Abstract : Real-time animation of characters often relies on a geometric technique called skinning which enables the skin and clothes to follow the skeleton motion. However, dynamic effects - non-rigid tissues vibrations, dynamic wrinkles of skin and clothes - can not be generated by it. However such deformations are of primary importance for the realism of the generated animation. In this paper, we propose two intuitive methods which address those specific problems with little increase in computational cost of the animation. Our tools can be combined together on an existing animation sequence to enhance its realism, with no need to change the original animation, no mechanics precomputation and no modification of the model. We illustrate our results with several characters and animals animations.
