What Is Injective Deformation Processing in Physics Simulations?

TL;DR

Injective deformation processing is a new technique that enables realistic physics simulations with significant geometry changes without overlap or inside-out issues. It can also repair flawed simulations, producing natural movements. Simulations using this method range from half a second to 12 minutes per frame, depending on the complexity of the deformation.

Dear Fellow Scholars, this is Two Minute  Papers with Dr. Károly Zsolnai-Fehér. Today, we are going to absolutely destroy  this virtual bunny. And then, inflate this cat   until it becomes… a bit of a chonker. And, I hope  you like dumplings, because we’ll also be able to   start a cooking show in a virtual world. For  instance, we can now squash a... Read More
