data LineSegment d p r Source #

Line segments. LineSegments have a start and end point, both of which may contain additional data of type p. We can think of a Line-Segment being defined as

>>> data LineSegment d p r = LineSegment (EndPoint (Point d r :+ p)) (EndPoint (Point d r :+ p))

Test if a value lies in an interval. Note that the difference between inInterval and inRange is that the extra value is *not* used in the comparison with inInterval, whereas it is in inRange.

Directly convert a line into a line segment.

onSegment :: (Ord r, Fractional r, Arity d) => Point d r -> LineSegment d p r -> Bool Source #

Test if a point lies on a line segment.

>>> (point2 1 0) onSegment (ClosedLineSegment (origin :+ ()) (point2 2 0 :+ ()))
True
>>> (point2 1 1) onSegment (ClosedLineSegment (origin :+ ()) (point2 2 0 :+ ()))
False
>>> (point2 5 0) onSegment (ClosedLineSegment (origin :+ ()) (point2 2 0 :+ ()))
False
>>> (point2 (-1) 0) onSegment (ClosedLineSegment (origin :+ ()) (point2 2 0 :+ ()))
False
>>> (point2 1 1) onSegment (ClosedLineSegment (origin :+ ()) (point2 3 3 :+ ()))
True


Note that the segments are assumed to be closed. So the end points lie on the segment.

>>> (point2 2 0) onSegment (ClosedLineSegment (origin :+ ()) (point2 2 0 :+ ()))
True
>>> origin onSegment (ClosedLineSegment (origin :+ ()) (point2 2 0 :+ ()))
True


This function works for arbitrary dimensons.

>>> (point3 1 1 1) onSegment (ClosedLineSegment (origin :+ ()) (point3 3 3 3 :+ ()))
True
>>> (point3 1 2 1) onSegment (ClosedLineSegment (origin :+ ()) (point3 3 3 3 :+ ()))
False


orderedEndPoints :: Ord r => LineSegment 2 p r -> (Point 2 r :+ p, Point 2 r :+ p) Source #

The left and right end point (or left below right if they have equal x-coords)

segmentLength :: (Arity d, Floating r) => LineSegment d p r -> r Source #

Length of the line segment

sqDistanceToSeg :: (Arity d, Fractional r, Ord r) => Point d r -> LineSegment d p r -> r Source #

Squared distance from the point to the Segment s. The same remark as for the sqDistanceToSegArg applies here.

sqDistanceToSegArg :: (Arity d, Fractional r, Ord r) => Point d r -> LineSegment d p r -> (r, Point d r) Source #

Squared distance from the point to the Segment s, and the point on s realizing it. Note that if the segment is *open*, the closest point returned may be one of the (open) end points, even though technically the end point does not lie on the segment. (The true closest point then lies arbitrarily close to the end point).

flipSegment :: LineSegment d p r -> LineSegment d p r Source #

flips the start and end point of the segment
