Project Description

Objective

  • Understand how the rendering is done in a stand alone tool (3DMeshMetric) that creates color-coded table for vtk files, in order to be able to update the stand alone tool to be part of the Slicer's extensions.

Approach, Plan

  • Work in progress

Progress

  • Discussion on Tuesday morning:
    • looked at a vtk model with scalar overlay in Population Viewer and Slicer
    • defining color mappings via point scalar value and an RGB
      • Population Viewer uses an xml file format to save
      • Slicer doesn't have a prodecural color node storage node
    • identified some issues in Slicer:
      • missing a red through green to blue continuous color table
      • in the Models module, resetting the color table and active scalar is buggy
      • in the Colors module, range is not updated to the scalar bar
    • Medium term Slicer to do list:
      • color transfer function gui element in the Colors module
      • procedural color node storage node
        • support csv and xml?
  • Bug fixes in Slicer
  • Enhancements to Slicer
  • To do:
    • investigate the volume rendering module color transfer widget and volume properties node and storage node and see how they can be used with the procedural color nodes
