A Differentiable Material Point Method Framework for Shape Morphing
Michael Xu, Chang-Yong Song, David I. W. Levin +1
We present a novel, physically-based morphing technique for elastic shapes, leveraging the differentiable material point method (MPM) with space-time control through per-particle d…
