Abstract

We describe a novel method for efficiently controlling the smoke's shape. Given a moving object's shape sequence represented by a geometric model sequence, our method can generate a simulation in which smoke flows out somewhere and quickly forms shapes in sequence. It looks like a cloud of moving smoke that maintains fundamentally the object shapes and the fluid-like behavior. By adding two control forces to the physics-based free flow, the smoke shape can be controlled well while flowing. In our system, the free flow and the shape-controlled flow can be easily switched to each other. The additional computation to controlling the shape is negligible compared with the free flow, and is less than that of previous work. Copyright © 2007 John Wiley & Sons, Ltd.
