Since there are no Input validation of the data given for triangulation you need
|
2012-08-21 17:32:58 +02:00
|
|
|
to think about this. Poly2Tri does not support repeat points within epsilon.

|
|
|
* If you have a cyclic function that generates random points make sure you don't
|
|
|
|
add the same coordinate twice.
|
|
|
|
* If you are given input and aren't sure same point exist twice you need to
|
|
|
|
check for this yourself.
|

|
|
|
* Only simple polygons are supported. You may add holes or interior Steiner points
|
|
|
|
* Interior holes must not touch other holes, nor touch the polyline boundary
|
|
|
|
* Use the library in this order:
|
|
|
|
1. Initialize CDT with a simple polyline (this defines the constrained edges)
|
|
|
|
2. Add holes if necessary (also simple polylines)
|
|
|
|
3. Add Steiner points
|
|
|
|
4. Triangulate

[waf](http://code.google.com/p/waf/) is used to compile the testbed.

|
|
```
|

|
|
p2t <filename> <center_x> <center_y> <zoom>

Random distribution of points inside a consrained box:
|
|
|
|
```
|
|
|
|
p2t random <num_points> <box_radius> <zoom>
|
|
|
|
```
