Particle SOP in TouchDesigner – Interactive Metaball Forces and Surface Attractors

Use the built-in power of TouchDesigner by leveraging the Particle SOP for quick, easy interactive particle systems. In this tutorial we will take a tour of the Particle SOP, then focus on using Metaball and Force SOPs, along with the Point SOP to precisely manipulate our geometry attributes.

Use the mouse and Panel CHOP to add quick interactivity, easily extensible to other inputs like LiDAR or Kinect sensors. I hope you enjoy!
