3D raster map with reference values - maskvalues=val[-val][,val[-val],...]

DESCRIPTION
r3.mask facilitates the creation of a raster3d "MASK" map to control raster3d operations. The raster3d map is used as the reference map. Cells in the mask are marked as "mask out" if the corresponding cell in map contains a value in the range specified with maskvalues.
NOTES
Before a new 3D-mask can be created the existing mask has to be removed with g.remove.
