Abstract :
This paper studies the problem of real-time rendering of highly deformable generalized cylinders. Some efficient schemes for high axis curvature detection are presented, as well as an incremental non-uniform sampling process. We also show how the recent 3D card "skinning" feature, classical in character animation, can be derived in order to allow for very high frame-rate when rendering such generalized cylinders. Finally, an algorithm is presented, that permits the object to dynamically adapt its display process, for guaranteed frame-rate purposes. This algorithm dynamically modifies the different sampling parameters in order to achieve optimal quality visualization for a given pre-imposed frame-rate.
