public class RotPosPathInterpolator
extends Interpolator
Rotation and Position path interpolation behavior. This class constructs a behavior that varies the rotation and position component of its target TransformGroup by interpolating among a series of predefined orientations and positions.

Constructor Index

o RotPosPathInterpolator(Alpha, TransformGroup, Transform3D, float[], Quat4f[], Point3f[])
