Interpolations of Smoke and Liquid Simulations

Nils Thuerey
2016 ACM Transactions on Graphics  
We present a novel method to interpolate smoke and liquid simulations in order to perform data-driven fluid simulations.  ...  As a result, we can interpolate swirling smoke clouds, and splashing liquid simulations.  ...  For a liquid simulation, we simply use the surface of the liquid phase, and for a smoke simulation we use an iso-level of the density volume (details will be given in Section 7).  ...

A Semi-Lagrangian CIP Fluid Solver without Dimensional Splitting

Doyub Kim, Oh-young Song, Hyeong-Seok Ko
2008 Computer graphics forum (Print)  
In this paper, we propose a new constrained interpolation profile (CIP) method that is stable and accurate but requires less amount of computation compared to existing CIP-based solvers.  ...  These advantageous features of CIP are, however, diluted by the following two shortcomings: (1) CIP contains a defect in the utilization of the grid data, which makes the method suitable only for simulations  ...  Although the pseudo-code does not include the density or level set implementation, it is straightforward to extend it to smoke or liquid simulator.  ...
