Particle systems are a popular and often-requested topic among interactive developers. Their high level of configurability and captivating movement patterns make them a fun effect to experiment with. TouchDesigner has a couple of methods for working with particles, including particlesGPU, which is a GPU-based simulation that allows for a high level of particles without sacrificing performance.

In this video, Jack DiLaura walks you through the basics of the particlesGPU component. You’ll learn how to set up geometry for use with the system, how to work with basic forces, add color via a texture, how to use a 2D texture array to apply different textures to different particles, and more.

This tutorial is highly recommended for users new to particlesGPU who want to try out some of the functionality it has to offer!
