VTK (The Visualization Toolkit) is a software system for 3D Computer Graphics and Visualization. Vtk includes a textbook published by Prentice-Hall, a C++ class library, and a Tcl implementation based on the class library. The design and implementation of the library has been strongly influenced by object-oriented principles. The graphics model in vtk is at a higher level of abstraction than rendering libraries like OpenGL or PEX. This means it is much easier to create useful graphics and visualization applications. In vtk applications can be written directly in C++ or in Tcl, a interpretive language developed by John Ousterhout. In fact, using Tcl and Tk, a graphical user interface toolkit based on Tcl, it is possible to build useful applications really, really fast. Finally, the software is a true visualization system, it doesn't just let you visualize geometry. Vtk supports a wide variety of visualization algorithms including scalar, vector, and tensor visualization, and advanced modeling techniques like implicit modeling, polygon reduction, and Delaunay triangulation.
