Detailed Description

Class to group some Geant4 volumes and place them all at once with a given transformation matrix.

This is similar to the G4VolumeAssembly but is much simpler and with less options

add() [1/2]

void add ( const GeoVXDAssembly &  assembly, const G4Transform3D &  transform = G4Transform3D()  )

inline

Add a assembly to the assembly.

Parameters

assembly	assembly to be added
transform	Transformation to be applied to the volume

Definition at line 53 of file GeoVXDAssembly.h.

      {
        for (const Placement& p : assembly.m_volumes) {
          m_volumes.push_back(std::make_pair(p.first, transform * p.second));
        }
      }

add() [2/2]

void add ( G4LogicalVolume *  volume, const G4Transform3D &  transform = G4Transform3D()  )

inline

Add a volume to the assembly.

Parameters

volume	Volume to be added
transform	Transformation to be applied to the volume

Definition at line 44 of file GeoVXDAssembly.h.

place()

void place	(	G4LogicalVolume *	mother,
		const G4Transform3D &	transform
	)

Place all the volumes already added to the assembly in the given mother.

Parameters

mother	Pointer to the volume everything should be placed in
transform	Transformation to apply to all volumes when placing them

    {
      G4ReflectionFactory& reflection = *G4ReflectionFactory::Instance();
      int numberOfDaughters = mother->GetNoDaughters();
      for (Placement& p : m_volumes) {
        reflection.Place(transform * p.second, p.first->GetName(), p.first,
                         mother, false, ++numberOfDaughters, false);
