Class RotationInterpolator

  • public class RotationInterpolator
extends TransformInterpolator
    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

        public RotationInterpolator​(Alpha alpha,
                            TransformGroup target)
        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 Interpolator
        target - 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 computation
        target - the TransformGroup node affected by this interpolator
        axisOfTransform - 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
