Potential segmentation Can we share efforts?
Why not, now sitting together... Cuts costs Improves productivity & quality Example
Allow the use of different geometry packages through the common interface definitions
Motivation
3Atlas Graphics Group Meeting Dec, 1999 [email protected]
Compare the physics capabilities of a Linear Collider Compare the physics capabilities of a Linear Collider
detector with a TESLA detectordetector with a TESLA detector Create a LHC detector description
hep.geometry.Detector detector = new hep.geometry.LHC.Detector(specifications);
Create a TESLA detector description hep.geometry.Detector detector = new
hep.geometry.TESLA.Detector(specifications); Run similar analysis on detector
public void analyze(detector)
Integrate JAS with WIRED geometryIntegrate JAS with WIRED geometry Seamless interaction

hep.XXX Namespace Proposalshep.XXX Namespace Proposals
hep.geometry hep.analysis hep.analysis.histo hep.analysis.random and more
Interface proposals go into Open Source CVS@SLACInterface proposals go into Open Source CVS@SLAC Unlike C++, Java interface feature enforces strict & clean separation Worked upon by participating parties until mutual aggreement reached Javas Portability and Late Linking
eases distributed & heterogenous work on common code bases Code then moves into hep.XXX within CVS Participants may also want to provide a reference implementation
Can serve as simple & straightforward solution Problem specific implementations of the common interface anticipated
