delaunay is a Lua module for delaunay triangulation of a convex polygon.
##Download
###Git
git clone http://github.com/Yonaba/delaunay.git
###Archive
###LuaRocks
luarocks install delaunay
###MoonRocks
luarocks install --server=http://rocks.moonscript.org/manifests/Yonaba delaunay
##Installation
Copy the file delaunay.lua inside your project folder,
call it with require function. It will return the Delaunay module, keeping safe the global environment.
##Usage
The module provides 3 classes:
PointEdgeTriangle
It also provides a single function named triangulate. This function accepts
a variable list (vararg ...) of instances of class Point. Assuming those
points are the vertices of a convex polygon, it returns a table of instances of the class Triangle forming a Delaunay triangulation of the given polygon.
A basic code example:
local Delaunay = require 'Delaunay'
local Point = Delaunay.Point
-- Creating 10 random points
local points = {}
for i = 1, 10 do
points[i] = Point(math.random() * 100, math.random() * 100)
end
-- Triangulating de convex polygon made by those points
local triangles = Delaunay.triangulate(unpack(points))
-- Printing the results
for i, triangle in ipairs(triangles) do
print(triangle)
endSee the documentation for more details.
