Media Data Atom TypesTween MediaList Tween AtomskListElementTypeSpecifies the atom type of the elements in a list tween atom.Its parent atom is a kTweenData atom.A kTweenEntry atom can contain only one kListElementType atom. The ID of this atom is always 1.The index of this atom is always 1.This atom is a leaf atom. Its data type is QTAtomType.This atom is required in the kTweenData atom for a list tween atom.3D Tween AtomskTween3dInitialConditionSpecifies an initial transform for a 3D tween atom whose tween type is one of the following:kTweenType3dCameraData, kTweenType3dMatrix, kTweenType3dQuaternion,kTweenType3dRotate, kTweenType3dRotateAboutAxis, kTweenType3dRotateAboutAxis,kTweenType3dRotateAboutPoint, kTweenType3dRotateAboutVector, kTweenType3dScale, orkTweenType3dTranslate.Its parent atom is a kTweenEntry atom.A kTweenEntry atom can contain only one kTween3dInitialCondition atom. The ID of this atomis always 1. The index of this atom is always 1.This atom is a leaf atom. The data type of its data is one of the values listed in Table 4-16 (page 243).Table 4-16Tween typesTween TypekTweenType3dCameraDatakTweenType3dMatrixkTweenType3dQuaternionkTweenType3dRotatekTweenType3dRotateAboutAxiskTweenType3dRotateAboutPointkTweenType3dRotateAboutVectorkTweenType3dScaleData TypeTQ3CameraDataTQ3Matrix4x4TQ3QuaternionTQ3RotateTransformDataTQ3RotateAboutAxisTransformDataTQ3RotateAboutPointTransformDataTQ3PlaneEquationTQ3Vector3D2012-08-14 | © 2004, 2012 Apple Inc.
