Abstract

The Rainbow group has contributed a lot to this subject in the past five years, and it seems appropriate to let the rest of the group know what has been done and what is going on at the moment.

The talk will cover a bit of introduction and history, and then address what the group has done, what we are currently addressing, and what the main remaining challenges are.

Although there is a lot of maths under the bonnet, this will be exposed only on demand. A key idea is that subdivision is actually about the HCI problem of letting a shape designer (animator, car stylist …) express conveniently to the computer a precise description of the shape in mind (even though what is in mind is not very precise).
