If you wish to understand and implement a simple, real-time fluid simulator, you can check out my thesis here. It runs on your GPU and comes with source code:

Ryan Guy's notes on their FLIP Fluids implementation differences from the paper:
- The paper mentions gathering data from nearby particles in some calculations. Our simulator does not perform a nearest-neighbour particle search so we've made some modifications to to avoid this search.
- Our whitewater generator uses the Signed Distance Field (SDF) of the liquid surface to derive the surface curvature for locating wavecrests.
- The SDF is also used to test the depth of the particles, such as if they are located inside or outside of the liquid volume.
- Instead of using the particles to calculate velocity difference (trapped air potential), we are using velocity values that are stored on the grid.
