I'm not sure that this is supposed to work. Actually, I was surprised  
that I could display 3D points without a raster surface using the nviz  
-q method. Note that the parameter descriptions call both vector and  
point files as "overlay" maps. That is, it is assumed that they will  
overlay a surface.

Parameters:
   elevation   Name of raster map(s) for Elevation
       color   Name of raster map(s) for Color
      vector   Name of vector lines/areas overlay map(s)
      points   Name of vector points overlay file(s)
      volume   Name of existing 3d raster map
        path   Set alternative panel path
      script   Execute script file at startup
       state   Load previously saved state file
