Real-time Gaseous Phenomena - A Phenomenological Approach to Interactive Smoke and Steam

摘要

In this paper we present a novel approach to the simulation of interactive gaseous phenomena. Our main emphasis is put on real-time simulation and the visual correct interaction of the gas with inserted objects. In contrast to methods based on the numerical solution of physics-based models, such as Navier Stokes or Euler equations, we propose a phenomenological approach in which we combine the speed and flexibility of particle simulations with the visual quality of stochastic fractals. This approach especially meets the requirements of interactive simulations as they are found in virtual reality environments.
