Remarks
Increasing the ViewFieldAngle creates the appearance of zooming out even though the observer position is unchanged. Wide angles enable the observer to see a large portion of the scene when positioned inside the data area. A wide angle also presents a distorted view, similar to that of a fish-eye lens.
Decreasing the ViewFieldAngle creates the appearance of zooming in even though the observer position is unchanged.
The default ViewFieldAngle is 55 degrees.
