Abstract

The objective of this research is to develop a tool for the generation of 3D objects modeled with flexible materials, with visco-elastic or inelastic characteristics, similar to the plasticine. It is desirable to prioritize the simplicity of the interface with the user in the interactive deformation process of the object. To compute the deformations of object which is exposed to external forces, like elements with which the modeling will be simulated, what implies the process between the deformable object and rigid ones.
