Many virtual reality-based applications involve simulations of micro-structures such as hair, fibers and textile yarns, as well as ropes, flexible wires and tubes. In virtual surgery, for example, flexible wires and tubes are common medical instruments and devices. Core to the simulations is the robust physics-based computation of elastic rods. In this paper, we present a volumetric finite element based approach to simulating rod-like objects with real-time performance suitable for interactive virtual environments. A sequence of Cosserat joints (tiny volumetric elastic joints) linked by rigid bar segments are used to compute the elastic rod objects. By construction, each of the joints is equipped with its own mass, degrees of freedom (DOFs) with a small volumetric deformation field to measure deformation energies due to stretching, shearing, bending, and twisting about the centerline curve of the long flexible object. Therefore, a generalized continuum formulation is derived to compute both bending and twisting deformations of elastic rods, resulting a simple and general simulation model to facilitate efficient physics computations, whereas conversional simulation methods for elastic rods require explicitly decoupling between bending and twisting deformations. In this paper, we show simulations of a wide range of object behaviors for interactive virtual reality applications. |
