Create a point deform system
- [Narrator] Now we're going to take a look at properly preparing the geometry that we feed into our simulation. Because as we discussed in the last video, we can't have geometry with a changing point count running into the finite element solver. But we need this triangulated version of geometry that this solid embed node is kicking out, so we're going to look at a technique to do this right. Firstly I'm going to click on the solid embed and I'm going to change the element's scale to point one. That's just going to give us a higher resolution starting point here. Going to take a little while to compute, as you can imagine, also we wouldn't want to be doing this process every frame, even if it worked, because we're taking all this time doing this re-meshing inside of here, which is not something we want to do on a frame-by-frame basis. So what we're going to do, once this kicks out, and you can see now that we have a higher resolution proxy triangulated mesh here. I'm going to put down…
