I exported the TIN with Geoprocessing->TIN->Conversion-TIN to Shapes. This allows me to export<br />- points<br />- edges<br />- triangles<br />- centroids of triangles<br />- Voronoi polygons<br /><br />as separate shapefiles. <br /><br />Now I'm wondering how to theme the outputs. QGIS does not seem to have facility to make a 3D or 2.5D representation of these outputs. Suggestions?<br /><br />Thanks for your work on this. SAGA is indeed powerful but not well-documented.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-4741970181714760187.post-36116723533004726002017-05-11T18:24:12.544+01:002017-05-11T18:24:12.544+01:00I found using 'Mark Highest Neighbour' giv...I found using 'Mark Highest Neighbour' gives me a nicer TIN, but still not an accurate representation.Snomihttps://www.blogger.com/profile/05063736034452860444noreply@blogger.comtag:blogger.com,1999:blog-4741970181714760187.post-53123815289013607772016-09-10T19:49:58.447+01:002016-09-10T19:49:58.447+01:00I use SAGA from the command line on MacOS X.
