public class IntersectionRecord extends Object

  • Constructor Details

    • IntersectionRecord

      public IntersectionRecord(double[] distances, Vector3[] points)
      Instantiates a new IntersectionRecord defining the distances and points.
      Parameters:
      distances - the distances of this intersection.
      points - the points of this intersection.
      Throws:
      Ardor3dException - if distances.length != points.length

    • IntersectionRecord

      public IntersectionRecord(double[] distances, Vector3[] points, List<PrimitiveKey> primitives)
