Agenda for 11 January 2006 Shape Tools meeting

Attending: Roger , Craig, Jeff, Duygu, Bae Cheol, Ivo

Review prior weeks to do items

• [X] Craig - Test CGAL data structure
• [X] Craig - test use of CGALFaceSet in Minc and OFF reader to improve performance
• [-] Craig - Write OFF writer
• [X] Craig - add an IEdgeSet method to count edges w/o respect to orientation
• [X] Craig - add means to apply an AIR transform to point coordinates.
• [X] Craig - write ShapeCurvature application requirements.
• [X] Craig - write Euler number calculations.
• [X] Jeff - Continue work to apply custom transparencies to vertices (via a color map)
• [-] Jeff - add 'preferred view (transformation matrix)' menu to ShapeViewer
• [X] Jeff - addd per-shape transformation matrix values to scene file.
• [-] Jeff - Fix Fit to View bugs.
• [-] Roger - Example JNI interface to ShapeTools
• [X] BaeCheol - complete curvature calculation class
• [-] BaeCheol - write methods to create the test shapes used to test curvature.
• [-] BaeCheol - write ShapeCurvature application

New Business

• future directions

Discussed

• Irregular and CGAL Face set comparisons (minc obj)
  • CGALFaceSet works
  • pre-computation of Minc face adjacencies is slow

• ShapeViewer issues
  • Java 3d matrix transforms
    • Does java 3d have a method to determine the bounding box of an arbirary node of the scene graph
    • does java 3d have a way to set the rotation point (Jeff says no, it's always (0,0,0)
  • need to save/restore user's custom , preferred data rotation
• Future directions of this program
  • want to have programs created that have high visibility
  • maybe complete the Ucf tool set (port to Java)
  • help algorithm developers to move methods(from Matlab) into distributable (java) applications.
  • what data file formats to support
    • DXF mentioned (it's on the library wish list)
  • (Craig) talk with researchers to ascertain needs, promote use of ShapeTool applications

Decisions

To do for Next meeting

• [ ] Craig - Complete Write OFF writer.
• [ ] Craig - Yalin file format reader
• [ ] Craig - attend other CCB meetings to determine their needs
• [ ] Craig - continue work on 'native' ShapeTools file format
• [ ] Craig - talk to vinia to track problems with saving images from ShapeViewer
• [ ] Craig - research matrix math libraries (matlab, jsci)
• [ ] Craig - familiarize with JNI.
• [ ] Craig - talk with researchers to ascertain needs, promote use of ShapeTool applications
• [ ] Jeff - add 'preferred view (transformation matrix)' menu to ShapeViewer - save rotation matrix in user pref's file
• [ ] Jeff - Fix Fit to View bug
• [-] BaeCheol - finish write ShapeCurvature application
• [ ] Roger - work with Katherine , using java GC/ heap reports to reproduce and explain her java crashes.
