# [name]

用来模拟骨骼 [page:Skeleton Skeleton] 的辅助对象. 该辅助对象使用 [page:LineBasicMaterial LineBasicMaterial] 材质.

## 代码示例

`const helper = new THREE.SkeletonHelper( skinnedMesh ); scene.add( helper );`

## 例子

[example:webgl_animation_skinning_blending WebGL / animation / skinning / blending]
[example:webgl_animation_skinning_morph WebGL / animation / skinning / morph]
[example:webgl_loader_bvh WebGL / loader / bvh ]

## 构造函数

### [name]( [param:Object3D object] )

object -- Usually an instance of [page:SkinnedMesh]. However, any instance of [page:Object3D] can be used if it represents a hierarchy of [page:Bone Bone]s (via [page:Object3D.children]).

## 属性

### [property:Array bones]

辅助对象使用 [page:Line Lines] 渲染的骨数组.

### [property:Boolean isSkeletonHelper]

Read-only flag to check if a given object is of type [name].

### [property:Object3D root]

构造函数传入的对象.
