jointFfd

Go to: Related nodes. Attributes.

This node is used by jointLattice flexors. It deforms the components of an input object or objects using a slightly modified version of the standard FFD algorithm. Rather than using a single lattice, this node makes use of a second base lattice. This is mainly used for wrapping an ffd around a joint. The normal base is used for the points associated with the upper bone of the joint while the second base is used for the points associated with the lower bone of the joint.
