Abstract:

This paper presents scalable solutions for achieving virtual humans who are able to manipulate objects in interactive virtual environments. The scalability trades computational time with the ability to address increasingly difficult constraints. In time-critical environments, arm motions are computed in a few milliseconds using fast analytical Inverse Kinematics. For other types of applications in which collision-free motions are required, a randomized motion planner capable of generating motions of average complexity in approximately a second of computation time is employed. The steps required for defining and computing different types of manipulations are described in this paper.
