T Temperature field

Based on earlier presented solvers for the incompressible Navier-Stokes equations, we implement a 3D fluid solver. The solver works in a few simple steps implemented in fragment shaders running entirely on the Graphic Processing Unit (GPU) of a modern graphics card. We present a simple visualization approach for rendering high-quality smoke animations in real-time. Finally, to handle interaction between fluid and stationary objects, we present a simple method for setting boundary conditions
