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
  • Models module Display Scalars
  • Model displayable manager
