VTK

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.

Development Process

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.

Learning VTK

• Examples - Short code examples demonstrating basic functionalities of VTK.
• Tutorials - Slightly longer than the examples, these tutorials explain concepts and demonstrate more complicated tasks in VTK.

Wrapping

• Java
• Python

Things that are ready to add to VTK

• Collision detection (vtkCollisionDetectionFilter) for computing the intersection of 2 polydata's - http://www.bioengineering-research.com/vtk/vtkCollisionDetectionFilter.htm
• vtkBezierSurfaceWidget from VTK Designer (http://sourceforge.net/projects/vtkdesigner/) to fit bezier surfaces from a point set
• Point set processing classes - http://www.insight-journal.org/browse/publication/708

Things that VTK is missing

• Approximate nearest neighbors algorithm
• Stratified sampling or similar mesh sampling (http://www.tecgraf.puc-rio.br/~diego/academic/phd/597d/sample/)
