Simulation, Visualization, and Haptization of Elastic Objects

― Haptics for Virtual Reality and its Medical Applications ―

Abstract

Many studies of real-time deformation simulation approach for elastic objects are intensively performed in the field of computer graphics and virtual reality (VR). In particular, in order to generate and present a tactile sensation when touching the elastic objects, it is necessary to perform deformation simulation with high frequency. Therefore, acceleration approaches for deformation simulation are required.

In this article, we introduce several real-time deformation simulation approaches; online re-mesh deformation simulation, multi-rate deformation simulation, embedded deformation simulation, an acceleration approach of corotated deformation simulation by adaptive rotation extraction and deformation simulation, and impulse deformation model. In addition, we also introduce examples of its medical application.
