getOrigin

public final Vec3 getOrigin()

Returns:

origin of the line (a point on the line)

getDirection

public final Vec3 getDirection()

Returns:

direction of the line

distance

public final float distance(Vec3 pt)

Calculate the distance (oriented) between the point and this Line.

Parameters:

pt - a point

Returns:

the closest distance of the point to the Line

distanceAlongLine

public final float distanceAlongLine(Vec3 point)

Returns:

the distance between the point and the origin, projected along the line direction

closestDistance

public final boolean closestDistance(Line other,
                                     Vec3 dstPointOnThis,

http://softsurfer.com/Archive/algorithm_0106/algorithm_0106.htm

Parameters:

dstPointOnThis - storage for the closest point on this Line, optional (could be null).

dstPointOnOther - storage for the closest point on other Line, optional (could be null).

Returns:

false if line are parallel (result is not written to storage vectors)

intersection

public final void intersection(Plane p1,
                               Plane p2)

Set this Line to be the intersection of the two planes

Parameters:

p1 - first Plane

p2 - second Plane

project

public final Vec3 project(Vec3 dst,
                          Vec3 src)

Parameters:

dst - destination vector to hold the projection result

src - point to project on the line

Returns:

dst
