Matrix

This article introduces the concept of using Spline Basis Functions for rigging, allowing for “curves” that also include rotation or scale! ...

This article shows how to recreate the behavior of a parent constraint with matrix nodes. This method is superior as it also handles scale and shear gracefully. Note: Make sure rotateOrder is connected, as the issue mentioned in the article has since been fixed. ...

Extracting a twist value from a control is a common need, this article shows a very simple (but very robust) quaternion based method (Quaternion Swing-Twist Decomposition). Note: The Quaternion Swing-Twist Decomposition in this article is the same concept as what the Maya Pose Interpolator uses. ...
