Foamy Waves with NVIDIA Flex in TouchDesigner

NVIDIA Flex is a particle-based physics simulator that takes advantage of NVIDIA GPUs to generate high-performing particle and fluid simulations. It comes integrated in TouchDesigner and provides a GPU-enhanced alternative to some of its other particle and physics simulation options. A feature-packed tool, it can often be a little daunting for beginners to navigate its many parameters. In this tutorial, Jack DiLaura walks you through building a simulation of foamy waves using NVIDIA Flex. You’ll learn how to utilize the data from NVIDIA Flex for instancing geometry, work with diffuse particles to generate a sea foam-like effect, take a look at the many Flex parameters and how they can impact the simulation, along with applying external force to the particles.
