Animating smoke with dynamic balance
نویسندگان
چکیده
We propose a numerical method for maintaining a dynamic rolling motion of animated gaseous phenomena, such as smoke, that avoids dissipation due to numerical error. We compensate for the errors induced by a semi-Lagrangian scheme using an error estimate for each time interval. We develop a new advection term and perform vortex advection based on a vorticity confinement force. Example simulations show that this method is able to keep smoke features alive, even near the center of a vortex. Copyright# 2005 John Wiley & Sons, Ltd.

Chapter 4: Procedural Modeling and Animation of Gases and Fluids
This chapter describes modeling and animating procedural gases, liquids, and textures. Volume density functions are being used extensively in computer graphics for modeling and animating gases, fire, fur, liquids, and other ‘‘soft’’ objects. I have used them extensively for modeling and animating gases such as steam and fog [2, 5, 4, 3]. Hypertextures [16], metaballs [20](also called implicit s...
