Namespaces
namespace	SimTK
	This is the top-level SimTK namespace into which all SimTK names are placed to avoid collision with other symbols.
Functions
SpatialVec	findRelativeVelocity (const Transform &X_FA, const SpatialVec &V_FA, const Transform &X_FB, const SpatialVec &V_FB)
	Find the relative spatial velocity between two frames A and B whose individual spatial velocities are known with respect to a third frame F, with the result returned in A.
SpatialVec	findRelativeVelocityInF (const Vec3 &p_AB_F, const SpatialVec &V_FA, const SpatialVec &V_FB)
	Find the relative spatial velocity between two frames A and B whose individual spatial velocities are known in a third frame F, but leave the result in F.
SpatialVec	reverseRelativeVelocity (const Transform &X_AB, const SpatialVec &V_AB)
	Given the relative velocity of frame B in frame A, reverse that to give the relative velocity of frame A in B.
SpatialVec	reverseRelativeVelocityInA (const Transform &X_AB, const SpatialVec &V_AB)
	Given the relative velocity of frame B in frame A, reverse that to give the relative velocity of frame A in B, but leave the result expressed in frame A.
SpatialVec	shiftVelocityBy (const SpatialVec &V_AB, const Vec3 &r_A)
	Shift a relative spatial velocity measured at some point to that same relative spatial quantity but measured at a new point given by an offset from the old one.
SpatialVec	shiftVelocityFromTo (const SpatialVec &V_A_BP, const Vec3 &fromP_A, const Vec3 &toQ_A)
	Shift a relative spatial velocity measured at some point P to that same relative spatial quantity but measured at a new point Q given the points P and Q.
SpatialVec	shiftForceBy (const SpatialVec &F_AP, const Vec3 &r_A)
	Shift a spatial force applied at some point of a body to that same spatial force applied at a new point given by an offset from the old one.
SpatialVec	shiftForceFromTo (const SpatialVec &F_AP, const Vec3 &fromP_A, const Vec3 &toQ_A)
	Shift a spatial force applied at some point P of a body to that same spatial force applied at a new point Q, given P and Q.
