The simulation of fluid phenomena, such as smoke, water, fire, has developed rapidly in computer games, special effects, and animation. The various physics-based methods can result in high quality images. However, the simulation speed is also important issue for consideration in applications. This paper describes an efficient method for controlling smoke simulation, running entirely on the GPU. Our interest is in how to reach given user-defined target smoke states in real time. Given an initial smoke state, we propose to simulate the smoke towards a special target state. This control is made by adding special external force terms to the standard flow equation.
