What's New in QuickTime 5
| Previous | Chapter Contents | Chapter Top | Next |
The QuickTime 5 release incorporates a new QuickTime VR cubic playback engine, which is discussed in this section.
A new type of QuickTime VR panorama is introduced in QuickTime 5 -- the cubic panorama. This new type is represented by six faces of a cube, thus enabling the viewer to see all the way up and all the way down.
Note that QuickTime VR cubic playback is backward compatible, i.e., cubic VRs will play in earlier versions of QuickTime as panoramas, with some distortion.
The following API calls (in QuickTimeVR.h ), when used with cubes, are not supported in the QuickTime 5 release: QTVRSetBackBufferImagingProc and QTVRRefreshBackBuffer . If you use either of these calls, they will return an error for cubes.
