Setting Observer View
At this point, the tracking sources should all be working, and moving the physical camera will move the camera in the virtual scene. To get a clearer idea of what the virtual camera is doing, click the Observer View button in the upper right hand corner of the user interface.
The Observer camera defaults to the same view as the main scene camera, so at first there is not much difference. Roll the mouse scroll wheel backwards, and a yellow virtual camera will appear in front.
Navigation with the Observer View camera is very similar to Maya:
Holding down Alt while clicking and dragging with the left mouse button will cause the scene to orbit around geometry that is near the center of the screen.
Holding down Alt while clicking and dragging with the middle mouse button will cause the scene to slide laterally back and forth.
Scrolling in and out with the mouse scroll wheel causes the virtual camera to translate back and forth on its view axis. Zoom is fixed at a 50 degree field of view.
Holding down Alt and Shift while clicking and dragging with the left mouse button will cause the observer view to rotate in place around the existing observer view position.
Reset Observer View
To reset the Observer View camera position to the current scene camera view, click Reset in the upper right hand corner under the Observer View Enable button.
Disable Observer View
To disable Observer View, and return to the scene camera view, deselect the Enable button in the Observer View layout.
