Physically based Animation of Tongue of Fire
基于物理模型的火苗动画

In this paper, a physically based approach for simulating Tongue of Fire is proposed. Realistic animation and real-time simulation are two objectivespursued in computer graphics applications. Traditional animation technique can obtain virtual movement, but it has difficulty for realistic movement. Compared with the traditional animation technique, physically based animation can represent realistic movement better. The inviscid and incompressible Euler equations are used in the model, and the operator splitting method is employed to split the model into external force term, advection term and projection term. Every step is stable, so the whole process is also stable. Thus, the big time step can be taken to ensure real-time simulation. Compared with the traditional technique, this method can be taken for realistic animation and real-time simulation of Tongue of Fire in computer graphics applications.
