[postgis-devel] ST_VoronoiDiagram first cut

[Brian M Hamlin]

Hi devs --
 
  I forked the PostGIS git repo and merged in stubs for an ST_VoronoiDiagram() function.. 
( the call is already ported in GEOS, so the task at hand is to expose it in PostGIS 2.2)
 
  If the function is added to PostGIS 2.2, I can commit to writing the tests and see that they pass. 
(I have not added the new internals yet, nor the test contents -- this is a first try.. )
 
 
You can take a look at the fork here :
 
    https://github.com/darkblue-b/postgis
 
Here is the `git status` result, just before the push:

As reference material, I have JTS 1.13 in Eclipse "kepler" in a decent state (classpaths etc)
on the Java side,  and GEOS 3.5dev PostGIS 2.2 trunk, in several build environments.
