Man Pages Grass User's Manual - Converts a vector map (only points) into a 3D raster map.

input=name [required]
Name of input vector map
Or data source for direct OGR access
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) converts a GRASS 3D vector point map to a GRASS 3D raster map.

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 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.
