Hi Giovanni, A module for this would be really neat! I am not sure if this will be helpful, but here is what I have done in the past.
Set your region of interest of course. My notes indicate that I had to add an extra unit to the north and west region (not sure why). r.out.vtk -v input=dem@PERMANENT output=dem.vtk elevation=dem@PERMANENT # 'preserve normals' option kills Meshlab with DEM! r.out.vtk -v input=dem@PERMANENT output=dem.vtk elevation=dem@PERMANENT I then open dem.vtk in Paraview, and run the Delaney 2D filter (default options) save as .PLY file. Next I open the resulting .PLY file in Meshlab and run Quadric based edge collapse strategy - specify desired triangles, preserve normals and I save as .OBJ file. For my needs I choose "Preserve boundary of mesh”.
