Object Controller Types
The
movieType
field of the object sample atom structure
(Object Sample Atom Structure)
specifies an object controller type, that is, the user interface to be used to manipulate the object. QuickTime VR supports the following controller types:
enum ObjectUITypes {
kGrabberScrollerUI = 1,
kOldJoyStickUI = 2,
kJoystickUI = 3,
kGrabberUI = 4,
kAbsoluteUI = 5
};
