Particle source object overview

“

- [Instructor] Now we'll take a look inside this particle source geometry object I've provided for you. So with this project unlike some of the other ones where we were basically deriving points off existing moving geometry, with this one, here let me do a ghost other object, so we can see. We've got our little kind of volcano-y structure. And I basically just created a circle, scattered some points on it, defined some up and normal vectors with a little attribute expression sop here and then I'm going to visualize those so you can see what's going on. I'm gonna turn on normals, I'm gonna hit d to go to our visualizers and turn on our up vectors. Now I'm gonna turn off ghost all objects. Okay so you can see that we just have ups going up and normals pointing in one direction. I created a little point stop that just rotates these around randomly so we have normals and ups that are perpendicular to each other but that are just rotated around. Because we're gonna be instancing geometry…
