Class SimTK::Force::MobilityLinearSpring

This is not meaningful unless the mobilizer coordinates are defined such that qdot=u. In particular, do not use this on coordinates for Ball or Free mobilizers. You can often replace those with Gimbal or Bushing mobilizers for which qdot=u holds, or split up the mobilizer into simpler components separated by massless bodies.

Class SimTK::Force::MobilityLinearStop

MobilityLinearStop currently works only for coordinates q whose time derivatives qdot are just the corresponding generalized speed u. That is the case for translational mobilities, pin, universal, and gimbal mobilizers but not free or ball mobilizers.

Class SimTK::Pathname

Eliminating ".." segments textually can cause them to behave incorrectly in the presence of symbolic links. These should probably be left in place with evaluation deferred.

Class SimTK::Measure_< T >::Delay

Only linear interpolation implemented so far.

There should be an option for the measure to specify a sampling interval that would force the integrator to provide interpolated states at least that often.

The current implementation involves a lot of unnecessary copying because it uses an auto-update state variable and cache entry. It should be using an end-of-step event handler to update the buffer directly in the state.

Member SimTK::Geo::BicubicBezierPatch_< P >::calcBoundingSphere () const

Currently we use the fact that the patch is enclosed within the convex hull of its control points and generate the minimum bounding sphere that includes all control points; that is not necessarily the tightest-fitting sphere.

Member SimTK::Geo::BicubicBezierPatch_< P >::calcAxisAlignedBoundingBox () const

Currently we use the fact that the patch is enclosed within the convex hull of its control points and generate the minimum bounding box that includes all control points; that is not necessarily the tightest-fitting box.

Member SimTK::Geo::BicubicBezierPatch_< P >::calcOrientedBoundingBox () const

Currently we use the fact that the patch is enclosed within the convex hull of its control points and generate an oriented bounding box that includes all control points; that is not necessarily the tightest-fitting box.
