In this TouchDesigner tutorial I’ll show you how to take the particle cloud input from a Kinect V2, filter out the points you don’t want, and add color and movement effects.

I’ve tried doing this in TouchDesigner for years and have finally figured it out. In this tutorial, you’ll learn how to create a particle effect that combines all three forces a flocking algorithm requires: attract, repel, and follow. https://youtu.be/c7WElrDCHzg

You'll learn how to create a light painting installation in TouchDesigner in this tutorial with Marco. By isolating the brightest spots of an input video or webcam feed and turning them into a geometry with the TraceSOP, you can then add particle systems along the way.

This is an Interactive Digital Energy Field modified according to the hand's motion which is tracked through AI integrated into Touchdesigner. I have designed a project that is integrated with MEDIAPIPE Hand tracking to control Nvidea Flex Solver generative particle system + sliders for additional

Jack DiLaura walks you through using the Body Track CHOP to create a cool particle system effect that follows users detected in a video or camera feed.
