Describes the possible cases of the closest parameters between finite 3D lines.

Describes the possible cases of the closest points between finite 3D lines.

The result of a line-cone intersection test. This is the return type of the function Intersection.lineCone.

Describes the possible cases of two finite 3D lines touching at their ends. Does not check if they are parallel or intersecting.

Describes the possible relationships of two finite 3D lines. Returns parameters on both lines if they intersect or are skew.

Describes the possible relationships of two finite 3D lines. Returns the intersection or closest point if they intersect or are skew.

Describes the possible relationships of two rays (rays are 3D lines extended infinitely in both directions). Returns the intersection or closest point if they intersect or are skew.

Describes the possible relationships of two rays (rays are 3D lines extended infinitely in both directions). Returns parameters on both lines if they intersect or are skew.
