Efficient Simulation of Water Puddle

In this paper a method is proposed to efficiently simulate water puddle on a plane. At first a particle-based fluid simulator is run on a plane. Then the 2D fluid contour is extracted and its enclosed region is discretized, inside which a minimization problem is solved to build the puddle surface. With reasonable simulation domain the puddle can be animated interactively in real time. Several experimental results demonstrate the realistic results.
