|Title: ||Editing explosion simulations|
|Authors: ||Fong, Heung Wah|
|Issue Date: ||2004 |
|Abstract: ||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.|
