What

Slicer 4 review and programming sprint

When

July 19, 10 am -21, 4pm 2011

Who

Slicer 4 core programmers

Where

Demo room, 2nd floor, 1249 Boylston Street, Boston, MA

Why

• Identify roadmap for a Slicer 4 product release for the Nov 27-Dec.2 RSNA demos at the 3DSlicer Booth

Work on

Main Topics

• Critical Features
• Bug fixes
• Download setup and integration with the existing Slicer website

Priority TBD

UI

SlicerColorSelector

• Reformat capabilities: We need a widget and possibly a slider based interface.
• Main GUI
  • face lift for the Slice viewers: reduce permanent non-image components. Reduce the number and depth of submenus.
  • 3D viewers should have similar appearance to slice viewers
• Update tutorials
  • After main gui
  • Using GUI Testing
• Volume rendering transfer function
  • Jittery, and banding
  • Threshold
  • Better appearance of the elements of the transfer function. They look ugly and are not antialiased. Check the graph in Ohloh and mouse over it. Looks much nicer! (according to the page source, the charts are made with HighCharts)
  • Group selection and shifting
• Color selector
  • the default color selector should be the one that is slicer customized, not the Qt default.
  • add search function to the labels

Under the hood

• GPU Volume Rendering
  • Support for ATI and MAC
  • How many GPU render engines to support/provide?
    • Ron says: I just need a single one that works for flythroughs and can handle the combination of volume rendering, cross-sections, surface models, annotations
• hierarchies
  • display: the current display is confusing.
  • drag and drop capability
• Annotations
  • vtkWidgets
  • GUI layout
  • compositing with volume rendering does not work properly
  • Working group (?)

Infrastructure

• Move to git/gerrit (TBD - can it be used with git-svn or is the suggestion to retire svn?)
• GUI Testing
  • Instrumenting CTK widgets
  • Conversion of tutorials to tests
  • What will this provide that Sikuli does not? Sonia is ready to use Sikuli unless there is a good reason not to.
• Tk/Tcl
  • Removing the last dependencies in core interaction loops - see Slicer4:SliceInteractions
  • Maintain functionality for Editor
• Performance optimization
  • Module for profiling events
• Extensions
  • Support for superbuild
  • Requirements for testing, documentation, tutorials, and continued support from developers
    • How to name different levels of compliance
• Downloads
  • Statistics on packages and on individual extensions
  • Web pages
  • Technologies
• Charts
  • Reference Implementation (Marcus)
• MIDAS
  • sceneviews support
• Interactive CLI modules

Compilation

• Fix numpy builds on win64
  • Need to embed manifests in numpy pyd files
• Fix win64 tcl version
  • currently permission issue with dlls in win64 slicerlib mirror
  • currently using tcl8.4 on win32 and elsewhere but tcl8.5 on win64 (should use the same everywhere if possible)
