DESCRIPTION

The QTVRSetTransitionProperty function sets the value of the transition property whose type is specified by the transitionType and transitionProperty parameters for the movie specified by the qtvr parameter to the value specified by the transitionValue parameter.

Note that calling QTVRSetTransitionProperty simply sets a transition property's value; you must still call QTVREnableTransition to enable that transition effect.

SPECIAL CONSIDERATIONS

QTVRSetTransitionProperty is valid only for panoramic nodes.
