Shape Tools meeting / 2 Nov. 2005

Agenda

• Report on prior week's to do list activities:
  • [X] Craig - ask whether we can use production server certificates to sign applets.
  • [X] Craig - describe Color Bar behaviours to Jeff (done via Mantis bug).
  • [X] Craig - add InterpolateContour code to CVS
  • [X] Craig - add ShapeDistance code to CVS
  • [X] Craig - update ShapeTools CVS to v. 1.1.0
  • [X] Craig - add InterpolateContour to Loni Software Download
  • [X] Craig - add OFF file format reader to ShapeTools
  • [X] Craig - send ref. to CVS clients to Alex and Daniel.
  • [X] Craig - create CD to distribute at CCB meeting.
  • [X] Craig - add ShapeViewer to Wiki distribution
  • [X] Craig - update ShapeViewer loni software download.
  • [ ] Jeff - add setTimeout(int seconds) and getTimeout() : int to VFSB public API
  • [ ] Jeff - add a way for a user to change the timeout period of the VFSB
  • [ ] Jeff - update ShapeViewer CVS to v. 1.1.0
  • [ ] Jeff - add VFSB code to CVS
  • [ ] Jeff - remove VFSB from applet. Applet will enable only "Load URL" menu.
  • [ ] Jeff - add -version command line argument to ShapeViewer
• Meeting Presentation
  • Product Sheet review
  • CD Rom Review
  • Future plans
• Other
  • Implicit surface paper

Discussed

• Virtual File System Brower now times out at 30 seconds, instead of hanging the application.
• CCB should have it's own Certificate. Now would be a good time to request this from Rico, cost is $200-$300/yr.
• The shape viewer applet now displays only files explictly listed in the web page hosting the applet.
• The viewer applet is is not included in either CDROM or Software Download distributions.
• Shape Viewer color map issues still exist.
• We'll need an OFF format writer, as it is widely used.
• Future work might include
  • simple viewer class, callable from java, Matlab, C, C++
  • calculations to support determination of neighbors using geodesic distances
  • calculations to find point on a (triangulated) suface that is closet to a given point.
  • support for parallel processing of computationally intensive algorithms.
  • tools to compute the curvature of a surface at each surface vertext.
• Dates of future import for CCB
  • April 2006 - finalize all CCB year 1 efforts.
  • May 2006 - CCB Advisory board meeting
• Estimates of time & effort needed to fully document ShapeTools library.
• A neuroimaging paper would publicize the tools and answer questions about their use.
• "Digital Geometry Processing" topics cover many items of interest to us.
• Initial interest in ShapeTools is likely to focus on the file readers and writers it provides.
• Use of Mantis to track problems
• A ShapeViewer presentation to the CCB using the LONI Dive and with an (outdoor) reception following.
• An effective way to develop documentation is to answer all questions by referering the questioner to (updated) written documentation.

Decisions

• Distribute the shape viewer applet as a software product separate from the ShapeViewer application.
• Implement an OFF format shape writer

To Do for Next Meeting

• [ ] - Craig - Off writer

• [ ] - Craig - test pipeline wrapper for ShapeViewer
• [X] - Craig - define a starter project for Bae Cheol.
• [X] - Jeff - add ShapeViewer code to CVS if not already done.
• [X] - Jeff - add VFSBrowser code to CVS if not already done.
• [ ] - Jeff - respond to ShapeViewer bug reports.
