Fast Algorithm Based on Particle System for Simulating 3D Dynamic Clouds

TL;DR: It is proved that the proposed fast 3D cloud simulation algorithm can produce shapes of 3D clouds quickly and really by several experiments, at the same time the algorithm can implement the dynamic simulation of clouds.

Abstract: A fast 3D cloud simulation algorithm based on particle system was proposed. It used the given several spheres to simulate the outline of clouds and determined the bounding box of cloud particles. Then the particles were judged whether they were part of cloud particles by comparing the position relationship between particles and spheres. Finally, rendering and drawing cloud particles to realize 3D simulation of clouds. As particles kept moving, so it was need to update attributes of particles at internals. If the particles moved out of the spheres, they should be deleted. By simulating the movement of particles, the method implemented the simulation of the motion of clouds. At last, it proves that the method can produce shapes of 3D clouds quickly and really by several experiments, at the same time the algorithm can implement the dynamic simulation of clouds.
