Graphics group report for July 2003
   ------------------------------------

 This report will cover the progress in the event displays over several months.


I/ d0ve

 The main item on the to-do list was support for multiple screens for the 
control room display. There has been technical difficulties that are now
overcome and a new version of d0ve is now running online. I haven't seen it 
yet. Filtering by triggers should be available.


II/ d0scan 

  There have been progress on the more technical aspect of getting d0scan to
work with the test releases (GCC). Since we don't have TGS Open Inventor for
that combination of RH release and GCC version, it was decided to give Coin (an
open source implementation) a try. Iguana, the library on which d0scan is
based, has been compiled for GCC. However there are still problems with some 
particular shapes (NURBS) in use in d0scan, there is no immediate solution  
forseen on the Coin side (the claim is that the bug is in the GLU lib). We 
should investigate if we can live without the NURBS.

In addition, new features have been added to d0scan:

  - improved 3D view
      correct problems in MC track display, add unstable particles
      add CFT clusters
      revive MDT hit display

  - improved 2D XY and YZ views
      calorimeter, muon

  - allow to display L1 CAL on the (eta,phi) view for TMBs

  - improved calorimeter lego view  (was on to-do list)
      actual size of cell used
      can view towers and cells (pT or E)
      cell display in ADC counts  depth by depth
      can click on lego and get info about cell/tower

  - improved physics lego view
      automatic Z scaling
      simple cone jets R=0.7

  - general
      bug corrections, fix crashes


 TO DO: 

   - finish the implementation of the XY and RZ views

   - display trigger that passes

   - find a solution for d0scan/Coin

[The list is of course much longer but these are the main points that limits 
 the use of d0scan for analysis and for online]
