Comments
The camera settings associated with the currently active window will change to display a flat perspective. To restore the camera to its default wide angle view, click the perspective button, or manually set the distance and zoom angle using the camera input boxes.
GIG does not use a true parallel projection (flat perspective). Instead, the effect is approximated by moving the camera very far back (25000 units) and making the camera angle very small (0.1146 degrees).
It is not recommended to render an image in no perspective. Because of the extreme distance of the camera to the object, the rendered image may not show the result one expects.
