VTK Files

VTK is a file format used by the Visual Toolkit.

Note that the Visual Toolkit can read and write graphics information in a variety of formats. However, for completeness, the designers included a native VTK format.

VTK File characteristics:

• ASCII or binary;

Programs to convert a VTK file to another format:

• vtkBYUWriter can write a VTK image to MOVIE.BYU polygon file.
• vtkIVExporter can export a VTK image to Open Inventor.
• vtkIVWriter can write a VTK image to an Open Inventor file.
• vtkOBJExporter can export a VTK image to an OBJ file.
• vtkPNMWriter can write a VTK image to a PNM file (including PBM, PGM and PPM).
• vtkSTLWriter can write a VTK image to an STL Ascii or STL binary file.
• vtkTIFFWriter can write a VTK image to a TIFF file.
• vtkVRMLExporter can write a VTK image to VRML file.

Programs to convert a file to VTK format:

• vtk3DSImporter can import a 3DS file into VTK.
• vtkBYUReader can read a MOVIE.BYU polygon file into VTK.
• vtkPLOT3DReader can read a PLOT3D file into VTK.
• vtkPNMReader can read a PNM file (including (including PBM, PGM and PPM) into VTK.
• vtkSTLReader can read an STL Ascii or STL binary file.

Sample VTK Files:

• dec.vtk, Data values for stock;
• ge.vtk, Data values for stock;
• gm.vtk, Data values for stock;
• hello.vtk, Stroked lines spell "hello";
• ibm.vtk, Data values for stock;
• k.vtk, VTK output;
• polyex.vtk, Cube example;
• texthres.vtk, Texture map for thresholding data (use boolean textures for 2D map);
• texthres2.vtk, Texture map for thresholding data (use boolean textures for 2D map);
• t.vtk, VTK output;
• ugridex.vtk, an example of an unstructured grid;
• vtk.vtk, Line representation of "VTK";
• v.vtk, VTK output;
