Subject: [Imstk-users] Attaching objects to the camera controller
Message-ID: <C745C1E748CE104AA373B656E0EF5E309A8F42DA@ex14mb4.win.rpi.edu>

Is there a way to attach objects to the camera controller? I would like to be able to attach a light to it, and I'm not sure if this is already something that's been done.

There is an option in VTK to instantiate a light as a headlight, but I
don't know if we have the interface for that in iMSTK.

You can attach objects, cameras by connecting their controller to the same
device, I believe Sreekanth did some work on this to optimize it so that
the controllers wouldn't need to recompute the values if they share the
same device client, but you might want to check with him. As far as lights
go, we don't have a controller class for them yet, but that would be easy
to implement and have it work the same way than the others.

I agree, it should be similar to camera controller. I set a flag to track
which device is already updated in a given frame so that each client is
updated once per frame.
