Binding Tools

When a skeleton and one of its target objects are selected the control bar shows the following skeleton map specific tools:

Bind

In edit mode, this tool binds the currently selected target points to their nearest currently selected joints. In Object mode all points in the selected target objects are bound to their nearest bones of the selected skeleton.

To use the tool, multi select one or more target objects and a skeleton object. Then switch to point edit mode and select the desired bones and the target points. Click the tool and the selected points are bound to the nearest selected joints.

[Note] Note
In case more than one joint is selected, each point gets mapped only to the nearest one! To bind a point to the nearest bone, just select the point and all the joints in the skeleton.

Unbind

This tool unbinds the selected points from the selected joints. If the target object is hierarchical, its sub objects are not bound.

To use the tool, multi select a target object and a skeleton object. Then switch to edit mode and select some joints and target points. Click the tool and the selected points are unbound from the selected joints.

Let's assume some of the points representing a nose got bound to a wrong skeleton. To unbind the points from the skeleton:

To unbind a point that got bound to a wrong joint:

Points associated with the selected joint become unbound.

Select

The tool selects all target points bound to the currently selected joints.

The tool is only shown when both the target object and the skeleton object is selected.

The tool is useful, for example, when you want to view the points bound to a certain bone. Or, when some of the points got bound to a wrong bone and you want to unbind them. Just select the bone and click the 'Select' tool to select the target points as well.

Deselect

Deselect all the target points bound to the currently selected joints.

The tool is only shown when two objects are multi selected: a skeleton object and its target object. The tool is useful when binding points manually to complex hierarchical skeletons. It allows the user to exclude points already mapped to other skeletons.

Fidelity

This tool can be used for setting point wise fidelity.

To use the tool, select the desired target points and the associated joint. Then specify desired fidelity value through the fidelity field.

Fidelity is a special form of multi binding, based on the fact that in most cases multi binding operates over subsequent joints so that points near a joint behave like an elastic skin.

If the fidelity for a point is 0, then the point is bound only to one joint. If the fidelity is 0.5, then the point is bound to its closest joint with a weight 0.5 and to the next joint with a weight 0.5. In other words, such a point is influenced by two joints.

If the fidelity is 1, then only the next joint controls the point.

Weight

Sets a multi binding weight for the selected points. Select the target points and the associated joints. Then specify a weight value through the weight field.
