Abstract :
Current approaches to realistic skeleton animation are based on the anatomy of animating subjects which are skeletal muscles and tendons. This is too complex for interactive animation. A curve based method uses curves to render surfaces, which show deformations in real-time, but because of its lacks of anatomical information, manual effort is done by animators to demonstrate realism. To have a natural looking animation, a model must have both topological and geometrical information this can be represented by Reeb graph and its contours. We propose an alternative to surface based method with more realism but still interactive to work as a tool for 3D character animation by employing Tensegric model to control deformations, Harmonic skeletal method to automatically construct Reeb graph with anatomical information and its contours.
