Abstract :
This research proposes a novel method to generate 3D cloud, usually appeared in 3D weather visualization system, from the satellite cloud image. First, the satellite image will be separated into several layers by classifying the image´s pixel intensity, and then the authors will generate 3D cloud with the creating rule of Cellular Automata (CA) considered by the presence of neighboring pixels. In this study, an interpolation method for animating cloud particles including transport and collision is also proposed. The authors try to develop a method which uses to transport the generated cloud particles from the beginning to the ending of time interval. Finding the direction to move a particle, we compare the increased and decreased value from time to time of which one position value and its neighboring values. We use a rule of collision based on Lattice Gas Cellular Automata (LGCA) in collision state. The example of 3D cloud generation is also shown in this paper.
