To add a graphics system:
|
|
|
|
1) implement 3 new classes:
|
|
|
|
class G4XXX: public G4VGraphicsSystem
|
|
class G4XXXSceneHandler: public G4VSceneHandler
|
|
class G4XXXViewer: virtual public G4VViewer
|
|
|
|
These should be placed in their own sub-directory under
|
|
visualization, together with a GNUmakefile and a History file.
|
|
Change the library name G4XXX in "name := G4XXX" in GNUmakefile.
|
|
|
|
2) Add to SUBDIRS and SUBLIBS in visualization/GNUmakefile.
|
|
|
|
3) Look at the XXX graphics system teamplate in visualization/XXX and
|
|
use it to build your graphics system.
|
|
|
|
You might also find it useful to look at ASCIITree (and VTree) as
|
|
an example of a minimal graphics system.
|
|
|
|
Look at FukuiRenderer as an example of a system which implements
|
|
AddThis methods for some solids.
|
|
|
|
Look at OpenGL as an example of a system which implements a graphical
|
|
database (display lists) and the machinery to decide when to rebuild.
|
|
(OpenGL is complicated by the proliferation of combinations of:
|
|
|
|
immediate (no display lists) ) ( X-windows
|
|
stored (uses display lists) ) x ( X with motif - interactive
|
|
( Win32
|
|
|
|
(6 combinations) and much use is made of inheritance to avoid code
|
|
duplication.)
|
|
|
|
4) If it requires external libraries, introduce two new environment
|
|
variables G4VIS_BUILD_XXX_DRIVER and G4VIS_USE_XXX and make the
|
|
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
|
|
|
|
In any case, augment the informational printing in G4VisManager.cc.
