The Research Of Smoke Simulation And Rendering Based On Shape Controlling

In recent years physically based fluid simulation is becoming a hot research issue in computer animation. This article realizes smock simulation and rendering combining computational fluid dynamics and computer graphics. For controlling smoke's shape, the shape controlling force is increased on the foundation of smoke freedom movement set. Smock physical model equations are expressed by way of Navier-Stocks equation and settled numerical compute method. Then, smock density filed data is formed and it will be changed screen image using volume rendering.This paper designs smock control parameter calculation and smoke render system. Smoke simulation animation is generated in which smock forms fixed shape gradually after people put some smock's shape in the system.
