Hello everyone, A few weeks ago the issue on creation of 3D TINs in GRASS from 3D points came out again, and after some trials I managed to do it. Since it might be of general interest, here it goes:
- you need to install Paraview (www.paraview.org) and MeshLab (http://meshlab.sourceforge.net/) 1 - Export your 3d points as a VTK file; 2 - In Paraview, open the vtk file, click on Apply, then go to Filters-Alphabetical-Delaunay 2D (need to click apply again). click on the name of the just-created mesh and go to file-save data. Save it as a PLY file. 3 - Open the PLY in MEshLab and save as a DXF. If you open the dxf in a text editor, you will see the lovely 3DFACE. :) If imported it back into GRASS, it will be imported as FACES. nice. good luck!
