My box modeler does this by extracting each face and generating the 
bicubic patches for each side.

The problem as I see it is how do I tell my modeling system "this bit is 
flat but that bit is round"?

As for the irregular grids, it's also not a matter of finding the 
quadrilaterals and drawing them, it's a matter of creating them and 
keeping track of them so I can traverse the irregular relaxed grid.

And yes, this is exactly all for this wave function collapse thing I'm 
building.
