Class CatmullRomSpline

java.lang.Object
com.ardor3d.spline.CatmullRomSpline
All Implemented Interfaces:
Spline
public class CatmullRomSpline extends Object implements Spline
CatmullRomSpline class is an implementation of spline that uses the Catmull-Rom equation: 
 q(t) = 0.5 * ((2 * P1) + (-P0 + P2) * t + (2 * P0 - 5 * P1 + 4 * P2 - P3) * t2 + (-P0 + 3 * P1 - 3 * P2 + P3) * t3)

      public Vector3 interpolate(ReadOnlyVector3 p0, ReadOnlyVector3 p1, ReadOnlyVector3 p2, ReadOnlyVector3 p3, double t)
      Description copied from interface: Spline
      Will return an interpolated vector between parameters p1 and p2 using t.
      Specified by:
      interpolate in interface Spline
      Parameters:
      p0 - The starting control point.
      p1 - The second control point.
      p2 - The third control point.
      p3 - The final control point.
      t - Should be between zero and one. Zero will return point p1 while one will return p2, a value in between will return an interpolated vector between the two.
      Returns:
      The interpolated vector.

      public Vector3 interpolate(ReadOnlyVector3 p0, ReadOnlyVector3 p1, ReadOnlyVector3 p2, ReadOnlyVector3 p3, double t, Vector3 result)
      If any vector is null then the result is just returned unchanged.
      Specified by:
      interpolate in interface Spline
      Parameters:
      p0 - The start control point.
      p1 - Result will be between this and p2.
      p2 - result will be between this and p1.
      p3 - The end control point.
      t - 0.0 <= t <= 1.0, if t <= 0.0 then result will be contain exact same values as p1 and if its >= 1.0 it will contain the exact same values as p2.
      result - The results from the interpolation will be stored in this vector.
      Returns:
      The result vector as a convenience.
