Physically Based Simulation of Smoke in Real-time

In this paper, a physically based approach for real-time numerical smoke simulation is proposed. Realistic animation and real-time simulation are two objectives pursued 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 smoke in computer graphics applications.
