### Parameters:

input=name [required]
  Name of V5D raster file to be imported
output=name [required]
  Name for output 3D raster map
null_value=string
  String representing NULL value
  Default: none
type=string
  Data type used in the output raster3d map
  Options: default, double, float
  Default: default
precision=string
  Number of digits used as mantissa in the internal map storage, 0 -23 for float, 0 - 52 for double, max or default
  Default: default

  Default: default

## DESCRIPTION

r3.in.v5d imports 3-dimensional files (i.e. the V5D file with one variable and one time step). Otherwise, only first variable and timestep from 4/5D V5D file will be imported.

Vis5D is a system for interactive visualization of large 5D gridded data sets such as those produced by numerical weather models. The user can make isosurfaces, contour line slices, colored slices, volume renderings, etc. of data in a 3D raster map, then rotate and animate the images in real time. There's also a feature for wind trajectory tracing, a way to make text anotations for publications, support for interactive data analysis, etc.
