ofxAddons
A tool for subdividing a complex 2d shape into triangles.
README
ofxTrianglular
Easy to subdivide a complex 2d shape to triangles.
Support ``
OSX`(Xcode 6.0) `Windows`(Visual Studio 2012), and `Linux`(QtCreator, Ubuntu, Thanks for icq4ever).
Based on `Jonathan Richard Shewchuk`'s [triangle library]( http://www.cs.cmu.edu/~quake/triangle.html)

How to bulid
Based on OpenFrameworks, only need ofxTriangular, no other dependencies
To bulid example you need to include ofxUI and ofxXmlSettings in projectGenerator or added manually.
Replace the defalut project's `ofApp.cpp` + `ofApp.h` + `main.cpp`

Getting Started
Simplest way to init ofxTriangular`.
` c // set a boundary made by ofPolyline ofPolyline polyline
triangular.setBoundary(polyline);
If your 2d shape include some holes in it.
c // set a hole made by ofPolyline
// one ofxHole connect one point inside it. ofxHole hole; vector<ofxHole> holes;
// only if point(x, y) was inside the hole that you want to add. if(holeline.inside(x, y)) { hole.set(holeline, ofPoint(x, y)); holes.push_back(hole); }
triangular.setHoles(holes);
Subdivide complex 2d shape to triangles.
c // generate the triangle collections
triangles = triangular.triangulate();
If you want to render the triangle that ofxTriangular generated.
c // loop all of it if needed for(int i=0; i<triangles.size(); i++) { triangles[i].draw(); }
Shortage
The Option Tesselation` was enabled, but the effect of it was not obvious.(unless you set the option `tesselation` `0` compared with `600`)
Don't support advanced features like `iteration`, `constraint`. etc(haven't open the `API` yet).
Under some certain circumstances, `Debug` is much easier to crash than the `Release`.

Extreme Cases
Only in some exreme cases (complex nested boundary) that ofxTriangular runs on Windows was easier to crash than the OSX.
