Tutorial
In this tutorial, we use the Ray POP to make particles bounce off specific collision objects across two different examples. Get the project file: https://www.patreon.com/posts/tutorial-with-156434499

Tutorial
In this tutorial we create a component which can detect when objects are on top of each other (colliding). This works for any 2D input with alpha. You could also render a 3D scene and use it there, it just works on the u v axis though.
2D Collision Detection

Hi there, I've made a new example how to build a particle system using a compute shader in TouchDesigner. This one is based on instancing and uses a heightmap for the particle to collide with. I tried to explain everything as much as possible using little textDATs docked to most components.
