How to display Mu2e geometry

Stntuple/scripts/draw_mu2e_geometry.C allows to display, using ROOT, geometry of the Mu2e detector saved into a GDML file, created by an art job. Class DrawMu2eGeometry has several functions displaying different parts of the Mu2e apparatus. Here is an example of how to draw the solenoids and the detector:

.L Stntuple/scripts/draw_mu2e_geometry.C

dmg = new DrawMu2eGeometry("/home/murat/figures/mu2e/gdml/mu2e_geometry_v6_1_4.gdml")

dmg->HideBuilding(1)

dmg->gm->GetVolume("HallAir")->Draw("ogl")

Other useful drawing functions include:

void DrawCRV();

void DrawCalorimeter();

void DrawCalorimeterDisk();

void DrawExtShielding();

void DrawDetectorSolenoid();

void DrawProductionTarget();

produces the following output:

void DrawStrawTracker();

produces the following output:
