Method Detail

isPointOnLine

public static <D extends TwoMin> boolean isPointOnLine(Line<D> l,
                                                       Vec<D> p)

Checks if a point lies on a line.

Parameters:

l - the line

p - the point

Returns:

true if the point lies on the line, false if not

Throws:

java.lang.NullPointerException - if l or p is null

areLinesParallel

public static <D extends TwoMin> boolean areLinesParallel(Line<D> l1,
                                                          Line<D> l2)

Checks if two lines are parallel.

Parameters:

l1 - the first line

l2 - the second line

Returns:

true if the lines are parallel, false if not

Throws:

java.lang.NullPointerException - if l1 or l2 is null

calculateIntersectionPoint

public static <D extends TwoMin & ThreeMax> java.util.Optional<Vec<D>> calculateIntersectionPoint(Line<D> l1,
                                                                                                  Line<D> l2)

Calculates the intersection point of two lines.

Parameters:

l1 - the first line

l2 - the second line

Returns:

the intersection point of the two lines it there is one. If both lines don't intersect in a point, an empty Optional will be returned.

Throws:

java.lang.NullPointerException - if l1 or l2 is null
