Array with object's animation clips.

OptionalcustomSame as customDepthMaterial, but used with THREE.Object3DPointLight | PointLight.
When this is set, it checks every frame if the object is in the frustum of the camera before rendering the object.
If set to false the object gets rendered every frame even if it is not in the frustum of the camera.
ReadonlyidUnique number for this Object3D instance.
ReadonlyisFlag to check if a given object is of type Object3D.
Readonlyis是否为瓦片
The layer membership of the object.
The local transform matrix.
When this is set, it calculates the matrix of position, (rotation or quaternion) and scale every frame and also recalculates the matrixWorld property.
DEFAULT_MATRIX_AUTO_UPDATE - that is (true).
The global transform of the object.
If set, then the renderer checks every frame if the object and its children need matrix updates. When it isn't, then you have to maintain all matrices in the object and its children yourself.
DEFAULT_MATRIX_WORLD_AUTO_UPDATE - that is (true).
When this is set, it calculates the matrixWorld in that frame and resets this property to false.
ReadonlymodelOptional name of the object
ReadonlynormalOptionalocclusionObject's parent in the scene graph.
The pivot point for rotation and scale transformations. When set, rotation and scale are applied around this point instead of the object's origin.
ReadonlypositionObject's local position.
ReadonlyquaternionObject's local rotation as a THREE.Quaternion | Quaternion.
Whether the material receives shadows.
This value allows the default rendering order of scene graph objects to be overridden although opaque and transparent objects remain sorted independently.
ReadonlyrotationObject's local rotation (Euler angles), in radians.
ReadonlyscaleThe object's local scale.
Whether the 3D object is supposed to be static or not. If set to true, it means
the 3D object is not going to be changed after the initial renderer. This includes
geometry and material settings. A static 3D object can be processed by the renderer
slightly faster since certain state checks can be bypassed.
Only relevant in context of WebGPURenderer.
ReadonlytypeA Read-only string to check this object type.
This is used by the lookAt method, for example, to determine the orientation of the result.
Object3D.DEFAULT_UP - that is (0, 1, 0).
An object that can be used to store custom data about the Object3D.
UUID of this object instance.
Object gets rendered if true.

StaticDEFAULT_The default setting for matrixAutoUpdate for newly created Object3Ds.
StaticDEFAULT_The default setting for matrixWorldAutoUpdate for newly created Object3Ds.
StaticDEFAULT_The default up direction for objects, also used as the default position for THREE.DirectionalLight | DirectionalLight, THREE.HemisphereLight | HemisphereLight and THREE.Spotlight | Spotlight (which creates lights shining from the top down).

An optional callback that is executed immediately after a 3D object is rendered.
This function is called with the following parameters: renderer, scene, camera, geometry, material, group.
Please notice that this callback is only executed for renderable 3D objects. Meaning 3D objects which
define their visual appearance with geometries and materials like instances of Mesh, Line,
Points or Sprite. Instances of Object3D, Group or Bone are not renderable
and thus this callback is not executed for such objects.
An optional callback that is executed immediately after a 3D object is rendered to a shadow map.
This function is called with the following parameters: renderer, scene, camera, shadowCamera, geometry,
depthMaterial, group.
