[name]
Base class for scene graph objects.
Constructor
[name]()
The constructor takes no arguments.
Properties
[property:Integer id]
readonly – Unique number for this object instance.
[property:String uuid]
[link:http://en.wikipedia.org/wiki/Universally_unique_identifier UUID] of this object instance.
This gets automatically assigned, so this shouldn't be edited.
[property:String name]
Optional name of the object (doesn't need to be unique).
[property:Object3D parent]
Object's parent in the scene graph.
[property:Object3D children]
Array with object's children.
[property:Vector3 position]
Object's local position.
[property:Euler rotation]
[property:Vector3 scale]
Object's local scale.
[property:Vector3 up]
Up direction. Default is THREE.Vector3( 0, 1, 0 ).
[property:Matrix4 matrix]
Local transform.
[property:Quaternion quaternion]
Object's local rotation as [page:Quaternion Quaternion].
[property:Boolean visible]
Object gets rendered if *true*.
default – true
[property:Boolean castShadow]
Gets rendered into shadow map.
default – false
[property:Boolean receiveShadow]
Material gets baked in shadow receiving.
default – false
[property:Boolean frustumCulled]
When this is set, it checks every frame if the object is in the frustum of the camera. Otherwise the object gets drawn every frame even if it isn't visible.
default – true
[property:Boolean matrixAutoUpdate]
When this is set, it calculates the matrix of position, (rotation or quaternion) and scale every frame and also recalculates the matrixWorld property.
default – true
[property:Boolean matrixWorldNeedsUpdate]
When this is set, it calculates the matrixWorld in that frame and resets this property to false.
default – false
[property:object userData]
An object that can be used to store custom data about the Object3d. It should not hold references to functions as these will not be cloned.
[property:Matrix4 matrixWorld]
The global transform of the object. If the Object3d has no parent, then it's identical to the local transform.

recursive -- if true, descendants of the object are also cloned. Default is true.
Returns a clone of this object and optionaly all descendants.
[method:Object3D getObjectByName]( [page:String name] )
name -- String to match to the children's Object3d.name property.
Searches through the object's children and returns the first with a matching name.
[method:Object3D getObjectById]( [page:Integer id] )
id -- Unique number of the object instance
