This is the third Bellairs Workshop on Computer Animation. This year, the focus will be on problems in to animation and geometry, with a special emphasis on related research projects in the GRAND NCE.

The workshop will bring together GRAND network investigators and other international experts in the animation and geometry communities. These communities do not typically work together; they usually attend different symposia, and do not often collaborate despite important connections between geometry and animation. This workshop will be a venue where these communities can join to focus on a selection of challenging problems where a cross fertilization of knowledge in modeling and animation can be of benefit. Topics may involve problems related to modeling, parameterization, capture and simulation of human motion and natural phenomena, physically based simulation and control. The goal is to assemble a synergistic mix of researchers to work on GRAND challenges, share ideas, define future research directions, and to develop new or existing collaborations.

The workshop will consist of a variety of activities, including keynote talks to frame the discussion, breakout sessions for participants to discuss topics in small groups, and a session for interactive demos. There will also be plenty of time for informal discussions. Additionally, the Bellairs facilities are relatively primitive (and inexpensive), so there are few distractions such as those typically found in hotels.

Accommodation is very basic (double occupancy only), and with partial board costs approximately 50 USD per day. Reservations must be made through the workshop organizer. Due to space limitations, participation at the workshop is by invitation only.

The workshop will take place at McGill University's Bellairs Research Institute and will be held Saturday 19 to Tuesday 22 February. Participants should plan to arrive Friday 18 as the Saturday session will start at 9:00 am. Departure can be as late as Friday 25th, and participants are strongly encouraged to take advantage of the additional days in order to continue discussions and to work on collaborative projects.
