Real-time haptic rendering of three-dimensional fluid flow will improve
the interactivity and realism of video games and surgical simulators,
but it remains a challenging undertaking due to its high
computational cost. Humans are intensely familiar with the look
and feel of real fluids, so successful interactive simulations need
to obey the mathematical relationships of fluid dynamics with high
spatial resolution and fast temporal response. In this work we propose
an innovative GPU-based approach that enables real-time haptic
rendering of high-resolution 3D Navier-Stokes fluids. We show
that moving the vast majority of the computation to the GPU allows
for the simulation of touchable fluids at resolutions and frame rates
that are significantly higher than any other recent real-time methods
without a need for pre-computations. Based on our proposed
approach, we build a haptic and graphic rendering system that allows
users to interact with 3D virtual smoke in real time through
the Novint Falcon, a commercially-available haptic device.

hopefully next generation games will use this
