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.

Example Usage (C++)

These are fully independent, compilable examples. There is significant overlap in the examples, but they are each intended to illustrate a different concept and be fully stand alone compilable.

Creating a dashboard submission

It is impossible for developers to test code on every operating system, compiler, and configuration. By creating a dashboard submission, you can help them find bugs that could be affecting many users but are transparent to some developers. The idea is to get the latest source code, compile it, and run a battery of tests - reporting any compile, build, and test errors to a system which very neatly arranges the results (http://www.cdash.org/CDash/index.php?project=VTK).

It is recommended to not use the same build you work with daily for you dashboard submission. If there is a problem with the nightly cvs, your code may not compile the next day!

To get started, create a new directory called /home/username/Dashboards/VTK. It does not actually have to be in this exactly directory, but this path will be used throughout this example to make the ideas concrete. cd to your new directory and run these commands to check out an initial version of VTK and data sets used for testing.

Here is an example cmake dashboard file.

You will probably want to submit a dashboard every night, so you can add a cronjob. Run 'crontab -e' and enter the following command <source lang="text"> 0 1 * * * ctest -S /home/username/Dashboards/VTK/dashboard.cmake -V > /home/username/Dashboards/VTK/dashboard.log 2>&1 </source>

This says "at 1:00 AM, every day, every month, run the dashboard tests and log verbose output to dashboard.log".
