Real-Time Simulation of 3D Smoke Based on Navier-Stokes Equation

摘要

In this paper, we investigate the fluid simulation on GPU, and implement real time smoke animation based on GPU by numerically solving Navier-Stokes equation. Based on Navier-Stokes equation, we discuss the details of the method, "Stable Fluids". This scheme makes implementation on the GPU simple, because there is a straightforward mapping between grid cells and voxels in a 3D texture. After optimizing, this method not only fit to GPU, but also is steady and realistic greatly.
