Download and run

The download area is under the g4view section of the "softinex portal" at :

Here can be found various binary kits.

Apple AppStore

g4view is available on the AppStore since the 10th August 2012. As for ioda, it is an historical date for us. It is probably the first HEP simulation application that can be delivered so easily in this way. Definitely a giant step for us.


The application had been developed with an iPad first generation.

Google play (Android Market)

g4view is available on Google play for devices with at least Android-2.2. Note that the g4view-release.apk is also available from the download area. The first version of this app had been done by using a Samsung Galaxy S first generation.

Cocoa (Mac desktop)

On a Mac, download and unzip the, then click on the g4view icon (or do : open, from a terminal).


At first startup, the program unfolds the brem_SB part of the G4EMLOW data under the document directory of the app. According to the platform, the document directory is :

     UNIX : ~/Documents/g4view
     Windows : C:\Documents and Settings\<user>\Documents\g4view
     Android : /sdcard/Android/data/fr.in2p3.lal.g4view
     iPod/iPhone/iPad : <app dir>/Documents.

On an Android device, we then expect that a "/sdcard" directory exists and is writable. With our "first generation" devices (iPad-1, SGS-1), the initialization of a run is a little bit slow but after the speed of processing of events (that includes tracking, visualization, updating of plots) is suprisingly sufficently good to think to use g4view on tablets as an interactive support for lectures on particle physics detectors.
