NAME

       v.to.rast3  - Converts a vector map (only points) into a 3D raster map.

KEYWORDS

       vector, conversion, voxel

SYNOPSIS

       v.to.rast3
       v.to.rast3 --help
       v.to.rast3  input=name   [layer=string]   output=name column=name  [--overwrite]  [--help]
       [--verbose]  [--quiet]  [--ui]

   Flags:
       --overwrite
           Allow output files to overwrite existing files

       --help
           Print usage summary

       --verbose
           Verbose module output

       --quiet
           Quiet module output

       --ui
           Force launching GUI dialog

   Parameters:
       input=name [required]
           Name of input vector map
           Or data source for direct OGR access

       layer=string
           Layer number or name
           Vector features can have category values in different layers. This  number  determines
           which layer to use. When used with direct OGR access this is the layer name.
           Default: 1

       output=name [required]
           Name for output 3D raster map

       column=name [required]
           Name of attribute column (data type must be numeric)

DESCRIPTION

       v.to.rast3 converts a GRASS 3D vector point map to a GRASS 3D raster map.

NOTES

       When  converting  from  a  3D  vector  point  layer  to  a 3D raster map a vector point is
       converted into a single 3D raster cell (voxel) representing the  location  of  the  vector
       point.  As 3D raster cell value the database  attribute of the vector point is stored with
       floating point precision.

       This screenshot shows the result  of  the  v.to.rast3  test.
       Visualized  are  the  cube  of  the grass region, the vector
       points as black dots and the voxel cells as wireframe model.
       Only cells with non-null values are shown.
