McAdams et al, ACM SIGGRAPH 2011

We present a new algorithm for near-interactive simulation of skeleton driven, high resolution elasticity models. Our methodology is used for soft tissue deformation in character animation. The algorithm is based on a novel discretization of corotational elasticity over a hexahedral lattice. Within this framework we enforce positive definiteness of the stiffness matrix to allow efficient quasistatics and dynamics. In addition, we present a multigrid method
that converges with very high efficiency. Our design targets performance through parallelism using a fully vectorized and branch-free SVD algorithm as well as a stable one-point quadrature scheme. Since body collisions, self collisions and soft-constraints are necessary for real-world examples, we present a simple framework for enforcing them. The whole approach is demonstrated in an end-to end production-level character skinning system.

Youtube wont let me post the link, but the paper name is

Efficient elasticity for character skinning with contact and collisions

wow looks great

I'd love to see some of the underlying algorithms! =)

Really great. I wonder how much more processing power is needed to do this in realtime games like beat em ups.

Hands are always the most awkward looking to me in 3D characters. This fixes it entirely. I hope I get to use this soon. I feel like this is the way to go.

Any thoughts on how it would enter into the real-time gaming workflow?
