Controlling Explosion Simulations by Estimating the Optimal Initial Intensity Distribution and Predicting Control

Abstract

Recently, many methods for simulating natural phenomena on the basis of fluid simulation have been proposed. A method for simulating explosions was also proposed, but the shapes of the simulated explosions depend on many simulation parameters. Therefore, creating the desired shape for an explosion as specified by the user is difficult. In this paper, we propose a method for controlling explosion simulations in order to form the desired shapes. Our method optimizes the initial intensity distribution of an explosion and controls the simulation to minimize the difference between the target shape and the shape of the simulated explosion. We use a predictive approach to control the explosion simulation accurately. Using the proposed method, animations of explosions controlled into specified shapes can be generated.
