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:
- Initialize CDT with a simple polyline (this defines the constrained edges)
- Add holes if necessary (also simple polylines)
- Add Steiner points
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. The only easy day was yesterday; have a nice day.
TESTBED INSTALLATION GUIDE
Core poly2tri lib:
- Standard Template Library (STL)
waf is used to compile the testbed. A waf script (86kb) is included in the repositoty.
Building the Testbed
./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>
./build/p2t testbed/data/dude.dat 300 500 2 ./build/p2t testbed/data/nazca_monkey.dat 0 0 9 ./build/p2t random 10 100 5.0 ./build/p2t random 1000 20000 0.025
