SaschaZelzer: /* Wednesday */

=The Common Toolkit Hackfest at the [http://www.dkfz.de/index.html DKFZ] in Heidelberg, Germany hosted by the [http://www.dkfz-heidelberg.de/en/mbi/index.html MBI].=

=Topics=

== (1) Memory Management ==
* Large Image Handling
** streaming
** out of core data management (memory mapped files, etc)
** level of detail
** Google Earth 3D
** caching
* Decide on smartpointers e.g. C++0x/Boost
** Afternoon: check Qt vs C++0x/Boost smartpointers
** Rule: Use Smartpointers of the super-class; if there is no super-class, use the one decided upon in the afternoon...

== (2) Migrate some code to the repository (e.g. Qt widgets) and use it in our respective toolkits ==
Steve: goal to make some progress on consolidating some Qt widgets from our various projects into a repository that we can all contribute to.

[[Projects:ARRA:SlicerAM| Slicer Annotation and Markup project for reporting]]

== (3) DICOM IO layer on top of DCMTK: interpretation of DICOM data ==

* [http://www.atamai.com/cgi-bin/viewvc.cgi/AtamaiVTK/vtkAtamaiIO/?root=cvspriv David Gobbi's CMake/VTK wrappers for DCMTK]
* [http://graphics.tudelft.nl/Projects/DeVIDE Delft project includes DCMTK]

== (4) Interoperability of plugins ==
Steve: Summarize what would it take to make a standard that could handle at least the three following systems:
* [http://www.slicer.org/slicerWiki/index.php/Slicer3:Execution_Model_Documentation Slicer Command Line Execution Model]
* [https://collab01a.scr.siemens.com/xipwiki/index.php/Main_Page XIP / DICOM WG23 Application Hosting]
* [https://collab01a.scr.siemens.com/xipwiki/index.php/Main_Page XIP-Builder / Visual Programming Interface integration]
* [http://www.nitrc.org/projects/jist/ MIPAV/JIST plugins]
*[http://www.na-mic.org/Wiki/index.php/OpenIGTLink OpenIGTLink]
If we can handle those, then that's probably broad enough to cover many common scenarios.

Jc: [[Events:CTK-Hackfest-2010/SlicerPythonQt | PythonQt]] and the [[Events:CTK-Hackfest-2010/SlicerQtPluginArchitecture | Qt based plugin architecture used in SlicerQt]]

Sascha, Olivier: Generic service oriented approach to expose modules for multiple platforms.

== (5) Generic event mechanism (e.g. event bus, translate events into signals) ==

==Monday at DKFZ==
*9:30 Short presentation of agenda
*9:45 – 12:00 Presentation of topic leaders 20 min each including discussion: requirements, existing libraries, … Coffee breaks on demand
*12:00 – 13:00 Lunch
*13:00 – 13:30 General discussion Goal: select three topics to start with in smaller teams
*13:30 – 16:00 More detailed exploration of topics
*16:00 Presentation of first results, planning of further agenda

Hacking...

* [http://github.com/pieper/CTK CTK Git repository]
** Initial layout supports cross-toolkit code in the Libs directory (i.e. qCTKDCMTK that combines Qt with DCMTK)
** We may refactor the directory layout later
** We can consider making an automated [http://blog.fallingsnow.net/2007/08/17/maintaining-an-svn-mirror-directly-from-git/|svn mirror of git]

* Distributing CTK:
** Provide an initial CmakeLists.txt file that exposes a series of options
** Use [[2010_Winter_Project_Week_CMAKE_Build_process| CMake external project (SuperBuild)]]

* DICOM Database schema example
** [http://www.slicer.org/slicerWiki/index.php/DICOM:Database Discussion here].

* Volume rendering [http://dl.dropbox.com/u/1686930/polyp1.nrrd test data]

==Wednesday==

* DICOM interface discussion
** [http://www.slicer.org/slicerWiki/index.php/DICOM:Interface Slicer notes on dicom interface and other server/database interfaces].

* Effort to plug some XIP code into MITK

* Drafting a first generic plugin framework (based on Qt)

* CTK Repository Naming Conventions:
** CTK
*** Libs
**** Core (depends on QtCore, filenames start with ctk)
***** ctkBundleActivator.h
***** cktBundleContext.h
**** DICOM
**** Scripting
***** PythonQt
**** Visualization
***** VTK
***** OpenInventor
**** Widgets
*** Utilities
**** DCMTK
**** ZMQ
*** Testing
*** Examples
*** Documentation

* CTK File Naming Conventions
** ''Considerations:''
*** allow KWStyle regular expressions to identify coding style (style is based on parent class - vtkObjects use vtk style, QObjects use Qt style).
*** name should indicate dependencies - using ctk prefix implies QtCore dependency
