Reactive particle systems are always in demand by clients and are extremely fun for audiences. In TouchDesigner, we can create a fully reactive GPU particle system with just a handful of nodes in less than 10 minutes.
In this tutorial we look at how to create a basic interactive particle system by using the Kinect v2 (works with Azure too), Optical Flow and particlesGPU. We especially have a closer look at the particlesGPU, so you can easily customize the look and behaviour of the particles to your needs.
Hello, I share a new Touchdesigner tutorial Particle system generated from body movement, using the difference between frames technique, can be used with a web camera, kinect sensors, etc.
Hi! The idea behind this tutorial is somewhat similar to my older particles on 3D SDF, but instead of mathematically describing 3D geometry with sign distance function, here we using difference in brightness of 2D texture to calculate particle velocities.
