About the QuickTime VR Manager

The QuickTime VR Manager is the part of QuickTime 3 that provides an application programming interface for controlling QuickTime VR objects and panoramas. You can use the QuickTime VR Manager to

• display panoramas and objects
• perform basic orientation, positioning, and animation control
• intercept and override QuickTime VR's mouse tracking
• modify the display quality
• intercept and override QuickTime VR's default hot spot behavior
• composite flat or perspective overlays (such as QuickDraw 3D objects or QuickTime movies)
• specify transition effects
• get the viewing limits of a node and get and set a node's viewing constraints
• control QuickTime VR's memory usage
• intercept calls to some QuickTime VR Manager functions and modify their behavior

This section describes the main concepts with which you need to be familiar to use the QuickTime VR Manager. See "Using the QuickTime VR Manager" for code examples showing how to use the QuickTime VR Manager.

You do not need to use the QuickTime VR Manager simply to open and display a QuickTime VR movie. The QuickTime VR movie controller automatically provides the basic mouse-and-keyboard-driven interface and handles all necessary memory allocation. You need to use the QuickTime VR Manager only if you want to exercise programmatic control over object or panoramic nodes.
