Adding detail and small curls with Vorticity

- So let's take a look at the vorticity settings underneath the simulation tab next. So if we twirl down the vorticity menu, we can see I've just got to put a value in here. I'm just going to exaggerate this by putting a higher value in of 20, and I'm going to fire up the interactive simulation here, and we can see it gets fairly crazy pretty quick. So what vorticity does it takes the fine detail and small curls in your simulation and basically amplifies them over time. You've got to be careful because if you have the value too high it can get really noisy really quickly. Obviously, this is for demonstration purposes, so that's what we want to see here to get an idea of how it works. One thing we can notice here too is it's really even across the entire fluid. So sometimes you need more control than that, you might want it to only kick in when a temperature is high, or low, or just at a different point in the fluid's life. So we can actually do that over here if we use this intensity…
