TGeoBBox Class Reference

Box class.

All shape primitives inherit from this, their constructor filling automatically the parameters of the box that bounds the given shape. Defined by 6 parameters :

TGeoBBox()
Default constructor.
Definition TGeoBBox.cxx:164
  • fDX, fDY, fDZ : half lengths on X, Y and Z axis
  • fOrigin[3] : position of box origin

Building boxes

Normally a box has to be built only with 3 parameters: DX,DY,DZ representing the half-lengths on X, Y and Z-axes. In this case, the origin of the box will match the one of its reference frame and the box will range from: -DX to DX on X-axis, from -DY to DY on Y and from -DZ to DZ on Z. On the other hand, any other shape needs to compute and store the parameters of their minimal bounding box. The bounding boxes are essential to optimize navigation algorithms. Therefore all other primitives derive from **TGeoBBox**. Since the minimal bounding box is not necessary centered in the origin, any box allows an origin translation (Ox,Oy,Oz). All primitive constructors automatically compute the bounding box parameters. Users should be aware that building a translated box that will represent a primitive shape by itself would affect any further positioning of other shapes inside. Therefore it is highly recommendable to build non-translated boxes as primitives and translate/rotate their corresponding volumes only during positioning stage.

Creation of boxes

TGeoBBox *box = new TGeoBBox("BOX", 20, 30, 40);
Box class.
Definition TGeoBBox.h:18
void box(Int_t pat, Double_t x1, Double_t y1, Double_t x2, Double_t y2)
Definition fillpatterns.C:1

A volume having a box shape can be built in one step:

TGeoVolume *vbox = gGeoManager->MakeBox("vbox", ptrMed, 20,30,40);
R__EXTERN TGeoManager * gGeoManager
TGeoVolume * MakeBox(const char *name, TGeoMedium *medium, Double_t dx, Double_t dy, Double_t dz)
Make in one step a volume pointing to a box shape with given medium.
TGeoVolume, TGeoVolumeMulti, TGeoVolumeAssembly are the volume classes.
Definition TGeoVolume.h:49

Divisions of boxes

Volumes having box shape can be divided with equal-length slices on X, Y or Z axis. The following options are supported:

  • Dividing the full range of one axis in N slices
    TGeoVolume *divx = vbox->Divide("SLICEX", 1, N);
    #define N
    virtual TGeoVolume * Divide(const char *divname, Int_t iaxis, Int_t ndiv, Double_t start, Double_t step, Int_t numed=0, Option_t *option="")
    Division a la G3.
    here 1 stands for the division axis (1-X, 2-Y, 3-Z)
  • Dividing in a limited range - general case.
    TGeoVolume *divy = vbox->Divide("SLICEY",2,N,start,step);
    • start = starting offset within (-fDY, fDY)
    • step = slicing step

Both cases are supported by all shapes. See also class TGeoShape for utility methods provided by any particular shape.
