[name]
A [page:Layers] object assigns an [page:Object3D] to 1 or more of 32 layers numbered 0 to 31
- internally the layers are stored as a [link:https://en.wikipedia.org/wiki/Mask_(computing) bit mask], and by default all
Object3Ds are a member of layer 0.
This can be used to control visibility - an object must share a layer with a [page:Camera camera] to be visible when that camera's
view is renderered.
All classes that inherit from [page:Object3D] have an [page:Object3D.layers] property which is an instance of this class.
Constructor
[name]()
Create a new Layers object, with membership initially set to layer 0.
Properties
[property:Integer mask]
A bit mask storing which of the 32 layers this layers object is currently a member of.
Methods
[method:null disable]( [param:Integer layer] )
layer - an integer from 0 to 31.

[method:null set]( [param:Integer layer] )
layer - an integer from 0 to 31.
Set membership to *layer*, and remove membership all other layers.
[method:Boolean test]( [param:Integer layers] )
layers - a Layers object
Returns true if this and the passed *layers* object are members of the same set of layers.
