Graphics Support And Visualization

Graphics Support And Visualization

• J Kallenbach

2
Project Drivers Scope

• Help (consulting/coding) on graphics applications
  as requested
• Help with generation of publication pictures
  (Public Affairs)
• Revival of 3D applications and outreach (also w/
  Public Affairs)

Project Deliverables Status

• Full-feature event display (FLARE)
• Prototype has been shown to good reviews
• Code (ROOT scripts and support files) in CVS
• Uses ROOT on Linux requires v4_02 or later
• Pictures will be of use to Public Affairs
  (splashy)
• Will also show nicely in 3D
• Waiting to see if FLARE has some life
• Port of NTF visualization code and X Windows
  framework from SGI to Linux
• Port looked like 80 hr job at outset
• Port from SGI GLForms with cc to Linux xforms
  with gcc was fast (compiling)
• Major snag encountered on first Linux link
• Move off of IRIX GL will take some time may
  require a nearly complete rewrite of a few key
  files

Project Deliverables Status - 2

• Public Affairs pics
• We are able to make single pictures
• Still working on cookbook (getting close though)
• CDF, D0 involved
• FLARE output is usable
• MINOS probably wont be part of it
• 3D
• Last attempt became seriously hindered by Linux
  upgrade.
• Currently investigating migration to setup in use
  at UIUC and other sites
• Based on commodity hardware and software (no
  proprietary software or video cards)
• Will become part of a 20-facility GeoWall
  consortium - http//geowall.geo.lsa.umich.edu/
• Evaluation of complete system in progress
• ROOT pictures (or any other GL application)
  should display as is

Effort Profile

• FLARE
• 20, with Adam Para ongoing for 8 months or
  so. Will depend on experiments status. Up to
  25 after 6/1 (NTF delivery, semester).
• NTF
• 40, hopefully completed by 06/01/05
• Post-delivery support to Tom Kroc NTF group
  (up to 1 day/week)
• Public Affairs
• 10, ongoing consulting, trouble-shooting,
  FLARE pics, looking around for other sources of
  images besides CDF, D0, FLARE
• 3D
• 20, ongoing, 45 after 6/1
• Post-delivery effort will include writing of
  unattended demos (movies), getting on tour
  schedule, docent training, conversion of existing
  ROOT displays, public affairs involvement, etc.
• Vacation
• 20 until 05/31

Risks

• NTF
• This may result in some lost time. It is
  slightly unclear whether the task at hand can
  actually be completed in a reasonable amount of
  time. It may turn out to be better to pay SGI
  the 1000/yr.
• 3D
• I THINK most of the risk has been removed this
  time around
• The procedure is now documented, supported by a
  lot of people
• The use of OpenGL and commodity HW instead of
  Inventor and video board make this attempt
  low-risk. Upgrade purchases can be re-used in
  case of discontinuation.
• About 1000 at stake
