For the case in which the screen is not attached to the user's head, the renderer already has enough information to generate a frame. When there is one display and no tracking is being used, the problem is relatively trivial. We only need to assume a fixed distance from the eyes to the display. Regardless of the true position of the head, Java 3D is rendering a frame appropriate for an assumed head, sitting in front of the screen.

In this most simple case, we can set several of the transforms to unity. Setting the transform to unity has the effect of canceling ...
