33 | // Class description |

34 | // |
---|
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. |
