2. November 15, 2002 Lassi A. Tuura, Northeastern University http://iguana.cern.ch 2IGUANA v Interactive Graphics for User ANAlysis v Main IGUANA focus: interactive detector and event visualisation r High- performance 2D/3D graphics; r Graphical user interfaces; r Data browsers. v Integration of other tools, components v The goal is to provide common look and feel for the CMS interactive graphical applications v Interactive analysis is not considered a primary goal. It is assumed that this functionality will be provided by other tools (JAS, Hippodraw, Lizard, ROOT, or OpenScientist)

3. November 15, 2002 Lassi A. Tuura, Northeastern University http://iguana.cern.ch 3 Quick Overview v IGUANA: a generic toolkit for user interfaces and visualisation r Builds on existing high-quality libraries (Qt, OpenInventor, Anaphe, …) r Used to implement specific visualisation applications in other projects v Main technical focus: provide a platform that makes it easy to integrate GUIs as a coherent whole, to provide application services and to visualise any application object r Many categories / layers: GUI gadgets & support, application environment, data visualisers, data representation methods, control panels, … r Designed to integrate with and into other applications r Virtually everything is in plug-ins (can still be statically linked) Plug-In Cache Object Factory Object Factory Component Database Plug-In Cache Plug-In Object Factory Attached Unattached

Tuura, Northeastern University http://iguana.cern.ch 10 Present Functionality v Explore and visualise the physical volume tree, with all the usual IGUANA 3D features: view, picking, slices, … v Easy navigation in the volume tree: logical vs. physical, subsets, quick operations for common tasks v Integrated with Martin Liendl’s overlap detection r Find overlaps, show result details in a list r Highlight overlaps in 3D v Geant4 command line v Wizards to guide through program settings v Adding other extensions is trivial (e.g. GUIs like overlap detection) v Volume property window v Tracks and hits

11. November 15, 2002 Lassi A. Tuura, Northeastern University http://iguana.cern.ch 11 Present Functionality… v DCUT, DTREE-like functionality v Volume tree selectors r by material (“show all silicon”) r by sensitive (“show only sensitive detectors”) r for a sub-tree, predefined viewpoints/settings
