<div dir="ltr">I was unfamiliar until I saw this with ROOT's TGeo classes and their use in defining geometry for multiple (GEANT3, GEANT4, FLUKA) MC engines. Given our interest in supporting both GEANT4 and FLUKA this may be worth looking into. There's a presentation (from 2007) here: <a href="https://indico.cern.ch/event/13356/contribution/35/material/slides/0.ppt">https://indico.cern.ch/event/13356/contribution/35/material/slides/0.ppt</a>.</div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Apr 28, 2015 at 5:46 PM, Zhiwen Zhao <span dir="ltr"><<a href="mailto:zwzhao@jlab.org" target="_blank">zwzhao@jlab.org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi, All<br>

Just FYI<br>
<br>
I notice "DD4hep" which has similar ideas for detector defination<br>
see slides starting from 8 of<br>

On the same site, there are some other interesting packages like<br>
"Usolids","PandoraPFA"<br>
<br>
There are some interesting discussion about software framework here<br>
