The concrete class name for an object derived from ObjectBase.
If you want to know if an object is of a certain type you should use
objectBase.isAClassName
var t = pack.createObject('o3d.Transform');
t.className == 'o3d.Transform'; // true
This property is read-only.
Unique id of the object.
This id will be unique, even across multiple O3D clients in the same
page.
This property is read-only.
The object's name.
Setting this has no meaning to O3D, but is useful for debugging and for
the functions Client.getObjects, Pack.getObject,
RenderNode.getRenderNodesByNameInTree and
RenderNode.getTransformsByNameInTree
which search for objects by name.
