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.
