Abstract

In recent years, to achieve physics simulations in real-time, various attempts have been made on system architectures for speedup of simultaneous visualization and computation. We have been developing a high speed numerical computation platform for real-time physics simulations, which will be applied to practical surgical simulators. In the paper, we report techniques for the deformation of the human organs with GPU (Graphics Processing Unit) and its performance evaluations. The experimental result shows that the computation implemented in GPU is 10 times faster than CPU when the size exceeded more than 50,000 dimensions. In addition, we have confirmed that the method applied in the on going prototype surgical simulators can simulate deformation of kidney model (22, 324 Finite elements, 4,771node) in real-time.
