| 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.

| ===ItkVtkGlue===
| |
| ITK and VTK are very separate toolkits - ITK for image processing and VTK for data visualization. It is often convenient to use the two together - namely, to display an ITK image on the screen. The ItkVtkGlue kit serves exactly this purpose. Also provided inside ItkVtkGlue is a QuickView class to allow a 2 line display of an ITK image.
| |
| | |
| If you download the entire ITK Wiki Examples Collection, the ItkVtkGlue directory will be included and configured. If you wish to just build a few examples, then you will need to [http://gitorious.org/itkwikiexamples/itkwikiexamples/blobs/raw/master/ItkVtkGlue.tar.gz download ItkVtkGlue] and build it.
