| Abstract;Plume fluid, such as continuously growing smoke or a cloud with an expansive gush, is a difficult phenomenon to represent with a high level of reality. The methods that have been proposed so far are more for representing volcanic smoke or a cumulonimbus cloud. In this paper, we propose a method for animating plume fluid. This method uses particle generators that are continually provided in the simulation space to generate particles recursively. This scheme efficiently represents the characteristic expansion phenomenon of plume fluid. In the model presented in this paper, the motions of particles are determined by a particle-based simulation method which approximately realizes the pressure gradient, viscosity, buoyancy, entrainment, adiabatic cooling, and release of latent heat of a fluid represented as cumulus.
