The difference exists. <v.delaunay> don't work with "breaklines", e.g. with constrained Delaunay triangulation, but <Triangle> does (also conforming triangulation & quality meshing). About constructing TIN's with "breaklines": -- http://www.ian-ko.com/resources/triangulated_irregular_network.htm -- http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#/What_is_a_TIN_surface/006000000001000000/ One of problems is "soft" breaklines that not change surface continuity -- I experimented with them in GRASS, but not through <Triangle>.. P.S. Just try to run <v.triangle> P.P.S. I will make a page on GRASS-Wiki to explain the work of this module :) -- View this message in context: http://osgeo-org.1560.n6.nabble.com/v-triangle-module-to-produce-TIN-with-breaklines-using-Triangle-utility-tp4903158p4904263.html Sent from the Grass - Users mailing list archive at Nabble.com. _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
