In this issue, Dr. Jeff Baumes explores the VTK selection architecture used by ParaView and explains how this architecture can be used to manipulate data in any VTK-based application in his article “Selections in VTK”. Bradley Lowekamp’s article “IO Streaming in ITK” explains how out-of-core processing can be performed on extremely large datasets through simple filter modifications which support streaming in the execution of ITK’s pipeline. In “Writing a ParaView Reader Plug-in” Dr. Jeff Baumes provides a tutorial on writing reader plug-ins which allow users to open new file types from ParaView.
