If we just keep using four patches around every vertex, can we still allow more connectivity by introducing more points and making each patch smaller? The idea is like taking the limit.
Do we need higher level B patches to enable more patching at one vertex?
What happens if we try to match up more than 4 patches?
Why is it necessary to have only 4 patches around a vertex?
Does this 4 patches meeting have to do with principal curvature of a surface and being able to form a sort of "grid" over local regions of a surface?
What does "constrain" mean? Does it mean that 4 patches not allow objects to have its original shape?
