A Track of quaternion keyframe values.
[page:String name] (required) identifier for the KeyframeTrack.
[page:Array times] (required) array of keyframe times.
[page:Array values] values for the keyframes at the times specified.
[page:Constant interpolation] the type of interpolation to use. See
[page:Animation Animation Constants] for possible values. Default is
[page:Animation InterpolateLinear].
See [page:KeyframeTrack] for inherited properties.
The default interpolation type to use, [page:Animation InterpolateLinear].
String 'quaternion'.
See [page:KeyframeTrack] for inherited methods.
Returns a new [page:QuaternionLinearInterpolant QuaternionLinearInterpolant] based on the [page:KeyframeTrack.values values], [page:KeyframeTrack.times times] and [page:KeyframeTrack.valueSize valueSize] of the keyframes.
