Overview OVERVIEW: Skeletons are the underlying structure that will allow a character to move. Just like our own bodies, movement of our joints allows us to position ourselves and move around.

When skeletons are bound to geometry and transformed, the overlying skin is also transformed. Todays Demonstration will show the hierarchical relationship between joint and bone, parent (root) and child.
