Method Detail

findIntersection

public static Coords3d findIntersection(Coords3d e1v1,
                                        Coords3d e1v2,
                                        Coords3d e2v1,
                                        Coords3d e2v2)

Finds the intersection of the e1v1-e1v2 and e2v1-e2v2 line segments. Returns with the coordinate of the intersection or null if it doesn't exist.

Parameters:

e1v1 - the start of the first line segment

e1v2 - the end of the first line segment

e2v1 - the start of the second line segment

e2v2 - the end of the second line segment

Returns:

the coordinate of the intersection or null if the two line segments are not crossing

findCross

public static Coords2d findCross(LineSegment2d segment1,
                                 LineSegment2d segment2)

Finds the cross point between two line segments.

Parameters:

segment1 - the first line segment

segment2 - the second line segment

Returns:

the cross point or null if the two line segment is not crossing
