Modeling of Volcanic Clouds using CML

In this paper, the model of volcanic clouds for computer graphics using the Coupled Map Lattice (CML) method is proposed. In this model, the Navier-Stokes equations are used, and the equations are solved by using the CML method that can be applied as an efficient fluid solver. Moreover, to generate desired shape of volcanic clouds, some parameters that allow intuitively control of the shape are provided. Hence, in this system, the behavior of the volcanic clouds can be calculated in practical calculation time, and by only changing some parameters various shapes of the volcanic clouds can be generated. Therefore, photo-realistic images/animations of various shapes of volcanic clouds can be created efficiently by the proposed approach.
