Virtual Open Heart Surgery Simulator using the OpenGL API and GPU

Real-time surgical simulators have existed for years, but complex models for thing like the heart, have been harder to achieve on desktop PCs. The Virtual Open Heart Surgery Simulator, developed at the University of Aarhus, Denmark, has moved the underlying computations from the CPU to the GPU to gain the required speed. The simulator, programmed using the OpenGL API, obtains simulation rates of 500 Hz on volumetric mass-spring systems of 30.000 particles. This rate includes also haptic feedback calculated at 500 Hz and visualisation of a normal mapped 80.000 faces surface.
