Reflector/Refractor: Expose virtual camera as a property.

[LR17]

Description

It may be useful to control some properties of the camera used by Reflector, for example to set its layers. This pull request expose the camera used by Reflector as a property of the object.

Do you mind making the same change for Refractor? It would be good to keep both classes in sync.

It may be useful to control some properties of the camera used by Reflector, for example to set its layers.

Do you mean copying the main camera layers? Or custom layers?

[LR17]

My specific use case is this: I have some sets of meshes and for each set I assign it a layer so that all the meshes of a set have the same layer. Then I want the main camera of my application to be able to see a set of layers different from the ones seen by the Reflector camera. My client code would then look like this:

const reflector = new Reflector(geometry, options); 
reflector.camera.layers.enable(3); 
reflector.camera.layers.enable(7);

[Mugen87]

Um, if the virtual camera should work with different layers than the main camera, it's indeed required to expose it.

Too bad, I was hoping we could hide the camera inside the classes. In some sense, the virtual camera is a technical detail that should not be relevant to users.

Thanks!
