---|
| 122 | |
---|
| 123 | Listed here is some relevant information on developments included in this |
---|
| 124 | release, some of which may require migrations (mainly for users of advanced |
---|
| 125 | Geant4 features) in order to upgrade from release 9.1 to release 9.2. |
---|
| 126 | Note that for all users a full re-installation of libraries (or a full |
---|
| 127 | recompilation) and a recompilation of user applications is required. |

| 232 | is now part of Geant4. Such a description can be used as an alternative |
---|
| 233 | to GDML or other persistency techniques, and is provided with a corresponding set |
---|
| 234 | of UI commands.</LI> |
---|
| 235 | <LI>GDML: the GDML plugin module adds export capabilities, |
---|
| 236 | and thus replaces completely the external GDML module required in older versions |
---|
| 237 | of Geant4. The GDML schema has been upgraded to support missing |

| 244 | <LI>The layout of the Qt interface, <TT>G4UIQt</TT>, which was introduced in |

| 245 | release 9.1 as a <I>Beta</I> release, has been improved. It now supports both common |
---|
| 246 | versions of Qt: Qt3 and Qt4, and provides all the functionality of previous |
---|
| 247 | graphical user interfaces (such as Xm, Win32...). Also implemented a help |
---|
| 248 | widget to easily browse the entire Geant4 command system.</LI> |
---|
| 249 | <LI>Major Improvements have been made to the Qt visualization driver. This |
---|
| 250 | driver now includes all of the capabilties of the other OpenGL drivers, |
---|
| 251 | but adds additional controls to rotate, translate, zoom, to export to many |
---|
| 252 | graphics formats (jpeg, eps, ps, pdf) and to easily create visualization |
---|
| 253 | movies.</LI> |
---|
| 254 | <LI>The 2D drawing capability has been extended; added in previous release just |
---|
| 255 | for <TT>G4Text</TT>, it now also include <TT>G4Circle, |
---|
| 256 | G4Polyhedron, G4Polyline, G4Polymarker</TT> and <TT>G4Square</TT>. |
---|
| 257 | It allows placement in the 2D "screen window". Useful for tasks such as |

---|
| 310 | advanced description of LPM effect; it can be applied for electrons and |
---|
| 311 | positrons with <TT>E > 1 GeV</TT> and provides gamma spectra which agree |
---|
| 312 | well with thin-target experimental data.<BR> |
---|
| 313 | The density suppression effect in the old <TT>G4eBremsstrahlungModel</TT> |
---|
| 314 | has been reviewed and improved.</LI> |
---|
| 315 | <LI>The <TT>G4IonFluctuations</TT> model has been updated: at high energy |
---|
| 316 | it uses <TT>G4UniversalFluctuation</TT>, which provides Landau tail of |
---|
| 317 | fluctuations. |
---|
| 318 | At low energies it uses Gaussian distribution based on experimental data.</LI> |
---|
| 319 | <LI>The <TT>G4Cerenkov</TT> process now enforces a step limitation at the |
---|
| 320 | Cerenkov threshold and a new user defined step limitation provides for |
---|
| 321 | smoother X-ray emission.</LI> |
---|
| 322 | <LI>A new <TT>G4EmSaturation</TT> class is introduced for sampling of Birks |
---|
| 323 | saturation.</LI> |
---|
| 324 | <LI>A new <TT>G4ElectronIonPair</TT> helper class based on the ICRU'31 report has |
---|
| 325 | been added; it can be used for sampling electron/ion pairs in sensitive |
---|
| 326 | detectors.</LI> |
---|
| 327 | <LI>A new <TT>G4EmConfigurator</TT> class can be used for configuration of |
---|
| 328 | models in physics lists.</LI> |
