Part 7/9:
The core of water simulation techniques lies in the principles of fluid dynamics, particularly as articulated by the Navier-Stokes equations. At its essence, water simulation operates through particle-based models combined with smoke simulations—since these systems manage fluid pressure effectively. However, high-quality results demand an immense amount of computational resources and time, evidenced by the staggering storage needs illustrated with the simulation data from films like Kingdom of the Planet of the Apes.
