FlexHopper: Particles clean

“

- [Instructor] Welcome. I have my exercise file open already. In the last video we started looking at the FlexHopper plugin and experimenting with the particle physics simulator and testing out how air could flow within constraint space like a room. So if we show this running, I can see I have these particles that are filling up this room type space. So let's look at how we could simulate the process of sanitizing air within a space. So here I have the particles coming out of FlexHopper. So what I want to do is track their status in some way. So imagine there are, you know, UVC sanitizing lights along the top of the room, something that some hospitals or other spaces are doing. So if I go here to deconstruct point, plug the points in, now I'm getting a Z vector for each point. And I can simply say if the Z vector is greater than some value, so let's say greater than 20, I think the room is set up to have a height of 24,…
