Abstract:
1. A method of operating a display system having a display, a processing unit, and a memory, the method adapted to display an animation of n objects subject to motion in m constrained degrees of freedom on the display and comprising: defining and storing system parameters in memory, wherein the system parameters define a plurality of objects and at least one constraint acting upon an object in the plurality of objects; incrementing a time step; after incrementing the time step, calculating updated system parameters in the processing unit using a projected iterative descent method applied to one or more Linear Complementarity Problems (LCP) defined in relation to the system parameters, wherein the projected iterative descent mettnod comprises a step of testing for termination; and, wherein the animated motion of the objects is determined in relation to the updated system parameters.
