Research Progress on Simulation of Deformable Objects Using Finite Elements Model

Nowadays the simulation of deformable objects is a hotspot in the field of computer graphics. In the simulation of operation, for the request of precision, Finite Elements Models (FEM) is the best model. The disadvantage of FEM is the mass quantity of the calculation. To solve this, many new techniques has come out recently. To summarize these new FEM techniques, including their thoughts and the solutions, it will be helpful to the researchers who want to use FEM to do some simulation work.
