Method Details

intersectRayRayEx

public static IntersectionResultEx intersectRayRayEx(Point2D ao,
 Point2D ad,
 Point2D bo,
 Point2D bd)

Computes the intersection between two infinitely long rays 'a' and 'b'.

The intersection will contain the parameters 't' of ray 'a' in range [0,MAX_VALUE].

The computed intersection will have one of the states IntersectionStatus.INTERSECTION, IntersectionStatus.NO_INTERSECTION_COINCIDENT, IntersectionStatus.NO_INTERSECTION_PARALLEL,

Parameters:

ao - origin of ray 'a'

ad - direction of ray 'a'

bo - origin of ray 'b'

bd - directoin of ray 'b'

Returns:

computed intersection

intersectRayRayEx

public static IntersectionResultEx intersectRayRayEx(double aox,
 double aoy,
 double adx,
 double ady,
 double box,
 double boy,
 double bdx,
 double bdy)

Computes the intersection between two infinitely long rays 'a' and 'b'.

The intersection will contain the parameters 't' of ray 'a' and ray 'b' in range [0,MAX_VALUE].

Parameters:

aox - x origin of ray 'a'

aoy - y origin of ray 'a'

adx - x direction of ray 'a'

ady - y direction of ray 'a'

box - x origin of ray 'b'

boy - y origin of ray 'b'

bdx - x direction of ray 'b'

bdy - y direction of ray 'b'

Returns:

computed intersection

intersectRayRayEx

public static IntersectionResultEx intersectRayRayEx(double aox,
 double aoy,
 double adx,
 double ady,
 double amax,
 double box,
 double boy,
 double bdx,
 double bdy,
 double bmax,
 double epsilon)

Computes the intersection between two infinitely long rays 'a' and 'b'.

The intersection will contain the parameters 't' of ray 'a' in range [0,maxT].

This method can produce the following IntersectionStatus codes:

IntersectionStatus.INTERSECTION

The line segments intersect at the IntersectionPointEx given in the result.

IntersectionStatus.NO_INTERSECTION

The line segments do not intersect, but lines of infinite length, will intersect at the IntersectionPointEx given in the result.

IntersectionStatus.NO_INTERSECTION_COINCIDENT

The lines segments do not intersect because they are coincident. Coincidence starts and ends at the two IntersectionPointExs given in the result.

IntersectionStatus.NO_INTERSECTION_PARALLEL

The lines segments do not intersect because they are parallel.

Parameters:

aox - x origin of ray 'a'

aoy - y origin of ray 'a'

adx - x direction of ray 'a'

ady - y direction of ray 'a'

amax - maximal parameter value of ray 'a'

box - x origin of ray 'b'

boy - y origin of ray 'b'

bdx - x direction of ray 'b'

bdy - y direction of ray 'b'

bmax - maximal parameter value of ray 'b'

Returns:

computed intersection
