AN INTERACTIVE APPROACH TO PLANNING SNAKE MOTION

Abstract

One of the most challenging research topics in computer animation is to model the motion of living animals, such as snakes. In this paper, we propose a new structure for modeling a snake's body and use an approach called sequential-goal constraints to simulate various motions of snakes. With this model, a snake's motion is simulated by assigning a sequence of control points along the snake's path and scheduling the times at which the snake passes through these points. The velocity of the snake's motion and the type of movement can be adjusted to meet the requirements of various animated scenarios. The outcome of the animation sequence is smooth and realistic.
