Rotation interpolator behavior. This class defines a behavior
that modifies the rotational component of its target TransformGroup
by linearly interpolating between a pair of specified angles
(using the value generated by the specified Alpha object).
The interpolated angle is used to generate a rotation transform
about the local Y-axis of this interpolator.

RotationInterpolator
Constructs a trivial rotation interpolator with a specified target, an default axisOfTranform set to identity, a minimum angle of 0.0f, and a maximum angle of 2*pi radians.- Parameters:
alpha
- The alpha object for this Interpolatortarget
- The target for this rotation Interpolator
-
RotationInterpolator
public RotationInterpolator(Alpha alpha, TransformGroup target, Transform3D axisOfTransform, 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 computationtarget
- the TransformGroup node affected by this interpolatoraxisOfTransform
- 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 radiansmaximumAngle
- the ending angle in radians
-
