To add a graphics system implement 3 new classes:
|
|
|
|
class G4XXX: public G4VGraphicsSystem
|
|
class G4XXXSceneHandler: public G4VSceneHandler
|
|
class G4XXXViewer: virtual public G4VViewer
|
|
|
|
Introduce two new environment variables G4VIS_BUILD_XXX_DRIVER and GG4VIS_USE_XXX and make the attached modifications to:
|
|
|
|
source/visualization/management/include/MyVisManager.cc
|
|
(similarly all examples vis managers)
|
|
source/visualization/management/src/G4VisManager.cc
|
|
config/G4VIS_BUILD.gmk
|
|
config/G4VIS_USE.gmk
