Class Blend_d_f

  • Direct Known Subclasses:
    LloydHaywardBlend_d_f, ParabolicBlend_d_f
    public class Blend_d_f
extends java.lang.Object
    Interface for blending

    A Blend describes a way to blend between to consecutive interpolators. If we let
    t_1 be the time switching from one interpolator to the next, then the blend
    control the path in the interval [t_1-\tau_1;t_1+\tau_2].

    See the specific implementations for at description of which template
    arguments that are valid.
