# 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](https://github.com/icq4ever)).

Based on ```Jonathan Richard Shewchuk```'s [triangle library]( http://www.cs.cmu.edu/~quake/triangle.html)

### How to bulid

* Based on [OpenFrameworks](http://openframeworks.cc/), only need [ofxTriangular](https://github.com/BentleyBlanks/ofxTrianglular), no other dependencies

* To bulid example you need to include [ofxUI](https://github.com/rezaali/ofxUI) and [ofxXmlSettings](https://github.com/openframeworks/openFrameworks/tree/master/addons/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.
