Real-Time Simulation of 3D Smoke on GPU

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.
