|
This example illustrates how to create a "vis action".
|
|
|
|
The idea is that you register a vis action with the vis manager and
|
|
activate it by a command /vis/scene/add/userAction. In this case, it
|
|
draws a simple logo.
|
|
|
|
1) UVA_VisAction.cc defines a G4VUserVisAction and implements a Draw
|
|
method.
|
|
|
|
2) In the main () program (see userVisAction.cc), UVA_VisAction is instantiated and
|
|
its pointer registerd with the visualization manager. You may
|
|
optionally specify an extent at this point to assist the viewers to
|
|
locate the objects.
|
|
|
|
3) To visualise, use the usual Geant4 vis commands to create a view
|
|
and scene, then add the vis action to the scene with
|
|
\verbatim
|
|
/vis/scene/add/userAction
|
|
\endverbatim
|
|
see vis.mac.
|
|
|
|
Note: The system needs an "extent" in order to point the virtual
|
|
camera and adjust its field of view, etc. This defines the "standard
|
|
view". You may zoom, etc., from this standard view.
