TGeoVolumeMulti Class Reference

Volume families.

A volume family is represented by the class TGeoVolumeMulti. It represents a class of volumes having the same shape type and each member will be identified by the same name and volume ID. Any operation applied to a TGeoVolume equally affects all volumes in that family. The creation of a family is generally not a user task, but can be forced in particular cases:

TGeoManager::Volume(const char *vname, const char *shape, Int_t nmed);

where VNAME is the family name, NMED is the medium number and SHAPE is the shape type that can be:

box - for TGeoBBox
trd1 - for TGeoTrd1
trd2 - for TGeoTrd2
trap - for TGeoTrap
gtra - for TGeoGtra
para - for TGeoPara
tube, tubs - for TGeoTube, TGeoTubeSeg
cone, cons - for TGeoCone, TgeoCons
eltu - for TGeoEltu
ctub - for TGeoCtub
pcon - for TGeoPcon
pgon - for TGeoPgon

Volumes are then added to a given family upon adding the generic name as node inside other volume:

TGeoVolume *box_family = gGeoManager->Volume("BOXES", "box", nmed);
gGeoManager->Node("BOXES", Int_t copy_no, "mother_name",
Double_t x, Double_t y, Double_t z, Int_t rot_index,
Bool_t is_only, Double_t *upar, Int_t npar);


BOXES - name of the family of boxes
copy_no - user node number for the created node
mother_name - name of the volume to which we want to add the node
x,y,z - translation components
rot_index - indx of a rotation matrix in the list of matrices
upar - array of actual shape parameters
npar - number of parameters

The parameters order and number are the same as in the corresponding shape constructors.

Another particular case where volume families are used is when we want that a volume positioned inside a container to match one ore more container limits. Suppose we want to position the same box inside 2 different volumes and we want the Z size to match the one of each container:

TGeoVolume *container1 = gGeoManager->MakeBox("C1", imed, 10,10,30);
TGeoVolume *container2 = gGeoManager->MakeBox("C2", imed, 10,10,20);
TGeoVolume *pvol = gGeoManager->MakeBox("PVOL", jmed, 3,3,-1);
container1->AddNode(pvol, 1);
container2->AddNode(pvol, 1);

Note that the third parameter of PVOL is negative, which does not make sense as half-length on Z. This is interpreted as: when positioned, create a box replacing all invalid parameters with the corresponding dimensions of the container. This is also internally handled by the TGeoVolumeMulti class, which does not need to be instantiated by users.

Dividing volumes

Volumes can be divided according a pattern. The most simple division can be done along one axis, that can be: X, Y, Z, Phi, Rxy or Rxyz. Let's take the most simple case: we would like to divide a box in N equal slices along X coordinate, representing a new volume family. Supposing we already have created the initial box, this can be done like:

TGeoVolume *slicex = box->Divide("SLICEX", 1, N);

where SLICE is the name of the new family representing all slices and 1 is the slicing axis. The meaning of the axis index is the following: for all volumes having shapes like box, trd1, trd2, trap, gtra or para - 1,2,3 means X,Y,Z; for tube, tubs, cone, cons - 1 means Rxy, 2 means phi and 3 means Z; for pcon and pgon - 2 means phi and 3 means Z; for spheres 1 means R and 2 means phi. In fact, the division operation has the same effect as positioning volumes in a given order inside the divided container - the advantage being that the navigation in such a structure is much faster. When a volume is divided, a volume family corresponding to the slices is created. In case all slices can be represented by a single shape, only one volume is added to the family and positioned N times inside the divided volume, otherwise, each slice will be represented by a distinct volume in the family. Divisions can be also performed in a given range of one axis. For that, one have to specify also the starting coordinate value and the step:

TGeoVolume *slicex = box->Divide("SLICEX", 1, N, start, step);

A check is always done on the resulting division range : if not fitting into the container limits, an error message is posted. If we will browse the divided volume we will notice that it will contain N nodes starting with index 1 upto N. The first one has the lower X limit at START position, while the last one will have the upper X limit at START+N*STEP. The resulting slices cannot be positioned inside an other volume (they are by default positioned inside the divided one) but can be further divided and may contain other volumes:

TGeoVolume *slicey = slicex->Divide("SLICEY", 2, N1);
slicey->AddNode(other_vol, index, some_matrix);

When doing that, we have to remember that SLICEY represents a family, therefore all members of the family will be divided on Y and the other volume will be added as node inside all. In the example above all the resulting slices had the same shape as the divided volume (box). This is not always the case. For instance, dividing a volume with TUBE shape on PHI axis will create equal slices having TUBESEG shape. Other divisions can also create slices having shapes with different dimensions, e.g. the division of a TRD1 volume on Z. When positioning volumes inside slices, one can do it using the generic volume family (e.g. slicey). This should be done as if the coordinate system of the generic slice was the same as the one of the divided volume. The generic slice in case of PHI division is centered with respect to X axis. If the family contains slices of different sizes, any volume positioned inside should fit into the smallest one. Examples for specific divisions according to shape types can be found inside shape classes.

TGeoVolume::Divide(N, Xmin, Xmax, "X");

The GEANT3 option MANY is supported by TGeoVolumeOverlap class. An overlapping volume is in fact a virtual container that does not represent a physical object. It contains a list of nodes that are not its daughters but that must be checked always before the container itself. This list must be defined by users and it is checked and resolved in a priority order. Note that the feature is non-standard to geometrical modelers and it was introduced just to support conversions of GEANT3 geometries, therefore its extensive usage should be avoided.
