.br
Name of input vector map
.br
Or data source for direct OGR access
.IP "\fBlayer\fR=\fIstring\fR" 4m
.br
Layer number or name
.br
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.

.br
Name for output 3D raster map

.br
Name of attribute column (data type must be numeric)
.SH DESCRIPTION
\fIv.to.rast3\fR converts a GRASS 3D vector point map to a GRASS 3D raster map.
.SH 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.
