Hi again dear grass users, fiddling with point cloud data, I notice a capability of r.out.xyz which is neither documented nor allowed from the gui interface, at least in GRASS 6.4.
In order to produce an ascii pointcloud file following this pattern : x y z r g b (i.e. each point of the cloud is described by its coordinates picked from an elevation raster and a RGB value picked from an imagery raster) I ran several r.out.xyz commands, then joined the result in a single file cloud.dat by piping three join commands. Anyway, later I accidentally typed : r.out.xyz fs=" " in=elev,map.red,map.green,map.blue out=cloud.dat ... and it produced the right pointcloud in one go. Perhaps it can be useful (tell me if I miss something rhedibitory with this usage) : - to update the module documentation - to allow multiple input selection from the gui interface. Yours, Vincent. _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
