TGeoVolume Class Reference

TGeoVolume, TGeoVolumeMulti, TGeoVolumeAssembly are the volume classes.

Volumes are the basic objects used in building the geometrical hierarchy. They represent unpositioned objects but store all information about the placement of the other volumes they may contain. Therefore a volume can be replicated several times in the geometry. In order to create a volume, one has to put together a shape and a medium which are already defined. Volumes have to be named by users at creation time. Every different name may represent a an unique volume object, but may also represent more general a family (class) of volume objects having the same shape type and medium, but possibly different shape parameters. It is the user's task to provide different names for different volume families in order to avoid ambiguities at tracking time. A generic family rather than a single volume is created only in two cases : when a generic shape is provided to the volume constructor or when a division operation is applied. Each volume in the geometry stores an unique ID corresponding to its family. In order to ease-up their creation, the manager class is providing an API that allows making a shape and a volume in a single step.

Volumes are objects that can be visualized, therefore having visibility, colour, line and fill attributes that can be defined or modified any time after the volume creation. It is advisable however to define these properties just after the first creation of a volume namespace, since in case of volume families any new member created by the modeler inherits these properties.

In order to provide navigation features, volumes have to be able to find the proper container of any point defined in the local reference frame. This can be the volume itself, one of its positioned daughter volumes or none if the point is actually outside. On the other hand, volumes have to provide also other navigation methods such as finding the distances to its shape boundaries or which daughter will be crossed first. The implementation of these features is done at shape level, but the local mother-daughters management is handled by volumes that builds additional optimisation structures upon geometry closure. In order to have navigation features properly working one has to follow the general rules for building a valid geometry (see TGeoManager class).

Now let's make a simple volume representing a copper wire. We suppose that a medium is already created (see TGeoMedium class on how to create media). We will create a TUBE shape for our wire, having Rmin=0cm, Rmax=0.01cm and a half-length dZ=1cm :

TGeoTube *tube = new TGeoTube("wire_tube", 0, 0.01, 1);

One may omit the name for the shape if no retrieving by name is further needed during geometry building. The same shape can be shared by different volumes having different names and materials. Now let's make the volume for our wire. The prototype for volumes constructor looks like :

TGeoVolume::TGeoVolume(const char *name, TGeoShape *shape, TGeoMedium *med)

Since TGeoTube derives from the base shape class, we can provide it to the volume constructor :

TGeoVolume *wire_co = new TGeoVolume("WIRE_CO", tube, ptrCOPPER);

Do not bother to delete neither the media, shapes or volumes that you have created since all will be automatically cleaned on exit by the manager class. If we would have taken a look inside TGeoManager::MakeTube() method, we would have been able to create our wire with a single line :

TGeoVolume *wire_co = gGeoManager->MakeTube("WIRE_CO", ptrCOPPER, 0, 0.01, 1);

The same applies for all primitive shapes, for which there can be found corresponding MakeSHAPE() methods. Their usage is much more convenient unless a shape has to be shared between more volumes. Let's make now an aluminium wire having the same shape, supposing that we have created the copper wire with the line above :

TGeoVolume *wire_al = new TGeoVolume("WIRE_AL", wire_co->GetShape(), ptrAL);

Now that we have learned how to create elementary volumes, let's see how we can create a geometrical hierarchy.

Positioning volumes

When creating a volume one does not specify if this will contain or not other volumes. Adding daughters to a volume implies creating those and adding them one by one to the list of daughters. Since the volume has to know the position of all its daughters, we will have to supply at the same time a geometrical transformation with respect to its local reference frame for each of them. The objects referencing a volume and a transformation are called NODES and their creation is fully handled by the modeler. They represent the link elements in the hierarchy of volumes. Nodes are unique and distinct geometrical objects ONLY from their container point of view. Since volumes can be replicated in the geometry, the same node may be found on different branches.

An important observation is that volume objects are owned by the TGeoManager class. This stores a list of all volumes in the geometry, that is cleaned upon destruction.

