Efficient multiple source smoke scene representation using cache data

Abstract

This paper focuses on the representation of smoke, which is computationally expensive, and proposes a method for representing large-scale smoke scenes that requires a minimum of computation. Based on a previous study in which multiple smoke cache data were placed by a creator in 3D space to generate a large cumulus cloud, the area where the cache data overlap is set as a new emitter and recalculated using the Euler equation with the velocity field and density stored in the cache data. This enables the representation of smoke mixing with other smoke while using cache data. In addition, as a large-scale smoke representation using cache data, a simulation of a large sandstorm approaching is performed.
