###
### 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
###
### Make sure you understand the preceding notice before posting an issue. If you have 
### an issue not covered by the above, include your data-set with the problem.

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
