8.2 Approach

ITK filters are mapped onto SCIRun modules via XML description files. Up to three XML files are required for each filter:

ITK Filter Description File

Description of a filter. Contains no SCIRun specific information.

SCIRun Filter Description File

Contains SCIRun specific information and include a reference to an ITK filter description file and an optional reference to a GUI description file.

GUI Description File

This file is optional. It describes a filter's GUI. A default GUI will be create if this file does not exist.

Software in the SCIRun build system automatically translates these XML files to SCIRun modules. XML files are described in ITK Filter Description, SCIRun Filter Description, and SCIRun GUI Description, respectively.
