Editing explosion simulations

Authors Fong, Heung Wah
Issue Date 2004
Summary Explosion effects are widely used in movies and the game industry. Popular methods in computer graphics synthesize these effects by computing a velocity and temperature field based on fluid dynamics, such that smoke and fire behave realistically. In this kind of physics- based simulation, long computation time and accurate setting of parameters are generally required in order to obtain a desirable result. Due to this restriction, it is usually difficult for the animator to control and model a particular explosion. This thesis illustrates a straight-forward method for editing physics-based explosions. Rather than controlling an explosion's behavior via simulation parameters and external forces, we allow the user to directly warp the flow-field and temperature values computed by an initial simulation. A particle-system is then played back through the altered simulation to produce a new explosion that reflects the look and behavior specified by the user. This simple approach provides a flexible method to edit and author convincing explosions that are otherwise difficult to predict and control.
