    114114 * Go to "Optional" tab and activate "Trace elevation" to make the house bottom line follow the terrain and select "elev_lid792_1m@PERMANENT" as "Elevation map", then "Run". This creates the 3D house vector block.

     118Since the new NVIZ within wxPython doesn't yet support 3D vectors, we use the common !TclTk NVIZ in the shell terminal:
     119
     120{{{
     121  g.region rast=elev_lid792_1m -p
     122  nviz elevation=elev_lid792_1m color=ortho_2001_t792_1m vector=house3D
     123}}}
     124
     125 * Move the puck to change the viewpoint,
     126 * increase the raster resolution in "Visualize" -> "Raster surfaces" -> "Resolution fine" to 1 (the smaller the number, the higher the resolution).