Let's consider positioning now our wire in the middle of a gas chamber. We need first to define the gas chamber :

TGeoVolume *chamber = gGeoManager->MakeTube("CHAMBER", ptrGAS, 0, 1, 1);

Now we can put the wire inside :

chamber->AddNode(wire_co, 1);

If we inspect now the chamber volume in a browser, we will notice that it has one daughter. Of course the gas has some container also, but let's keep it like that for the sake of simplicity. The full prototype of AddNode() is :

TGeoVolume::AddNode(TGeoVolume *daughter, Int_t usernumber,
                    TGeoMatrix *matrix=gGeoIdentity)

Since we did not supplied the third argument, the wire will be positioned with an identity transformation inside the chamber. One will notice that the inner radii of the wire and chamber are both zero - therefore, aren't the two volumes overlapping ? The answer is no, the modeler is even relaying on the fact that any daughter is fully contained by its mother. On the other hand, neither of the nodes positioned inside a volume should overlap with each other. We will see that there are allowed some exceptions to those rules.

Overlapping volumes

Positioning volumes that does not overlap their neighbours nor extrude their container is sometimes quite strong constraint. Some parts of the geometry might overlap naturally, e.g. two crossing tubes. The modeller supports such cases only if the overlapping nodes are declared by the user. In order to do that, one should use TGeoVolume::AddNodeOverlap() instead of TGeoVolume::AddNode(). When 2 or more positioned volumes are overlapping, not all of them have to be declared so, but at least one. A point inside an overlapping region equally belongs to all overlapping nodes, but the way these are defined can enforce the modeler to give priorities. The general rule is that the deepest node in the hierarchy containing a point have the highest priority. For the same geometry level, non-overlapping is prioritised over overlapping. In order to illustrate this, we will consider few examples. We will designate non-overlapping nodes as ONLY and the others MANY as in GEANT3, where this concept was introduced:

1. The part of a MANY node B extruding its container A will never be "seen" during navigation, as if B was in fact the result of the intersection of A and B.
2. If we have two nodes A (ONLY) and B (MANY) inside the same container, all points in the overlapping region of A and B will be designated as belonging to A.
3. If A an B in the above case were both MANY, points in the overlapping part will be designated to the one defined first. Both nodes must have the same medium.
4. The slices of a divided MANY will be as well MANY.

One needs to know that navigation inside geometry parts MANY nodes is much slower. Any overlapping part can be defined based on composite shapes - this is always recommended.

Replicating volumes

What can we do if our chamber contains two identical wires instead of one ? What if then we would need 1000 chambers in our detector ? Should we create 2000 wires and 1000 chamber volumes ? No, we will just need to replicate the ones that we have already created.

chamber->AddNode(wire_co, 1, new TGeoTranslation(-0.2,0,0));
chamber->AddNode(wire_co, 2, new TGeoTranslation(0.2,0,0));

The 2 nodes that we have created inside chamber will both point to a wire_co object, but will be completely distinct : WIRE_CO_1 and WIRE_CO_2. We will want now to place symmetrically 1000 chambers on a pad, following a pattern of 20 rows and 50 columns. One way to do this will be to replicate our chamber by positioning it 1000 times in different positions of the pad. Unfortunately, this is far from being the optimal way of doing what we want. Imagine that we would like to find out which of the 1000 chambers is containing a (x,y,z) point defined in the pad reference. You will never have to do that, since the modeller will take care of it for you, but let's guess what it has to do. The most simple algorithm will just loop over all daughters, convert the point from mother to local reference and check if the current chamber contains the point or not. This might be efficient for pads with few chambers, but definitely not for 1000. Fortunately the modeler is smarter than that and create for each volume some optimization structures called voxels (see Voxelization) to minimize the penalty having too many daughters, but if you have 100 pads like this in your geometry you will anyway loose a lot in your tracking performance.

The way out when volumes can be arranged according to simple patterns is the usage of divisions. We will describe them in detail later on. Let's think now at a different situation : instead of 1000 chambers of the same type, we may have several types of chambers. Let's say all chambers are cylindrical and have a wire inside, but their dimensions are different. However, we would like all to be represented by a single volume family, since they have the same properties.

anonymous enum

Enumerator

kOnlyPrepStep

Used to request that the class specific implementation of TObject::Write just prepare the objects to be ready to be written but do not actually write them into the TBuffer. This is just for example by TBufferMerger to request that the TTree inside the file calls TTree::FlushBaskets (outside of the merging lock) and TBufferMerger will later ask for the write (inside the merging lock). To take advantage of this feature the class needs to overload TObject::Write and use this enum value accordingly. (See TTree::Write and TObject::Write) Do not use, this feature will be migrate to the Merge function (See TClass and TTree::Merge)

Member Function Documentation

AbstractMethod()

void TObject::AbstractMethod ( const char * method ) const

inherited

Call this function within a function that you don't want to define as purely virtual, in order not to force all users deriving from that class to implement that maybe (on their side) unused function; but at the same time, emit a run-time warning if they try to call it, telling that it is not implemented in the derived class: action must thus be taken on the user side to override it.

