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.- See Also:

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 usesVector3D.COORDINATE_ASCENDING_ORDER
with the intersection normals.

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 withprecision
- 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 theeq(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 testlist
- list to test against- Returns:
- true if the given linecast point is equivalent to any of those in the given list
