Geant4 学习心得—AIDA的使用 IV
AIDA(Abstract Interfaces for Data Analysis)主要是提供Hbook，ROOT，或者XML格式输出。在学习的过程中有几种不同的调用方式。
#include "G4RotationMatrix.hh"
class A01DetectorConstruction : public G4VUserDetectorConstruction
{
private:
G4RotationMatrix* armRotation;
}
（2）在DetectorConstruction.cc中定义转动角度，在G4VPlacement中的第一项设置转动。
armRotation = new G4RotationMatrix();
armRotation->rotateY(armAngle);
// second arm
secondArmPhys
= new G4PVPlacement(armRotation,G4ThreeVector(x,0.,z),secondArmLogical,
"secondArmPhys",worldLogical,0,0);
（3）A01中DetectorConstruction.cc的设置磁场转动
// placement of Tube
G4RotationMatrix* fieldRot = new G4RotationMatrix();
fieldRot->rotateX(90.*deg);
new G4PVPlacement(fieldRot,G4ThreeVector(),magneticLogical,
"magneticPhysical",worldLogical,0,0);
