The Visualization ToolKit (VTK) is an open source, freely available software
system for 3D computer graphics, image processing, and visualization used by
thousands of researchers and developers around the world. VTK consists of a
C++ class library, and several interpreted interface layers including Tcl/Tk,
Java, and Python. Professional support and products for VTK are provided by
Kitware, Inc. VTK supports a wide variety of visualization algorithms
including scalar, vector, tensor, texture, and volumetric methods; and
advanced modeling techniques such as implicit modelling, polygon reduction,
mesh smoothing, cutting, contouring, and Delaunay triangulation. In addition,
dozens of imaging algorithms have been directly integrated to allow the user
to mix 2D imaging / 3D graphics algorithms and data. The design and
implementation of the library has been strongly influenced by object-oriented
principles. VTK has been installed and tested on nearly every Unix-based
platform, PCs (Windows 98/ME/NT/2000/XP), and Mac OSX Jaguar or later.
