Animation Settings

The animationSettings field of the object sample atom (link) is a long integer that specifies a set of animation settings for an object node. Animation settings specify characteristics of the movie while it is playing. You can use these constants to specify animation settings:

enum QTVRAnimationSettings {
    kQTVRObjectAnimateViewFramesOn              = (1 << 0),
    kQTVRObjectPalindromeViewFramesOn           = (1 << 1),
    kQTVRObjectStartFirstViewFrameOn            = (1 << 2),
    kQTVRObjectAnimateViewsOn                   = (1 << 3),
    kQTVRObjectPalindromeViewsOn                = (1 << 4),
    kQTVRObjectSyncViewToFrameRate              = (1 << 5),
    kQTVRObjectDontLoopViewFramesOn             = (1 << 6),
    kQTVRObjectPlayEveryViewFrameOn             = (1 << 7)
};

Constant descriptions

kQTVRObjectAnimateViewFramesOn
If this bit is set, play all frames in the current view state.
kQTVRObjectPalindromeViewFramesOn
If this bit is set, play a back-and-forth animation of the frames of the current view state.
kQTVRObjectStartFirstViewFrameOn
If this bit is set, play the frame animation starting with the first frame in the view (that is, at the view start time).
kQTVRObjectAnimateViewsOn
If this bit is set, play all views of the current object in the default row of views.
kQTVRObjectPalindromeViewsOn
If this bit is set, play a back-and-forth animation of all views of the current object in the default row of views.
kQTVRObjectSyncViewToFrameRate
If this bit is set, synchronize the view animation to the frame animation and use the same options as for frame animation.
kQTVRObjectDontLoopViewFramesOn
If this bit is set, stop playing the frame animation in the current view at the end.
kQTVRObjectPlayEveryViewFrameOn
If this bit is set, play every view frame regardless of play rate. The play rate is used to adjust the duration in which a frame appears but no frames are skipped so the rate is not exact.
