The numerical scheme is based on a family of schemes called geometric or discrete variational integrators guaranteeing that the momentum and energy are exactly conserved over long periods of time for conservative systems. Besides, we report on an efficient numerical procedure to handle the inextensibility of the thread through physically based Lagrange multipliers, as well as the internal dissipation of the thread. We have performed simulations to verify the capabilities of our model to conserve momentum and energy, accurately calculate the axial constraint forces along the thread for haptic feedback, and capture bending-torsion coupling leading to the formation of plectonemes. While many of the ideas are well known in the computer graphics community (especially in hair modeling), we have implemented several improvements for the specific purpose of speeding up the computations for developing physically based haptic interfaces for knot tying and suturing.

the finger motions of a character playing a guitar by first building a motion capture database of hand configurations, and then, given a (sometimes partially specified) desired hand configuration, running the K-Nearest-Neighbors algorithm to search for the closest physically attainable configuration.Simply interpolating the data cannot produce highly detailed motion of the skin, such as buckling, and also suffers from some well-known artifacts, such as the collapse of volume around joints.The two approaches below remedy these problems.Abstract：This is a short survey of musculoskeletal hand models in computer graphics. We review a number of simulation models under six categories: example-based, passive muscles, joint torques, moment arms, dynamic strands, and volumetric.

A nonlinear physical simulation is presented involving the soft body deformation and interaction contacts. We demonstrate the finite element method relying on Lagrangian discretization to simulate the deformation of the soft body with hyperelastic material properties. To perform a stable simulation, we use the constrained Delaunay Tetrahedralization to resampling and remeshing the object. A new contact strategy is developed and used to replace the collision detection. This method does not need to iteratively achieve the optimal contact response on the constrained boundary. It can dynamically determine whether the contact status of the point should be in a static or a sliding friction mode. The explicit method for the finite element model is employed in order to perform all the steps of the algorithm on the GPUs and achieve a real-time simulation.
