C++, Tcl and Python example programs/scripts for VTK

 The Visualization Toolkit (VTK) is an object oriented, high level
 library that allows one to easily write C++ programs, Tcl, Python and
 Java scripts that do 3D visualization.
 .
 This package contains examples from the VTK source. To compile
 the C++ examples you will need to install the vtk-dev package as well.
 Some of them require the libqt4-dev package.
 .
 The Python and Tcl examples can be run with the corresponding packages
 (python-vtk, tcl-vtk).
