Collision detection for fountain model based on partical system

In this paper, we consider the advantage of particle system to simulate the real-time fountain model, and make use of the Possion distribution to get the probability of the special number of the particles which collision happened and the average number of particles which the collision play out. In addition, we present a new approach from the perspective of the energy of the particles to judge whether the collision occur between the water droplet particles and the obstacles. The simulation result show that the algorithm is simple to achieve. At the same time, our algorithm accelerated the process of collision detection.
