1. WIRED 4 An extensible generic Event Display Mark Donszelmann SLAC, Stanford, U.S.A. CHEP2004, 27 september – 1 october Interlaken, Switzerland.

2. 30 September 2004Mark Donszelmann, CHEP 2004, Interlaken, Switzerland2 WIRED 4 Why version 4 ? Rewrite from scratch Ideas from WIRED 2 and WIRED 3 More maintainable Features Framework for Event Display Implemented as JAS 3 plugin based on FreeHEP HepRep 2 standard graphics format Experiment & Data format independent Easily customizable for your experiment Portable: Windows, MacOsX, Linux … (pure Java) User extensibility

3. 30 September 2004Mark Donszelmann, CHEP 2004, Interlaken, Switzerland3 WIRED 4 Event Display Features Access to HepRep (1 and 2) data Projections Undoable Edits (Actions) Direct and Indirect Interactivity Animated Feedback on User’s actions Enhanced (filtered) picking mode Physics attributes associated with display Detector and Event visibility selection High Quality Vector Graphics Output

4. 30 September 2004Mark Donszelmann, CHEP 2004, Interlaken, Switzerland4 JAS 3 and the WIRED 4 plugin Easy to install and upgrade Uses standard interface and facilities of JAS 3

5. 30 September 2004Mark Donszelmann, CHEP 2004, Interlaken, Switzerland5 WIRED 4 uses HepRep 2 Data representation for Event Displays HepRep 1 consists of information such as tracks and hits adds representations: lines, cylinders, … adds attributes: drawing properties, physics info… XML, CORBA, RMI, etc Added in HepRep 2 data is typed using a hierarchical types geometry and event data can be separated to persist geometry while scanning events

6. 30 September 2004Mark Donszelmann, CHEP 2004, Interlaken, Switzerland6 WIRED 4 Data Access HepRep 2 XML Supported marginally in WIRED 3 HepRep 1 to HepRep 2 converter WIRED 4 can read HepRep 1 data CORBA HepRep Client WIRED 4 can access CORBA servers using a HepEventServer interface

12. 30 September 2004Mark Donszelmann, CHEP 2004, Interlaken, Switzerland12 Graphics Engine Simple and composite projections Normal (Parallel) as well as Special (Fish-Eye) Layered model Hits on top of Tracks, on top of Geometry Used also, without final on-screen drawing: to find bounding box to find nearest object to cursor to find objects within a shape No more intermediate storage straight from HepRep2 data. Fast and Smart iterator with filter for Picking

17. 30 September 2004Mark Donszelmann, CHEP 2004, Interlaken, Switzerland17 Picking Implementation Picking uses graphics engine “redraw” to mark objects which are: nearest to cursor within a shape A filter can be applied to the “redraw” to only pick from: specified layers specified object types A real “redraw” will then “highlight” the picked objects and show them in a table User addition of filters is possible
