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 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. In addition, dozens of imaging algorithms have been directly integrated to allow the user to mix 2D imaging / 3D graphics algorithms and data.
The VTK integration adds exciting new possibilities to the MeVisLab environment, almost all VTK algorithms are available as MeVisLab modules and even the combination of Open Inventor and VTK modules is possible.
About 1000 additional MeVisLab modules are based on algorithms from the VTK project.
