## Geoml

Geoml is 2D geometry library for OCaml. It focuses on euclidean geometry
and provides basic types and operations over geometric shapes.

Here an example showing a way to construct geometrically a golden rectangle from four points defining a square:

``````  open Geoml

let gold_rect (a,b,c,d) =
let e = Point.center a b and ab = Line.of_points a b in
let circ = Point.distance e c |> Circle.make e in
let f =
match Circle.line_intersection circ ab with
| [x;y] -> if Point.sq_distance a x > Point.sq_distance a y then x else y
| _ -> assert false
in
let fg = Line.perpendicular_of_line ab f and dc = Line.of_points d c in
let g = Line.intersection fg dc in
Rectangle.make d (Point.distance d g) (Point.distance d a)
``````

It also implements several cool algorithms :

• Emo Welzl's smallest enclosing disk algorithm

• Graham's scan method for finding a convex hull.

• Weiler-Atherton for polygon clipping

• Ear-clipping Algorithm for Polygon triangulation (Mei, Tipper & Xu)

You can see some examples of application in the tests directory (You'll need Graphics)

###### Build
• The library : make

• The tests : make tests

###### Documentation

You can build locally the documentation by doing `make doc`, or consult
the online documentation.

###### Current

Geoml is currently still in developpement, and have not been tested
-nor proved, nor model-checked nor analyzed ... but you know what they
say about well typed program ;) -. Thereby, you might find some weird
behaviors or failures. Feel free to let us know or report an issue
about it. The modules Point, Line, Rectangle, Vector, Triangle,
Segment, Circle
are pretty much usable while the Polygon,
Polyhedron, Curve, Ellipse, Shape ...
modules are not quite ready to
be used and you should not rely on the code in it.

You are also welcome to contact any member of the developpement team
if you want to report a bug or suggest a feature you think it may be
cool to have in Geoml.
