QuickTime VR in 3-D

Just as 3-D rendering systems mimic the functionality of a camera or movie camera for creating realistic images, 3-D systems can be used to take the pictures required for QuickTime VR panoramas and object movies. The principle is simply to use the virtual camera in 3-D space exactly the same way that you use a camera in the real world to create photo VR images. For QuickTime VR panoramas, 3-D programs have the unique advantages of mathematical precision, of perfect leveling, and of limited parallax error.

Cameras in 3-D systems are exactly centered at the focal point, so the parallax problem is gone, and leveling a camera is simply a matter of making sure that it is aligned on the appropriate plane in 3-D space.
