Interactive Control of Fire Simulation based on Computational Fluid Dynamics.

Visual simulation of fire plays an important role in many applications, such as movies and computer games. In these applications, artists are often requested to synthesize realistic fire with a particular behavior. This paper presents two methods in order to help artists meet such requirements. First, we propose a method for controlling fire simulation by extending a previous method for smoke simulation. Controlling fire simulation with the previous method is difficult because of strong buoyancy forces caused by high-temperature. To address this problem, our method locally adjusts magnitudes of control forces. Second, we present an interactive editing method for external force field. The user can interactively design the shape of fire by placing a set of control points. Our method generates a force field to form the shape of the fire. Experimental results show that our method can control the fire into an arbitrary shape specified by the user.
