"Interpolating Subdivision Meshes with Arbitrary Topology"
by D. Zorin, P. Schroeder, W. Sweldens (1996).
On a piece of paper write down the answers to these questions:
What kinds of functions can be represented exactly
with the regular Zorin subdivision scheme ?
How does one determine the position of a new edge-vertex
that lies between two non-regular vertices ?
How did Zorin et.al. choose the rules for determining the weights
for placing a new vertex next to an irregular one ?
