NAME
r3.out.vtk - Converts 3D raster maps (G3D) into the VTK-Ascii format
SYNOPSIS
r3.out.vtk
r3.out.vtk help
r3.out.vtk [-mp] input=string[,string,...] [output=string] [null=float] [elevscale=float]
Flags:
- -m
- Use G3D mask (if exists) with input maps
- -p
- Create VTK pointdata instead of VTK celldata (celldata is default)
Parameters:
- input=string[,string,...]
- 3dcell map(s) to be converted to VTK-ASCII data format
- output=string
- Name for VTK-ASCII output file
- null=float
- Float value to represent no data cell
- Default: -99999.99
- elevscale=float
- Scale factor for elevation
- Default: 1.0
DESCRIPTION
Outputs G3D maps in VTK-ASCII format. Map's are
valid G3D map's in the current mapset. output is the name of
an VTK-ASCII file which will be written in the current working directory.
If output is not specified then stdout is used.
The module is sensitive to region settings (set with g.region).
NOTES
This filter generates a structured grid with celldata (default) or pointdata and put
this in a simple VTK-ASCII file. Nor XML or
binary output are supported. It is possible to choose more then one G3D map
to be written in the VTK-ASCII file. Each celldata is named like the G3D map it represents.
You can visualize this file with the
VTK Toolkit,
Paraview and
MayaVi which are based on VTK.
If you have a G3D map with partly no data, use the threshold filter in paraview to
visualize the valid data. Just filter all data which is greater/lesser than the
choosen null value in the VTK-ASCII file.
