Package me.wobblyyyy.pathfinder.trajectory

Class SplineInterpolator

java.lang.Object
me.wobblyyyy.pathfinder.trajectory.SplineInterpolator
public class SplineInterpolator
extends java.lang.Object
Interpolate splines by using the Fritsch-Carlson computational method for determining control points for a spline. This class isn't really all that useful on its own - rather, you should go check out the much more usable Spline class - that'll get what you need done.

    • invertedMonotoneCubic

      public static SplineInterpolator invertedMonotoneCubic​(java.util.List<java.lang.Double> xList, java.util.List<java.lang.Double> yList)
      Create a new inverted monotone cubic spline.
      Parameters:
      xList - the X components of the spline.
      yList - the Y components of the spline.
      Returns:
      a newly-created inverted spline that passes through each of the provided points.

    • monotoneCubic

      public static SplineInterpolator monotoneCubic​(java.util.List<java.lang.Double> x, java.util.List<java.lang.Double> y)
      Create a new monotone cubic spline.
      Parameters:
      x - the X components of the spline.
      y - the Y components of the spline.
      Returns:
      a newly-created spline that passes through each of the provided X/Y control points - very cool, I know.
