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 :

  • 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 build only with 3 parameters : dx, dy, dz representing the half lengths on X, Y and Z axis. In this case, the origin of the box will match the one of its reference frame. The translation of the origin is used only by the constructors of all other shapes in order to define their own bounding boxes. Users should be aware that building a translated box that will represent a physical shape by itself will affect any further positioning of other shapes inside. Therefore in order to build a positioned box one should follow the recipe described in class TGeoNode.

Creation of boxes

{
TCanvas *c = new TCanvas("c", "c",0,0,600,600);
new TGeoManager("box", "poza1");
TGeoMaterial *mat = new TGeoMaterial("Al", 26.98,13,2.7);
TGeoMedium *med = new TGeoMedium("MED",1,mat);
TGeoVolume *top = gGeoManager->MakeBox("TOP",med,100,100,100);
TGeoVolume *vol = gGeoManager->MakeBox("BOX",med, 20,30,40);
vol->SetLineWidth(2);
top->AddNode(vol,1);
top->Draw();
TView *view = gPad->GetView();
view->ShowAxis();
}
  • A volume having a box shape can be built in one step: TGeoVolume *vbox = gGeoManager->MakeBox("vbox", ptrMed, 20,30,40);

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);
    • here 1 stands for the division axis (1-X, 2-Y, 3-Z)
{
TCanvas *c = new TCanvas("c", "c",0,0,600,600);
new TGeoManager("box", "poza1");
TGeoMaterial *mat = new TGeoMaterial("Al", 26.98,13,2.7);
TGeoMedium *med = new TGeoMedium("MED",1,mat);
TGeoVolume *top = gGeoManager->MakeBox("TOP",med,100,100,100);
TGeoVolume *vol = gGeoManager->MakeBox("BOX",med, 20,30,40);
vol->SetLineWidth(2);
top->AddNode(vol,1);
TGeoVolume *divx = vol->Divide("SLICE",1,8,0,0);
top->Draw();
TView *view = gPad->GetView();
view->ShowAxis();
}
  • 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
{
TCanvas *c = new TCanvas("c", "c",0,0,600,600);
new TGeoManager("box", "poza1");
TGeoMaterial *mat = new TGeoMaterial("Al", 26.98,13,2.7);
TGeoMedium *med = new TGeoMedium("MED",1,mat);
TGeoVolume *top = gGeoManager->MakeBox("TOP",med,100,100,100);
TGeoVolume *vol = gGeoManager->MakeBox("BOX",med, 20,30,40);
vol->SetLineWidth(2);
top->AddNode(vol,1);
TGeoVolume *divx = vol->Divide("SLICE",2,8,2,3);
top->Draw();
TView *view = gPad->GetView();
view->ShowAxis();
}

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