| Abstract;In this paper, a modified particle system is proposed for generating cloud in a three-dimension. In the proposed method, initial position of each particle is set by Gaussian Distribution. Therefore, the particle range to be able to consist is control by Gaussian distribution limit in a three-dimension. Next, each particle is moved according to buoyancy, the force of interaction between particles, and the repulsive force the particle receives from the atmosphere. The buoyancy is dependent on the relationship between temperature, atmospheric pressure, and air density. When a particle is beyond the range to control, or a particle life run out, the particle is disappeared. The model of cloud is set by some particle group. At the result, the method can represent the cloud at real near time. (author abst.) |
