|
### 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.
