|

| 35 | // Concrete Visualization Manager that implements the virtual
|
|---|
| 36 | // functions RegisterGraphicsSystems and RegisterModelFactories. This
|
|---|
| 37 | // is executed when you Initialise() or Initialize() the vis manager.
|
|---|
| 38 | // It exploits C-pre-processor variables G4VIS_USE_DAWN, etc., which
|
|---|
| 39 | // are set by the GNUmakefiles if environment variables of the same
|
|---|
| 40 | // name are set.
|
|---|
| 41 | //
|
|---|
| 42 | // Include this file and write code to instantiate G4VisExecutive just
|
|---|
| 43 | // once as beginning of operations. Before you compile, set
|
|---|
| 44 | // appropriate environment variables. If you change your environment
|
|---|
| 45 | // you must force recompilation (the make files will not detect the
|
|---|
| 46 | // need to do this). Typically, your main program file will contain:
|
|---|
| 47 | //
|
|---|
| 48 | // #ifdef G4VIS_USE
|
|---|
| 49 | // #include "G4VisExecutive.hh"
|
|---|
| 50 | // #endif
|
|---|
| 51 | // ...
|
|---|
| 52 | // int main() {
|
|---|
| 53 | // ...
|
|---|
| 54 | // #ifdef G4VIS_USE
|
|---|
| 55 | // // Instantiate and initialise Visualization Manager.
|
|---|
| 56 | // G4VisManager* visManager = new G4VisExecutive;
|
|---|
| 57 | // // visManager -> SetVerboseLevel (verbosityString);
|
|---|
| 58 | // // visManager -> RegisterGraphicsSystem (new G4XXX);
|
|---|
| 59 | // visManager -> Initialize ();
|
|---|
| 60 | // #endif
|
|---|
| 61 | // ...
|
|---|
| 62 | // #ifdef G4VIS_USE
|
|---|
| 63 | // G4cout << "Deleting vis manager..." << G4endl;
|
|---|
| 64 | // delete visManager;
|
|---|
| 65 | // G4cout << "Vis manager deleted." << G4endl;
|
|---|
| 66 | // #endif
|
|---|
| 67 | //
|
|---|
| 68 | // The implementation is included as an .icc file because - for those
|
|---|
| 69 | // graphics systems that need external libraries - only those
|
|---|
| 70 | // systems that have been selected by the flags may be instantiated
|
|---|
| 71 | // without causing unresolved references (only the user knows which
|
|---|
| 72 | // libraries are available on his/her computer). It also ensures
|
|---|
| 73 | // that libraries can be linked in the right order, without circular
|
|---|
| 74 | // dependencies. (Note that some graphics systems, notable those
|
|---|
| 75 | // that write files for off-line viewing, do not suffer these
|
|---|
| 76 | // restrictions and are always registered.) Additional graphics
|
|---|
| 77 | // systems, XXX say, can be individually registered before
|
|---|
| 78 | // invocation of Initialise() with RegisterGraphicsSystem(new XXX).
|
|---|
| 79 | //
|
|---|
| 80 | // Alternatively, you can implement an empty function here and just
|
|---|
| 81 | // register the systems you want in your main(), e.g.:
|
|---|
| 82 | // G4VisManager* visManager = new G4VisExecutive;
|
|---|
| 83 | // visManager -> RegisterGraphicsSystem (new MyGraphicsSystem);
|
|---|
| 84 | //
|
|---|
| 85 | // See class description of G4VisManager for more details.
