Disney Research presents their work on the Tangent Space Optimization of Controls for Character Animation.  the control of interpolations in animation with positional constraints over time as a space-time optimization problem in the tangent space of the curves driving the animation controls.

Tangent Space Optimization of Controls for Character Animation

The control of interpolations in animation with positional constraints over time as a space-time optimization problem in the tangent space of the curves driving the animation. Their method has the key properties that it (1) allows for the manipulation of positions and orientations over time, extending inverse kinematics, (2) does not add new keyframes, and 3) works in the space of editable animation curves and hence integrates seamlessly with current pipelines.
