// Class description
|
|
//
|
|
// Concrete Visualization Manager that implements the virtual function
|
|
// RegisterGraphicsSystems. This is executed when you Initialise()
|
|
// or Initialize() the vis manager. It exploits C-pre-processor
|
|
// variables G4VIS_USE_DAWN, etc., which are set by the GNUmakefiles
|
|
// if environment variables of the same name are set.
|
|
//
|
|
// Include this file and write code to instantiate G4VisExecutive just
|
|
// once as beginning of operations. Before you compile, set
|
|
// appropriate environment variables. If you change your
|
|
// environment you must force recompilation (the make files will not
|
|
// detect the need to do this). Typically, your main program file
|
|
// will contain:
|
|
//
|
|
// #ifdef G4VIS_USE
|
|
// #include "G4VisExecutive.hh"
|
|
// #endif
|
|
// ...
|
|
// int main() {
|
|
// ...
|
|
// #ifdef G4VIS_USE
|
|
// // Instantiate and initialise Visualization Manager.
|
|
// G4VisManager* visManager = new G4VisExecutive;
|
|
// // visManager -> SetVerboseLevel (verbosityString);
|
|
// // visManager -> RegisterGraphicsSystem (new G4XXX);
|
|
// visManager -> Initialize ();
|
|
// #endif
|
|
// ...
|
|
// #ifdef G4VIS_USE
|
|
// G4cout << "Deleting vis manager..." << G4endl;
|
|
// delete visManager;
|
|
// G4cout << "Vis manager deleted." << G4endl;
|
|
// #endif
|
|
//
|
|
// The implementation is included as an .icc file because - for those
|
|
// graphics systems that need external libraries - only those
|
|
// systems that have been selected by the flags may be instantiated
|
|
// without causing unresolved references (only the user knows which
|
|
// libraries are available on his/her computer). It also ensures
|
|
// that libraries can be linked in the right order, without circular
|
|
// dependencies. (Note that some graphics systems, notable those
|
|
// that write files for off-line viewing, do not suffer these
|
|
// restrictions and are always registered.) Additional graphics
|
|
// systems, XXX say, can be individually registered before
|
|
// invocation of Initialise() with RegisterGraphicsSystem(new XXX).
|
|
//
|
|
// Alternatively, you can implement an empty function here and just
|
|
// register the systems you want in your main(), e.g.:
|
|
// G4VisManager* visManager = new G4VisExecutive;
|
|
// visManager -> RegisterGraphicsSystem (new MyGraphicsSystem);
|
|
//
|
|
// See class description of G4VisManager for more details.
