+description = """The Visualization Toolkit (VTK) is an open-source, freely available software system for
+ 3D computer graphics, image processing and visualization. VTK consists of a C++ class library and several
+ interpreted interface layers including Tcl/Tk, Java, and Python. VTK supports a wide variety of visualization
+ algorithms including: scalar, vector, tensor, texture, and volumetric methods; and advanced modeling techniques
+ such as: implicit modeling, polygon reduction, mesh smoothing, cutting, contouring, and Delaunay triangulation."""
