Hi Burr, actually even if it did depend on their tessellator I would be able to use it - that tessellator is in the library and I can use it if I want to.

I don't use it not because it is not available, but rather it did not do what I needed it to do, like wasn't fast enough for display meshing, didn't generate n-gons for export meshing, had problems like triangle leaks too often, and some other things...

But yeah a subdivision surface would be a new kind of surface construction method that would be used in addition to things like sweeping, lofting, etc... It would be like "make surfaces from this point cage". It doesn't really have anything specific to do with the tessellator.
