Since there are no Input validation of the data given for triangulation you need
|
||
|
|
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
|
||

TESTBED INSTALLATION GUIDE
|
||
|
|
===========================
|
||
|
|
|
||
|
|
Dependencies
|
||
|
|
------------
|
||
|
|
|
||
|
|
Core poly2tri lib:
|
||
|
|
|
||
|
|
* Standard Template Library (STL)
|
||
|
|
|
||
|
|
Testbed:
|
||
|
|
|
||
|
|
* gcc
|
||
|
|
* OpenGL
|
||
|
|
* GLFW (http://glfw.sf.net)
|
||
|
|
* Python
|
||
|
|
|
||
|
|
[waf](http://code.google.com/p/waf/) is used to compile the testbed.
|
||
|
|
A waf script (86kb) is included in the repositoty.
|
||
|
|
|
||
|
|
Building the Testbed
|
||
|
|
----------------------------------------------
|
||
|
|
|
||
|
|
Posix/MSYS environment:
|
||
|
|
```
|
||
|
|
./waf configure
|
||
|
|
./waf build
|
||
|
|
```
|
||
|
|
|
||
|
|
Windows command line:
|
||
|
|
```
|
||
|
|
python waf configure
|
||
|
|
python waf build
|
||
|
|
```
|
||
|
|
|
||
|
|
Running the Examples
|
||
|
|
----------------------------------------------
|
||
|
|
|
||
|
|
Load data points from a file:
|
||
|
|
```
|
||
|
|
p2t <filename> <center_x> <center_y> <zoom>
|
||
|
|
```
|
||
|
|
Random distribution of points inside a consrained box:
|
||
|
|
```
|
||
|
|
p2t random <num_points> <box_radius> <zoom>
|
||
|
|
```
|
||
|
|
Examples:
|
||
|
|
```
|
||
|
|
./p2t dude.dat 300 500 2
|
||
|
|
./p2t nazca_monkey.dat 0 0 9
|
||
|
|
|
||
|
|
./p2t random 10 100 5.0
|
||
|
|
./p2t random 1000 20000 0.025
|
||
|
|
```
