Klar, GergelyKaterina Mania and Eric Reinhard2015-07-132015-07-132008https://doi.org/10.2312/egs.20081038In this paper we present a framework to simulate visually plausible large scale flow of fluids or smoke. To maintain real-time speed, we define the simulation over a coarse grid which is refined with a more detailed grid at places where fine details may emerge, like around moving obstacles. The detailed grids also act as fixed frames of reference to the surrounded obstacles to prevent the need for working with moving boundaries in the flow.10.2312/egs.20081038127-130
