POP Collision Detect

“

- [Instructor] Now we're gonna add in the ground collision for these particles, because that's a big part of a simulation like this because we have this emission happening, but we want to have those actually impact the ground. Let me go up a level back to our objects and we're gonna take a look inside our ground geometry object here. I've created just a piece of simple ground geometry using the new height field stuff in Houdini 16, and I've cashed out just a polygonal piece of geometry for you. You can see down here, kind of like we had in our object network, there's a bunch of different things going on because I basically have a bunch of different versions of this geometry for different purposes. Under our out node here, this is just our render-able geometry, this is just a simple plane of noise basically. There's our ground, but then I've also just threw a few other sop nodes, created this out for particle collision, where we have created an object with some thickness that we need…
