This paper presents a technology that enables an untrained user to draw and animate a quadruped in tens of seconds. The system recognizes a quadruped drawn by a user and creates a skeleton from the sketch. Following a few simple rules the user is able to draw the movement she wants the quadruped to do. The system will parse the sketch and interpret it to let the quadruped walk, jump, trot, gallop or sit. To do all of this the system uses several techniques to understand the drawings, as well as key framing, controller based animation and inverse kinematics to animate the quadruped.
We
want like to thank Dave Burke, Matthew Thorne and Michiel van de Panne for their
help and their kindness to allow our project to be based on their work. This
project would otherwise not have been possible in the amount of time available.
