Class LinecastPoint3D


  • public class LinecastPoint3D
    extends AbstractLinecastPoint<Vector3D,​Vector3D.Unit,​Line3D>
    Class representing intersections resulting from linecast operations in Euclidean 3D space. This class contains the intersection point along with the boundary normal of the target at the point of intersection.

    • Field Detail

      • ABSCISSA_ORDER

        public static final java.util.Comparator<LinecastPoint3D> ABSCISSA_ORDER
        Comparator that sorts intersection instances by increasing abscissa order. If two abscissa values are equal, the comparison uses Vector3D.COORDINATE_ASCENDING_ORDER with the intersection normals.

      • LinecastPoint3D

        public LinecastPoint3D​(Vector3D point,
                               Vector3D normal,
                               Line3D line)
        Construct a new instance from its components.
        Parameters:
        point - intersection point
        normal - normal of the target boundary at the intersection point
        line - intersecting line
    • Method Detail

      • eq

        public boolean eq​(LinecastPoint3D 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 - other point to compare with
        precision - context to use for the comparison
        Returns:
        true if this instance should be considered equivalent to the argument
      • sortAndFilter

        public static void sortAndFilter​(java.util.List<LinecastPoint3D> pts)
        Sort the given list of linecast points by increasing abscissa value and filter to remove duplicate entries (as determined by the eq(LinecastPoint3D, Precision.DoubleEquivalence) method). The argument is modified.
        Parameters:
        pts - list of points to sort and filter
      • containsEq

        private static boolean containsEq​(LinecastPoint3D pt,
                                          java.util.List<? extends LinecastPoint3D> 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
