## Methods

### [method:Object3D clone]( [param:Object3D object] )

Clones the given object and its descendants, ensuring that any [page:SkinnedMesh] instances are correctly associated with their bones. Bones are also cloned, and must be descendants of the object passed to this method. Other data, like geometries and materials, are reused by reference.

### [method:Object findBoneTrackData]( [param:String name], [param:Array tracks] )

### [method:Bone getBoneByName]( [param:String name], [param:Skeleton skeleton] )

### [method:Array getBones]( [param:Skeleton skeleton] )

### [method:Array getEqualsBonesNames]( [param:Skeleton skeleton], [param:Skeleton targetSkeleton] )

### [method:SkeletonHelper getHelperFromSkeleton]( [param:Skeleton skeleton] )

### [method:Bone getNearestBone]( [param:Bone bone], [param:Array names] )

### [method:Object getSkeletonOffsets]( [param:SkeletonHelper target], [param:SkeletonHelper source], [param:Object options] )

### [method:this renameBones]( [param:Skeleton skeleton], [param:Array names] )

### [method:undefined retarget]( [param:SkeletonHelper target], [param:SkeletonHelper source], [param:Object options] )
