As far as I know, corotational fem (stiffness warping) is the state of the art of real-time FEM, so the two resources seem suitable although they don't cover collision detection properly. The same method is also described in the paper about Pixelux DMM here: http://graphics.cs.berkeley.edu/papers/ ... TD-2009-08
In case someone missed it, I recently posted a link to source code of working FEM under the permissive Zlib license, extracted from the OpenTissue framework here
The SOFA framework is showing real-time corotational FEM running on the GPU. They can simulate 45k tetrahedra in real-time (90FPS) on the most recent NVIDIA GPUs.

The upcoming GPU Computing Gems Jade edition
has a chapter on this.
