Hi, I'm not sure to understand the difference between your v.triangle and the v.delaunay ( http://grass.osgeo.org/grass64/manuals/html64_user/v.delaunay.html) already in grass core ... for what I see in your pdf exemple, it seems that your new module is giving almost the same result as v.delaunay would do ...
can you explain the differences ? I like to learn new things in grass ;) cheers, Sylvain 2012/4/20 Alexander Muriy <[email protected]> > Hi all. > > I wrote a shell-script module <v.triangle> that is "front-end" for the > famous <Triangle> utility (http://www.cs.cmu.edu/~quake/triangle.html) of > J.R.
