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);

TGeoTube

Cylindrical tube class.

Definition TGeoTube.h:18

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);

TGeoVolume

TGeoVolume, TGeoVolumeMulti, TGeoVolumeAssembly are the volume classes.

Definition TGeoVolume.h:49

TGeoVolume::TGeoVolume

TGeoVolume()

dummy constructor

Definition TGeoVolume.cxx:448

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);

gGeoManager

R__EXTERN TGeoManager * gGeoManager

Definition TGeoManager.h:602

TGeoManager::MakeTube

TGeoVolume * MakeTube(const char *name, TGeoMedium *medium, Double_t rmin, Double_t rmax, Double_t dz)

Make in one step a volume pointing to a tube shape with given medium.

Definition TGeoManager.cxx:2968

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);

TGeoVolume::GetShape

TGeoShape * GetShape() const

Definition TGeoVolume.h:189

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);

TGeoVolume::AddNode

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

Add a TGeoNode to the list of nodes.

Definition TGeoVolume.cxx:932

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)

gGeoIdentity

R__EXTERN TGeoIdentity * gGeoIdentity

Definition TGeoMatrix.h:478

TGeoMatrix

Geometrical transformation package.

Definition TGeoMatrix.h:41

int

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:

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.
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.
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.
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));

TGeoTranslation

Class describing translations.

Definition TGeoMatrix.h:122

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.

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)
