You can use the QTVRGetAngularUnits function to get the type of unit currently used when specifying angles.

QTVRAngularUnits QTVRGetAngularUnits (QTVRInstance qtvr);
qtvr
An instance of a QuickTime VR movie.
function result
A constant that indicates the type of angular units currently in use. See "Angular Unit Types" for a description of the available angular unit types.

DESCRIPTION

The QTVRGetAngularUnits function returns, as its function result, a constant that indicates the type of angular unit currently used by the movie instance specified by the qtvr parameter. Angular values you pass to other QuickTime VR functions (for example, QTVRSetPanAngle ) are interpreted in those units.
