Interaction with fluids is very frequent in our everyday lives (as an example, when we stir a cup of coffee in the morning). This research arises in order to allow users to interact with virtual fluids through an haptic device as well as an interaction with virtual rigid or deformable objects. A haptic simulation usually needs updating rates about 1 KHz. That’s why it is necessary to find a method to make the computation of the force perceived by the human operator as fast as possible. In addition to the force computation, this research is involved in studying in-depth strategies for the graphic updating too. Although the graphic updating requires rates of 30-60 Hz, it is hard to realize an effective real-time simulation. The reason is that the fluid dynamics is represented by the Navier-Stokes equations and it is difficult to solve this set of equations in real-time and with a high accuracy. Indeed a high accuracy corresponds to a high computational complexity. It is not to be omitted that a virtual fluid simulation, able to follow closely the reality, could be used to make better current medical systems, where the interaction with deformable bodies and viscous substances could lead to a larger and larger number of feasible applications.
