GPU in haptic rendering of deformable objects

Abstract

We present some results regarding utilizing Graphics Processing Unit (GPU) for computing the deformation of two experimental objects. A suture simulation model with GPU and a 2D deformable cloth model with nVidia CUDA techniques are also proposed. We conducted experimental studies to compare the GPU-based suture models and with the CPU implementation. We also experimented with the implicit model of the 2D mesh which offer similar computational challenges associated with any Finite-Element modeling approaches. A method for computing the inverse of a matrix with truncated Neumann series is also introduced. © 2008 Springer-Verlag Berlin Heidelberg.
