Overview
This paper presented a method for controlling animated smoke. Given a sequence of target smoke states, the method generates a smoke simulation in which the smoke is driven towards each of these targets, matching the target's shape. This is very similar to the Shi and Yu 2005 paper on Controllable Smoke Animation With Guiding Objects except on the method of maintaining the shape of the smoke and preventing the smoke from diffusing.
This paper's method consists of a driving force term that causes the fluid to carry the smoke towards a particular target, and a smoke gathering term that prevents the smoke from diffusing too much. However, the gathering term creates defects while the smoke is gathering.
Although the smoke is driven towards the target shape, there is no control over its quality and intermediate shape. Instead, the animator is provided with several parameters for controlling the rate at which smoke evolves, as well as other characteristics of the simulation.
