CCB Shape Tools Meeting - 7 September 2005

Agenda

• Review To Do from Last Meeting
  • [X] Craig - investigate spline interpolation - why doesn't order 1 mimic Paul's method ?
  • [X] Craig - contact JSpline+ authors re: copyright
  • [ ] Craig - write methods to create sufaces from 'diamond' ucf files.
  • [X] Craig - test out-of-memory while reading large obj/'
    • CenterOfUcfJavaSource used to test read: Cortex, E2333S4I_prEw_BIG_whole_Rhem_blend.ucf : ok
  • [90%] Craig - write binary obj
  • [ ] Craig - write a section of ShapeTools user guide
  • [90%] Jeff - continue testing and fixing ShapeViewer
  • [X] Jeff - display diamond ucf surfaces.
  • [ ] ALL - test current ShapeViewer
• Discuss Issues
• Make Decisions

Issues Discussed

• InterpolateContour - treatment of duplicate points. Remove adjacent duplicate preferable to alteration.
• Copyright restrictions on JSpline+. We may redistribute for non-commercial use. We may wish to remove JSpline from the ShapeViewer to simplify licensing of ShapeViewer.
• ShapeViewer almost ready for lab release of v1.0.0b0 (beta)
• make ShapeViewer and InterpolateContour available via a twiki page
• Utility of pipeline modules for ShapeViewer, InterpolateContour and ShapeDistance (when written).
• Value of measuring various types of distances between surfaces
• Need for a simple shape file format.
• Meeting & availability for the next few weeks.

Decisions

• Write a tool to compute distance between vertices of a shape and store the values in an attribute
• Distribute current set of tools to lab for beta testing.
• Next two meetings; 11a-12p Wed, Sep 14 ; 1p - 2 p, Thu., Sep 22.

To Do for Next Meeting

• [X] Craig - complete binary obj writer
• [X] Craig - add -remove option to InterpolateContour - removes duplicate, adjacent vertices in a contour.
• [ ] Craig - ShapeIO metadata conversions
• [ ] Craig - ShapeDistance tool - Store Euclidean distance in an attribute, save as Ucf.
• [ ] Craig - create and publicize LONI download web page for current set of applications.
• [ ] Craig - build ShapeViewer applet from code to Jeff will send.
• [ ] Jeff - send craig code with which to buid applet
• [ ] Jeff - clean up remaining ShapeViewer issues
• [ ] Jeff - create pipeline modulds for ShapeViewer, InterpolateContour and ShapeDistance
• [ ] All - test web page containing embedded ShapeViewer applet.
