Class LinecastPoint2D


public class LinecastPoint2D extends AbstractLinecastPoint<Vector2D,Vector2D.Unit,Line>
Class representing intersections resulting from linecast operations in Euclidean 2D space. This class contains the intersection point along with the boundary normal of the target at the point of intersection.

      public LinecastPoint2D(Vector2D point, Vector2D normal, Line line)
      Construct a new instance from its components.
      Parameters:
      point - the linecast intersection point
      normal - the surface of the linecast target at the intersection point
      line - intersecting line
  • Method Details

    • eq

      public boolean eq(LinecastPoint2D other, org.apache.commons.numbers.core.Precision.DoubleEquivalence precision)
      Return true if this instance should be considered equivalent to the argument, using the given precision context for comparison. Instances are considered equivalent if they have equivalent points, normals, and lines.
      Parameters:
      other - point to compare with
      precision - precision context to use for the comparison
      Returns:
      true if this instance should be considered equivalent to the argument
    • sortAndFilter

      public static void sortAndFilter(List<LinecastPoint2D> pts)
      Sort the given list of linecast points by increasing abscissa value and filter to remove duplicate entries (as determined by the eq(LinecastPoint2D, Precision.DoubleEquivalence) method). The argument is modified.
      Parameters:
      pts - list of points to sort and filter
    • containsEq

      private static boolean containsEq(LinecastPoint2D pt, List<? extends LinecastPoint2D> list)
      Return true if the given linecast point is equivalent to any of those in the given list.
      Parameters:
      pt - point to test
      list - list to test against
      Returns:
      true if the given linecast point is equivalent to any of those in the given list
