Projects/Slicer3/2007 Project Week Support for Unstructured Grids

Return to Project Week Main Page

Mesh Quality Viewer Application.

Key Investigators

• Isomics: Steve Pieper, Alex Yarmarkov, Curtis Lisle
• BWH: Nicole Aucoin
• Kitware: Will Schroeder

Objective

Our objective is to integrate VTK Unstructured Grid datatypes into Slicer3.

Approach, Plan

The external collaboration "Automated FE Mesh Developmen"t brings Finite Element modeling and processes to the NA-MIC kit and Slicer3. The collaboration has developed standalone applications that use unstructured grids for rendering Finite Element models with colors assigned dynamically according to the out of the VTK Mesh Quality filter.

Our plan for the project week is to use the previously developed Mesh Quality Viewer to examine attributes needed for unstructured grid rendering in MRML classes. We will prototype extensions to MRML and to Slicer3 that allow us to read in and render unstructured grid meshes in Slicer3.
