public class CatmullRomSpline extends ParametricCurve
The CatmullRomSpline is equal to the CardinalSpline with the value of alpha fixed at 0.5. The implementation for the CatmullRomSpline is about 10% faster then the CardinalSpline implementation.

    • eval

      protected void eval(double[] p)
      Description copied from class: ParametricCurve
      The eval method evaluates a point on a curve given a parametric value "t". The parametric value "t" is stored in the last index location of the specified double array. This value should not be changed. The dimension of the point to evaluate is p.length - 1. The result of the evaluation is placed in index locations 0 .. p.length - 2 (inclusive). The eval method should remain protected except for those curves that do no need any preparation to be done in the appendTo method.
      Specified by:
      eval in class ParametricCurve

    • getSampleLimit

      public int getSampleLimit()
      Returns a value of 1.
      Specified by:
      getSampleLimit in class ParametricCurve

    • appendTo

      public void appendTo(MultiPath mp)
      The requirements for this curve are the group-iterator must be in-range and have a group size of at least 4. If these requirements are not met then this method returns quietly.
