NAME

       r3.mask  - Establishes the current working 3D raster mask.

KEYWORDS

       raster3d, mask, voxel

SYNOPSIS

       r3.mask
       r3.mask --help
       r3.mask   map=string    [maskvalues=val[-val][,val[-val],...]]     [--help]    [--verbose]
       [--quiet]  [--ui]

   Flags:
       --help
           Print usage summary

       --verbose
           Verbose module output

       --quiet
           Quiet module output

       --ui
           Force launching GUI dialog

   Parameters:
       map=string [required]
           3D raster map with reference values

       maskvalues=val[-val][,val[-val],...]
           List of cell values to be masked out

DESCRIPTION

       File map is used as reference file.  Cells in the mask are marked as  "mask  out"  if  the
       corresponding cell in map contains a value in the range specified with maskvalues.

       Before a new 3D-mask can be created the exisitng mask has to be removed with g.remove.
