Tcl bindings 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 provides the shared libraries and executable that enable one to use
 VTK from Tcl/Tk scripts. You will need Tcl/Tk and vtk installed to use
