Movement and deformation of virtual object based on argument passing method

Force feedback is a good opportunity for virtual reality technology (VRT) into the field of engineering simulation. Haptic device point (HIP) is the common tool used for interacting with the virtual objects, while the mass-spring model consistent with which does not have good scalability, and cannot guarantee the necessary accuracy. By substituting mass-spring model with finite element model (FEM) for contact problems, there will be a solution. This article has set up a system based on argument passing between virtual reality environment and FEM solver, and details the system working process and the challenge.
