  abstract =     "We describe a simple and fast method of creating and
                 using joint sinus reach cones to limit the range of
                 motion on universal and ball-and-socket joints. Reach
                 cones can be created interactively or based on results
                 from biomechanics. A reach cone is specified as a
                 spherical polygon on the surface of a reach sphere that
                 defines all positions the longitudinal segment axis
                 beyond the joint can take. Reach polygons can be
                 concave or convex, and cover more than one hemisphere.
                 Longitudinal axis rotation limits can also be defined
                 for locations in the reach cone. Calculations to
                 determine whether a segment is within the reach cone
                 are based on the relation of the segment longitudinal
                 axis to the planes defining the reach cone and are done
                 in the local coordinate space of the segment. The
                 calculations have no discernible effect on the speed of
                 interactive display or animation.",
