QuickTime 4 Reference

Tween Components for QuickDraw 3D

QuickTime includes a number of components that perform tween operations on QuickDraw 3D objects. These components are described in the following sections. Each component processes two input values and returns one output value, all of the same type. The tween algorithm in all cases performs a visually smooth interpolation between the two objects. The tween types and the QuickDraw 3D data structures that they interpolate are the following:

Tween type	QuickDraw 3D data structure
`kTweenType3dCameraData`	`TQ3CameraData`
`kTweenType3dMatrix`	`TQ3Matrix4x4`
`kTweenType3dMatrixNonLinear`	`TQ3Matrix4x4`
`kTweenType3dQuaternion`	`TQ3Quaternion`
`kTweenType3dRotate`	`TQ3RotateTransformData`
`kTweenType3dRotateAboutAxis`	`TQ3RotateAboutAxisTransformData`
`kTweenType3dRotateAboutPoint`	`TQ3RotateAboutPointTransformData`
`kTweenType3dRotateAboutVector`	`TQ3RotateTransformData`
`kTweenType3dScale`	`TQ3Vector3D`
`kTweenType3dSoundLocalizationData`	`SSpLocalizationData`
`kTweenType3dTranslate`	`TQ3Vector3D`
