Voxel Meshing Module
From NAMIC Wiki
Home < Voxel Meshing Module
Objective:
- Develop an initial framework for integration of Meshing modules into the NA-MIC kit
Progress:
- Base code has been developed as an Execution Model for Slicer3
- Orientatation issues wrt Slicer3 and ITK coordinate systems have been determined
- Extraction of surfaces nodes has been implemented to view results in Slicer3
To Do:
- Slicer3 needs to add support for loading and manipulating VTK Unstructured Grids
- Source Code needs to be added to Slicer3
Key Investigators:
- Iowa: Nicole Grosland, Vincent Magnotta, Ritesh Bafna

Description: This program will convert an image into a hexahedral mesh using the voxels as the hexahedral elements. This is is typically done for only a portion of the image and thus a binary image from a segmentation may be used to define the region for meshing. Since these meshes may be fairly large the user is allowed to downsample the image by an integer value. Currently this must be odd.
This tool was developed as part of an NIH NA-MIC Collaboration Grant EB005973.
