    Production ready MPM simulations



    We present two complementary techniques for Material Point Method (MPM) based simulations to improve their performance and to allow for fine-grained artistic control. Our entirely GPU-based solver is able perform up to five times faster than its multithreaded CPU counterpart as a result of our novel particle and grid transfer algorithms. On top of this, we introduce Adaptive Particle Activation, that both makes it possible to simulate only a reduced number of particles, and to give artists means for fine direction over the simulation.
