A group of objects that receives a shared animation state.
For an overview of the different elements of the three.js animation system see the
"Animation System" article in the "Next Steps" section of the manual.
Add objects you would otherwise pass as 'root' to the constructor or the [page:AnimationMixer.clipAction clipAction]
method of [page:AnimationMixer AnimationMixer] and instead pass this object as 'root'.
Note that objects of this class appear as one object to the mixer,
so cache control of the individual objects must be done on the group.
The animated properties must be compatible among all objects in the group.
A single property can either be controlled through a target group or directly, but not both.
[page:Object obj] - an arbitrary number of meshes that share the same animation state.
Read-only flag to check if a given object is of type [name].
An object that contains some informations of this `AnimationObjectGroup` (total number, number in use, number of bindings per object)
The [link:http://en.wikipedia.org/wiki/Universally_unique_identifier UUID] of this `AnimationObjectGroup`. It gets automatically assigned and shouldn't be edited.
Adds an arbitrary number of objects to this `AnimationObjectGroup`.
Removes an arbitrary number of objects from this `AnimationObjectGroup`.
Deallocates all memory resources for the passed objects of this `AnimationObjectGroup`.
