Example of use GDML extension and associated reader
|
|
-----------------------------------------------------------
|
|
|
|
In this directory you can find an example showing how to extend the GDML
|
|
schema and plug-in a custom reader to the system for handling the extension.
|
|
For more information, please, refer to the GDML Documentation.
|
|
|
|
The Geometry is a Simple Box to which it is assigned a color as
|
|
visualization attribute.
|
|
The entity "color" is defined as part of the "extension" tag and properly
|
|
implemented in the GDML schema extension placed inside the directory
|
|
SimpleExtensionSchema.
|
|
The GDML file implenting the geometry with colors extension is
|
|
color_extension.gdml, in which the standard "gdml" tag has been replaced
|
|
by the "gdml_simple_extension" tag, with relative location for the new schema.
|
|
The GDML file is automatically loaded by the program.
|
|
It is also possible to use UI commands or macros as arguments to read any
|
|
standard GDML file.
|
|
|
|
HOW TO BUILD THE EXAMPLE ?
|
|
|
|
- You need to have built the persistency/gdml plugin module along with the
|
|
Geant4 libraries, by having set the G4LIB_BUILD_GDML variable in your
|
|
environment.
|
|
It is also required to specify the path where the XercesC XML parser
|
|
package is installed in your system, through the variable XERCESCROOT.
|
|
|
|
- Compile and link to generate the executable:
|
|
% gmake
|
|
|
|
- Execute the application:
|
|
% read_ext [macro-file.mac]
|
