Example of definition of a GDML extension with associated reader and writer
|
|
---------------------------------------------------------------------------
|
|
|
|
In this directory you can find an example showing how to extend the GDML
|
|
schema and plug-in a custom reader and writer 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 module by having
|
|
set the -DGEANT4_USE_GDML=ON flag during the CMAKE configuration step,
|
|
as well as the -DXERCESC_ROOT_DIR=<path_to_xercesc> flag pointing to
|
|
the path where the XercesC XML parser package is installed in your system.
|
|
|
|
- Compile and link to generate the executable (in your CMAKE build directory):
|
|
% make
|
|
|
|
- Execute the application for reading and visualizing the setup:
|
|
% gdml_ext read_ext.mac
|
|
|
|
- Execute the application for also writing the setup:
|
|
% gdml_ext [write_ext.mac]
