Geant4 includes many cross-platform file-based visualization drivers, together with the lightweight inexlib library for basic analysis. Geant4 does not require any additional software over and above that listed in Section 1.2 to build and install these components.

However, you may wish to install the third-party software suggested below to make use of these components when running your Geant4 application. We again emphasize that you do not need these packages to build and install Geant4. Also note that Geant4 cannot provide support on installing or using these packages. Any issues here should be reported to the developers of the package.

For more details on Geant4's visualization and analysis components, you should consult the relevant sections in the Geant4 User's Guide for Application Developers.
