Hi Robert, I was also thinking about a special CameraManipulator for the Rift. The drawback with making a special manipulator would be that the simple solution of just applying a ViewConfig would be lost. Since you will have to apply a view config and then apply a special view manipulator. I kind of like the idea of letting the user choose what type of camera manipulator they want and still getting the Rift orientations. So with this in mind I am thinking about your second suggestion; to track the view matrix offset and correspondingly update the slave view offsets. Which was pretty much my original idea. But this gives rise to some almost philosophical questions, some of the standard manipulators would work well with Rift Orientation changes overloaded such as "DriveManipulator", "FlightManipulator". Others are more questionable such as "OrbitManipulator" and "TrackBallManipulator". And then there are manipulators which would become very weird with Rift Orientation stacked such as "FirstPersonManipulator". Although this would be up to each developer to try what works for them. So my idea was to follow you second suggestion to track the main camera view matrix. But I am not sure how to best do this. Should I connect a callback to the main camera inside the configure method in my ViewConfig class? Or are there simpler ways to do this?
