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. (www.kitware.com) 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 VTK Community is upgrading its development process. We are doing this in response to the continuing and rapid growth of the toolkit. A VTK Architecture Review Board VTK ARB is being put in place to provide strategic guidance to the community, and individuals are being identified as leaders in various VTK subsystems.
Have a question or topic for the ARB to discuss about the future of VTK? First, please bring the topic to the VTK developers mailing list. If the issue is not resolved there or needs further planning or direction, you may enter a suggested topic for discussion.
We have started collecting works in progress as well as future ideas at NextGen. Please add anything you are working on, would like to collaborate on, or would like to see in the future of VTK!
