Since I'm planning to use Geomview for my thesis work, this
information is quite critical for me.

Thanks.
