Hi, I was wondering if there are any plans to enable filling of 2D polygons in NVIZ.
I'm using GRASS 7 but it appears that this feature currently isn't available. My workaround is summarised below, but perhaps someone could suggest a simpler approach. Overlaying a rasterised vector derived simply from v.to.rast does not give a good display in NVIZ given the topography of the base DEM layer, hence the method below which extracts DN values from the DEM. Summary: convert 2D polygon to raster (v.to.rast) create mask from latter raster add mask (r.mask) and create new layer using r.mapcalc extracting cell values from DEM: if( dem,dem,0 ) set colour of new raster using r.colors in NVIZ set Z position of new layer above DEM (e.g., 100) Cheers, Richard GRASS 7 Version: 57592 -- View this message in context: http://osgeo-org.1560.x6.nabble.com/Filling-2D-polygons-NVIZ-tp5076683.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
