Description
Segments in two dimensions are special since we may meaningfully compute their point of intersection with a ray.

Segment intersections
intersectPointsS :: OrderedField n => FixedSegment V2 n -> FixedSegment V2 n -> [P2 n] #
Compute the intersections between two fixed segments.
intersectPointsS' :: OrderedField n => n -> FixedSegment V2 n -> FixedSegment V2 n -> [P2 n] #
Compute the intersections between two segments using the given tolerance.
Closest point on a segment
closestPoint :: OrderedField n => FixedSegment V2 n -> P2 n -> [P2 n] #
Get the closest point(s) on a FixedSegment from a point.
closestPoint' :: OrderedField n => n -> FixedSegment V2 n -> P2 n -> [P2 n] #
Get the closest point(s) on a FixedSegment from a point within given
tolerance.
closestDistance :: OrderedField n => FixedSegment V2 n -> P2 n -> [n] #
Get the closest distance(s) from a point to a FixedSegment.
closestDistance' :: OrderedField n => n -> FixedSegment V2 n -> P2 n -> [n] #
Get the closest distance(s) from a point to a FixedSegment within given
tolerance.
closestParam :: OrderedField n => FixedSegment V2 n -> P2 n -> [n] #
Find the closest value(s) on the Bêzier to the given point.
closestParam' :: OrderedField n => n -> FixedSegment V2 n -> P2 n -> [n] #
Find the closest value(s) on the Bêzier to the given point within given tolerance.
Low level functions
segmentSegment :: OrderedField n => n -> FixedSegment V2 n -> FixedSegment V2 n -> [(n, n, P2 n)] #
Return the intersection points with the parameters at which each segment intersects.
lineSegment :: OrderedField n => n -> Located (V2 n) -> FixedSegment V2 n -> [(n, n, P2 n)] #
Return the intersection points with the parameters at which the line and segment intersect.
