Summary:The paper presents a general approach for designing and animating
complex deformable models with implicit surfaces. Implicit surfaces are
introduced as an extra layer coating any kind of structure that moves
and deforms over time. Offering a compact definition of a smooth surface
around an object, they provide an efficient collision detection
mechanism. The implicit layer deforms in order to generate exact contact
surfaces between colliding bodies. A simple physically based model
approximating elastic behavior is then used for computing collision
response. The implicit formulation also eases the control of the
object's volume with a new method based on local controllers. We present
two different applications that illustrate the benefits of these
techniques. First, the animation of simple characters made of
articulated skeletons coated with implicit flesh exploits the
compactness and enhanced control of the model. The second builds on the
specific properties of implicit surfaces for modeling soft inelastic
substances capable of separation and fusion that maintain a constant
volume when animated