In other word, this method acts as a "runtime purely virtual" warning instead of a "compiler purely virtual" error.

Warning

This interface is a legacy function that is no longer recommended to be used by new development code.

Note

The name "AbstractMethod" does not imply that it's an abstract method in the strict C++ sense.

Definition at line 1149 of file TObject.cxx.

AddNode()

TGeoNode * TGeoVolume::AddNode ( TGeoVolume * vol, Int_t copy_no, TGeoMatrix * mat = nullptr, Option_t * option = "" )

virtual

This is the usual method for adding daughters inside the container volume.

Reimplemented in TGeoVolumeAssembly, and TGeoVolumeMulti.

Definition at line 1095 of file TGeoVolume.cxx.

void TGeoVolume::AddNodeOffset	(	TGeoVolume *	vol,
		Int_t	copy_no,
		Double_t	offset = 0,

CheckedHash()

ULong_t TObject::CheckedHash ( )

inlineinherited

Check and record whether this class has a consistent Hash/RecursiveRemove setup (*) and then return the regular Hash value for this object.

The intent is for this routine to be called instead of directly calling the function Hash during "insert" operations. See TObject::HasInconsistenTObjectHash();

(*) The setup is consistent when all classes in the class hierarchy that overload TObject::Hash do call ROOT::CallRecursiveRemoveIfNeeded in their destructor. i.e. it is safe to call the Hash virtual function during the RecursiveRemove operation.

If STEP<=0, the real STEP will be computed as the full range of IAXIS divided by NDIV. Options (case insensitive):

• N - divide all range in NDIV cells (same effect as STEP<=0) (GSDVN in G3)
• NX - divide range starting with START in NDIV cells (GSDVN2 in G3)
• S - divide all range with given STEP. NDIV is computed and divisions will be centered in full range (same effect as NDIV<=0) (GSDVS, GSDVT in G3)

Note: Since the consistency is only tested for during inserts, this routine will return true for object that have never been inserted whether or not they have a consistent setup. This has no negative side-effect as searching for the object with the right or wrong Hash will always yield a not-found answer (Since anyway no hash can be guaranteed unique, there is always a check)

Write() [2/2]

Int_t TObject::Write ( const char * name = nullptr, Int_t option = 0, Int_t bufsize = 0 ) const

virtualinherited

Write this object to the current directory.

The data structure corresponding to this object is serialized. The corresponding buffer is written to the current directory with an associated key with name "name".

Writing an object to a file involves the following steps:

• Creation of a support TKey object in the current directory. The TKey object creates a TBuffer object.
• The TBuffer object is filled via the class::Streamer function.
• If the file is compressed (default) a second buffer is created to hold the compressed buffer.
• Reservation of the corresponding space in the file by looking in the TFree list of free blocks of the file.
• The buffer is written to the file.

Bufsize can be given to force a given buffer size to write this object. By default, the buffersize will be taken from the average buffer size of all objects written to the current file so far.

If a name is specified, it will be the name of the key. If name is not given, the name of the key will be the name as returned by GetName().

The option can be a combination of: kSingleKey, kOverwrite or kWriteDelete Using the kOverwrite option a previous key with the same name is overwritten. The previous key is deleted before writing the new object. Using the kWriteDelete option a previous key with the same name is deleted only after the new object has been written. This option is safer than kOverwrite but it is slower. NOTE: Neither kOverwrite nor kWriteDelete reduces the size of a TFile– the space is simply freed up to be overwritten; in the case of a TTree, it is more complicated. If one opens a TTree, appends some entries, then writes it out, the behaviour is effectively the same. If, however, one creates a new TTree and writes it out in this way, only the metadata is replaced, effectively making the old data invisible without deleting it. TTree::Delete() can be used to mark all disk space occupied by a TTree as free before overwriting its metadata this way. The kSingleKey option is only used by TCollection::Write() to write a container with a single key instead of each object in the container with its own key.

An object is read from the file into memory via TKey::Read() or via TObject::Read().

The function returns the total number of bytes written to the file. It returns 0 if the object cannot be written.
