Detailed Description

Solve for the coordinates (degrees of freedom) of the model that satisfy the set of constraints imposed on the model and the set of desired coordinate values.

The InverseKinematicsSolver provides the option to convert the problem to an approximate one where the constraint violations are treated as penalties to be minimized rather than strictly enforced. This can speed up the solution and can be used to seed the constrained problem closer to the solution.

The InverseKinematicsSolver objective:

\[ min: J = sum(Wm_i*(m_i-md_i)^T*(m_i-md_i)) + sum(Wq_j*(q_j-qd_j)^2) + [Wc*sum(c_{err})^2] \]

where m_i and md_i are the model and desired marker locations (Vec3); q_j and qd_j are model and desired joint coordinates. Wm_i and Wq_j are the marker and coordinate weightings, respectively, and Wc is the weighting on constraint errors. When Wc == Infinity, the second term is not included, but instead q is subject to the constraint equations:

\[ c_{err} = G(q)-Go = 0 \]

When the model (and the number of goals) is guaranteed not to change and the initial state is close to the InverseKinematics solution (e.g., from the initial assemble()), then track() is an efficient method for updating the configuration to determine the small change in coordinate values, q.

See SimTK::Assembler for more algorithmic details of the underlying solver.
