CCB Shape Tools Program - 10 August 2005

Agenda

• Status
  • ShapeTools Library
  • ShapeViewer
  • R Tools
• Reviews of java 3d book and geometry library
  • http://java.sun.com/products/java-media/3D/collateral/
  • http://www.javaview.de/
  • http://jvisual3d.sourceforge.net/
  • http://sourceforge.net/projects/jgv
  • http://sourceforge.net/projects/jmath/
• Release Dates - will we make it ? what problems exist ?
  • Alpha v1.1.0a1 - 10 August 05
  • Testing - 17 August 05
  • Fix problems / release v1.1.0a2

Discussed

• Should we distribute the next release of the viewer yet
• Viewer shows surfaces in more detail than prev. viewers. They look odd because of this.
• Slow loading on a Macintosh
• Cornelius may not have time to represent ShapeViewer
• Review of geometry tools - Summary - only one might be useful (JavaView) but it may not be freely redistributed.
• JavaView and jVisual3D do not require java3d & so should work on an SGI.
• Support of alternate viewer frameworks by ShapeViewer (Jeff likes JavaView)
• Usefulness of having an easily used viewer that can be called from library code.
• definition and use of implicit surfaces (a 3d grid of numbers).
• problems loading a 'diamond ucf'.
• next file format to support might be DXF.
• far future wish list: implement a java SSH based remote filesystem browser.

Decisions

• don't distribute ShapeViewer until bugs and features are complete, and tested.
• complete java3d version of viewer before considering support for other viewer frameworks.
• R Interface - no change since last meeting.

Java library Reviews

JavaView A standalone application. no clearly evident separable library. Documentation & Source describes use of application (viewer), not library. - cs.

Good, but not freely distributable - qma

Jvisual3d Includes Gui , little or no geometry operations, mostly different object types -cs.

Too simple -qma

Jmath Project has not released any files - cs.

JGV An applet with simple shape classes. Possibly useful to Jeff, otherwise much to simple -cs

To Do for Next Week

• [X] Craig - establish Bug Report pages on the Wiki
• [X] Craig - Minc Writer
• [ ] Craig - Ucf data attributes
• [ ] Craig - begin surface resamplers if time permits
• [ ] Craig - Minc OBJ DOM translations if time permits
• [ ] Craig - look into the problem loading the 'diamond ucf'
• [ ] Jeff - distribute a scene file that refers to a URL for testing
• [ ] Jeff - install an Applet and distribute it's URL for testing.
• [ ] Jeff - improve speed of loading on a Macintosh
• [ ] ALL - Test ShapeViewer on all platforms. - Make Notes
