Hi all. <br><div class="gmail_quote"><br>I wrote a shell-script module <v.triangle> that is "front-end" for the famous <Triangle> utility (<a href="http://www.cs.cmu.edu/%7Equake/triangle.html" target="_blank">http://www.cs.cmu.edu/~quake/triangle.html</a>) of J.R. Shewchuk. I'm planning to add it to GRASS-Addons wiki page :)<br>
<br><Triangle> makes exact Delaunay triangulations, constrained Delaunay triangulations, conforming Delaunay triangulations and high-quality triangular meshes. On GIS terminology, it produces 2D TIN, optionally with "breaklines".<br>

It generally works but centroids in final TIN have "0" heights. Now I think about some hack to make the right centroids in all areas of TIN.<br>
<br>-----------------------------------------------------------------<br>Comparison of the one resulting TIN with the TIN produced in ArcView 3D Analyst see in linked PDF (<a href="http://dl.dropbox.com/u/42016908/ArcView_GRASS_TIN_breaklines.pdf">http://dl.dropbox.com/u/42016908/ArcView_GRASS_TIN_breaklines.pdf</a>) <br>
