Feedback from Ron 08/24/11
- in general: Ron is very pleased with the top-level things
The Text Dilemma
- problem: annotations are obstructing the images: this should NOT be the case
- fonts ugly
- text gets in the way of things you want to see
- different direction needed: show information in left bottom corner
- two kinds of information
- software wants to show information (push)
- user requests information (pull)
- in viewers: minimal information
- in bottom left corner of Slicer GUI: medium details
- somewhere else (in the annotation module): full details
- cdash example: way of not to do it -> important information is covered by annotations
- ohloh example: good example -> first minimal, then under cursor more details when probing
- two kinds of information
Possible Solution
- assign names (F1,F2,F3 for Fiducials, M1,M2,M3 for measurements, R1,R2 for ROI... ) and descriptions
- name appears in viewers
- description in bottom lower left on roll-over in viewers
- in annotation module: full details: Name, description, options
General Changes (Target for RSNA release)
- take everything out which does not work properly (except for critical functionality)
Targeting the Text Dilemma
- name+description in bottom lower left (Steve)
- possible problem: mouse over event on vtk widgets might not be easily realizable. Plan C could be a query mechanism, where the user requests this information through a keystroke or such (if annotation detail is not available we will only show slice information and add annotation detail later).
in viewers only name(Nicole)- one letter naming checked in to svn 17837.
- using name instead of text checked into svn 17889.
Slim down the Annotation Module
get rid of text annotation- get rid of bidimensional annotation
just three annotation types: fiducials, measurements (ruler), ROIs- done in svn 17835
vtkWidget Changes
- ruler: ticks only in 2D, every centimeter, can be turned off (Alex)
- For now, turn off ticks in both 2D and 3D (Alex)
- Later, fix zooming in 2D, only have long (major) ticks at 1cm.
- Later, change to spheres for ticks (at 1cm) in 3D
handles for all annotations zooming behavior: should be like Slicer3(Alex)- ROI needs a name in the future: requires infrastructure change (not for RSNA) (Alex)
- Later: don't turn off ruler visibility when endpoints are outside the viewport
Displayable Manager
- Coordinate issues (Daniel)
- Fiducials and Rulers show up in all slice views when they shouldn't
- Fiducials and Rulers 'jump' on mouse over
Qt GUI Changes
- property dialog re-design
- for RSNA: change default tab in property box: point tab for Fiducial, Ruler; ROI tab for ROI (Daniel)
- sliders in fiducial properties jumps weird: should have dynamic range or 0..20 for the beginning
- size presets: medium is actual size, small and large presets
- property linking between elements of widgets so that the user has to change colors at one location
GUI: Qt Widgets(Daniel) (WIP uploaded to SVN 17896 and 17898)- MRML: DisplayNode changes (Nicole)
- hotspot icons for ruler placement: new icons on wendy's todo list (Wendy)
- second eye should be removed in tree view (Julien)
remove Create Panel(Daniel)replace by toolbar - do we really want to have the toolbar 2x? No!(Daniel)view transform in the toolbar: should be cancel(Daniel)- add a key (maybe ctrl) to have it pause mode (TODO later - now just option to cancel).
- screenshots and sceneviews go into toolbar (Nicole)
take out advanced panel(svn rev. 17835)
MRML Changes
- changes related to linking properties (Jim)
- fiducial list, so that saving many fiducials do not creates so many files (Nicole)
Performance and Stability
- Testing (Nicole)
- add multiple fiducials, ROIs, rulers for timing
- test named py_AnnotationsTestingAddManyFiducials (adds 20 fids) added in svn 17892.
- Volume Rendering multiple renders when fiducials are present (may be inherent in the widgets) (?)
- Fixing why the annotations lead to slowdowns
- Fix random crashes (all)
- Undo/Redo - disable if it does not work (Alex)
