Motion Doodles for Quadrupeds: How to Draw and Animate a Cat in 15 Seconds CPSC 533b Course Project Report

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.
