onHalfLine :: (Ord r, Fractional r, Arity d) => Point d r -> HalfLine d r -> Bool Source #
Test if a point lies on a half-line
toHalfLine :: (Num r, Arity d) => LineSegment d p r -> HalfLine d r Source #
Transform a LineSegment into a half-line, by forgetting the second endpoint. Note that this also forgets about if the starting point was open or closed.
