Hmmm, that does not really make sense because there is nothing that ties a 3D interface to any particular window. There is no connection between them. A 3D interface can be drawn on the screen, it can appear on a panel in the 3D game world, or it can appear as a hovering VR menu. The same interface could appear in a framebuffer in multiple windows. Tying a 3D interface to a window would be like tying some entity to a window.
