The LCDD geometry needs to be dumped to plain GDML to be loaded by ROOT.

Before using ROOT, the environment needs to be setup.

export ROOTSYS=/my/root/dir
. $ROOTSYS/bin/

Assuming that there is a file called test.gdml in the current directory, a script similar to the following will load a plain GDML file into ROOT.


This command should display the ROOT OpenGL viewer with the geometry from the test.gdml file.

One can customize this by displaying only a particular volume, specified by name, using the following command:


Note that in the gdml file the volume name has a hexadecimal number appended to it. This should be disregarded when specifying the volume name.
