ABSTRACT 

Realistic Fluid Animation is an inherent part of special effects in Film and Gaming Industry. These animations are created through the simulation of highly compute intensive fluid model. The computations involved in execution of fluid model emphasize the need of high performance parallel system to achieve the real time animation. This paper primarily devoted to the formalization of parallel algorithms for fluid animation employing Smoothed Particle Hydrodynamics (SPH) model on Compute Unified Device Architecture (CUDA). We have demonstrated a considerable execution speedup on CUDA as compare to CPU. The speedup is further improved by reducing complexity of SPH computations from O(N 2 ) to O(N) by utilizing spatial grid based particle neighbour lookup.
