Objective
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.
The Slicer3 infrastructure is being extended to support Unstructured Grid datatypes for meshing processes, and the functions from the Univ. of Iowa workflow are being incorporated incrementally during the course of this project.
Approach, Plan
The Univ. of Iowa Finite Element collaboration project has added 3D widgets using direct manipulation and custom callbacks. We will discuss the strengths and weaknesses of this approach as a case study.
At the end of the week, our objective is to have additional clarity on the design approach that modules should take when they want to interact with 3D widgets in Slicer3.
