The simulation of fluids in computer graphics is an incredibly complex and interesting topic, and one that has the potential to generate some equally impressive and beautiful outcomes. Across the web, many such techniques originating in academic papers, have been translated into shader languages and further experimented with. In this video, Jack DiLaura walks you through creating a generative liquid painting effect in TouchDesigner, which adapts a GLSL shader containing fluid simulation techniques for use in TouchDesigner. You’ll look at the basics of converting shaders from Shadertoy, a popular platform for creating and sharing shaders, to be used within TouchDesigner, along with tools in TouchDesigner to add interactivity and further aesthetic exploration to the original effect.
