Home < 2013 Summer Project Week:Parameter heirarchy

Key Investigators

  • Queen's: Adam Rankin
  • Queen's: Andras Lasso
  • Queen's: Tamas Ungi

Objective

The goal is to develop a module that creates and utilizes a new hierarchy based on definable parameters. This will allow us to characterize data by time.

Approach, Plan

  • Review existing time hierarchy discussion
  • Learn technical details about hierarchies
  • Discuss architecture of a flexible, abstract parameter hierarchy
  • Implement said hierarchy

Progress

  • Discussed approach to be taken, concerns regarding performance
  • Node count can explode into the thousands, performance analysis needed
    • Initial test performance analysis run, results concerning
      • Create hierarchies with 1500 and 7000 nodes, observed
      • Create hierarchy with 250 * 5 (1 volume 512x512x4byte, 4 transforms per frame) nodes
        • Slider in widget tied to logic to replace current view volume contents with the contents of the frame indexed by slider value
          • Deep copy used
        • Allocate nodes, add to scene WITH BATCH PROCESSING
        • Able to drag slider, occasional stuttering
        • i7-2640M, 6GB RAM, 2nd gen SSD
        • Run1 250
        • Run2_250
        • Run3_500
        • Run4_1000

To do:

  • Implement importer/exporter for MHA
  • Discuss approach to performance, currently performance features are optional

Delivery Mechanism

This work will be delivered to the NA-MIC Kit as a Slicer module in the SlicerIGT extension.
