RotationInterpolator

public RotationInterpolator(Alpha alpha,
                            TransformGroup target,
                            Transform3D axisOfRotation,
                            float minimumAngle,
                            float maximumAngle)


Constructs a new rotation interpolator that varies 
the target transform node's rotational component.

Parameters:
 	alpha - the alpha generator to use in the 
			rotation computation
	target - the TransformGroup node affected 
			by this interpolator
	axisOfRotation - the transform that defines the 
			local coordinate system in which this 
			interpolator operates. The rotation is done
			about the Y-axis of this local coordinate system.
	minimumAngle - the starting angle in radians
	maximumAngle - the ending angle in radians

Alpha

public Alpha(int loopCount,
             long increasingAlphaDuration)


This constructor takes only the loopCount and 
increasingAlphaDuration as parameters and assigns the
default values to all of the other parameters.

Parameters:
	loopCount - number of times to run this alpha; a value 
			of -1 specifies that the alpha loops indefinitely
	increasingAlphaDuration - period of time during which 
			alpha goes from zero to one
