An acquisition method for interactive deformable models

摘要

This work gives a brief review on deformable modeling in computer graphics and it summarizes our work on the acquisition of deformable models for interactive visual and haptic simulation. Our method for deformable model acquisition is based on data obtained with the UBC active measurement (ACME) facility. ACME is a robotic measurement system which is capable of recording the local deformation of an object based on manipulator force sensing and the global deformation based on our visual range-flow technique. We have acquired data for the robust estimation of elastic models including extensions to large scale deformation and viscoelastic object behavior. We re-iterate our results obtained for a plush toy, a medical physical soft-tissue wrist model and a triceratops rubber toy.
