In this paper we describe the parallelization of an unconditional stable solution scheme of the Navier Stokes equation which is suitable for animation purposes. Profiting from its unconditional stability we are able to use simulation time steps which are larger than the animation timesteps and interpolate between them. Furthermore we present additional improvements in the visualization quality of the simulated output by using fractal textures in the 3D texture renderer post process for optical refinement using the scalar and vector fields as input parameters Our technique facilitate real-time animation rates of several examples on current multi-processor workstations and PC's.
