Volumetric plastic deformation

Abstract

Working with volumetric information is always challenging. Displaying, processing or modifying volumes requires in most cases processing a considerable part of them, if not the whole structure. Such delays might be inconvenient for applications which require fast or smooth interaction, like realistic rendering or virtual sculpting. This paper focuses on the volume sculpting paradigm. Making use of a haptic device for interaction, the solution presented here provides a smooth and physically correct force feedback. The deformation algorithm is designed to provide a fast visual response. Additionally, this method is able to operate with large volumes, since it was designed to create a progressive, and therefore, scalable simulation.
