 D widgets are transitory and are designed to be created by applications just when needed.  We discussed a strategy where some of the information from a widget representation could be stored in MRML, but the widget interaction itself will be instantiated outside of the MRML tree.  Follow-on discussions are planned between the Jan 2008 and June 2008 project weeks.

 <h1>Progress</h1>
 ====Jan 2008 Project Week====
-A class of MRML nodes to correspond to VTK-style 3D widgets were created (based on fiducials) as an experiment during this project week.  It was decided that this was not the way to integrate 3D widgets because of its inconsistency with MRML storing geometry and dataset state variables.  3D widgets, in contrast, are transitory and are designed to be created by applications just when needed.  The MRML-based 3D widgets node design was abandoned.

 <h1>Objective</h1>
-To integrate 3D W widgets into Slicer3.
+Several different module developers have asked  to insert and operate with VTK-style 3D widgets in the Slicer 3D view window.  This project will study the implications of different ways to insert 3D widgets and how the design of VTK 3D widgets can best interact with Slicer's MRML tree.   Widget interaction may require an extension to the MRML observer paradigm.
