Lecture 8: Geometry Processing (54)

I understand that everywhere else needs C2 continuous surface, but why do we not need to enforce this constraint to extraordinary points?


I think that it's not that you don't want to enforce the constraint, but just that the math works out so that at extraordinary points, with the schema we have so far, this is the result.
