Bone (Nu)

Bone Type

Namespace: Spine
Assembly: Nu.Spine.dll
Base Type: obj
All Interfaces: IUpdatable

Stores a bone's current pose.

A bone has a local transform which is used to compute its world transform. A bone also has an applied transform, which is a local transform that can be applied to compute the world transform. The local transform and applied transform may differ if a constraint or application code modifies the world transform after it was computed from the local transform.

`this.UpdateAppliedTransform` Full Usage: `this.UpdateAppliedTransform`	Computes the applied transform values from the world transform. If the world transform is modified (by a constraint, Bone.RotateWorld, etc) then this method should be called so the applied transform matches the world transform. The applied transform may be needed by other code (eg to apply another constraint). Some information is ambiguous in the world transform, such as -1,-1 scale versus 180 rotation. The applied transform after calling this method is equivalent to the local transform used to compute the world transform, but may not be identical.
