Geant4で利用するVisualization Driverを追加する。

Geant4

Geant4のビジュアライゼーションにはOpenGL、DAWN、RayTracerなど様々なものが利用できる。

8.3. The Visualization Drivers

多くのサイトでこのビジュアライゼーションを利用したければ

Idle> /vis/open OGL

とせよと紹介されているのだがそもそもGeantを動かしたときの利用可能リストに載っていない事がある。

これは環境変数が設定されていないのが原因で例えばOpenGLを加えたければ

export G4VIS_USE_OPENGLX=1

を任意の場所で設定してからmakeし直せば動作する。

 

このような環境変数の一覧は、 3. GNUMake System: Makefiles and Environment Variables に載っており。

Visualization specific

The most relevant flags for visualization graphics drivers are just listed here. A description of these variables is given also in section 2. of this User's Guide.

$G4VIS_BUILD_OPENGLX_DRIVER
Specifies to build kernel library for visualization including the OpenGL driver with X11 extension. It requires $OGLHOME set (path to OpenGL installation).
$G4VIS_USE_OPENGLX
Specifies to use OpenGL graphics with X11 extension in the application to be built.
$G4VIS_BUILD_OPENGLXM_DRIVER
Specifies to build kernel library for visualization including the OpenGL driver with XM extension. It requires $OGLHOME set (path to OpenGL installation).
$G4VIS_USE_OPENGLXM
Specifies to use OpenGL graphics with XM extension in the application to be built.
G4VIS_BUILD_OPENGLQT_DRIVER
Specifies to build kernel library for visualization including the OpenGL driver with Qt extension. It requires $QTHOME set to specify the path where Qt libraries and headers are installed.
G4VIS_USE_OPENGLQT
Specifies to use OpenGL graphics with Qt extension in the application to be built.
$G4VIS_BUILD_OI_DRIVER
Specifies to build kernel library for visualization including the OpenInventor driver. It requires $OIHOME set (paths to the OpenInventor installation).
$G4VIS_USE_OI
Specifies to use OpenInventor graphics in the application to be built.
$G4VIS_BUILD_OIX_DRIVER
Specifies to build the driver for the free X11 version of OpenInventor.
$G4VIS_USE_OIX
Specifies to use the free X11 version of OpenInventor.
$G4VIS_BUILD_RAYTRACERX_DRIVER
Specifies to build kernel library for visualization including the Ray-Tracer driver with X11 extension. It requires X11 installed in the system.
$G4VIS_USE_RAYTRACERX
Specifies to use the X11 version of the Ray-Tracer driver.
$G4VIS_BUILD_OIWIN32_DRIVER
Specifies to build the driver for the free X11 version of OpenInventor on Windows systems.
$G4VIS_USE_OIWIN32
Specifies to use the free X11 version of OpenInventor on Windows systems.
$G4VIS_BUILD_DAWN_DRIVER
Specifies to build kernel library for visualization including the driver for DAWN.
$G4VIS_USE_DAWN
Specifies to use DAWN as a possible graphics renderer in the application to be built.
$G4DAWN_HOST_NAME
To specify the hostname for use with the DAWN-network driver.
$G4VIS_NONE
If specified, no visualization drivers will be built or used.
