Coding Challenge 132: Implementing Real-Time Fluid Simulation in Processing

In this video, I follow Mike Ash’s guide to Fluid Simulation and port Jos Stam’s "Real-Time Fluid Dynamics for Games" algorithm and code in Processing (Java). Code: https://thecodingtrain.com/challenges/132-fluid-simulation
