Represents a single unique copy a of an associated logical volume
in geometrical hierarchy
Represents a division of the associated logical volume
in geometrical hierarchy
Represents a top of a geometrical sub-hierarchy not placed in space
None of its children can coincide with its boundary defined by an associated solid
Two different placements of the same logical volume represent two different geometrical
hierarchies in space
Allows to create a group of volumes bound together without a boundary
All the volumes exits inside the same virtual reference system of the assmebly volume
they belong to
When assembly volume is placed all its children follow the global transformation applied
to their assembly volume
After the assembly volume is placed its children exist as standalone placements in space
independent of each other
Base type for logical surfaces (for the moment only optical)
Abstract element for all solids substitution group
Surface between two physical volumes
Surface between two physical volumes
Definitions of a geometrical hierarchy of a set of volumes
Geometry setup representing the particular geometry hierarchy by refferring to
a given volume which becomes the top level volume
A reference to the previously defined volume
in the structure block chosen by this setup
World volumme can't be an assembly volume
The GDML Schema version consists of 3 digits X.Y.Z
where these mean:
X - major number, increased when major new
features or backward incompatible bug fixes
are added and means the GDML Processor is
allowed to refuse processing of such a
document if this is using the more recent
version of the GDML Schema then GDML Processor
understands
Y - minor number, increased when incremental and
backward compatible changes or improvements
are made into the GDML Schema. GDML Processor
should be able to process such a document
using higher minor version number then that of
the GDML Processor
Z - bugfix revision number, increased when fully
backward compatible changes which resolve a
problem in GDML Schema are applied
