32 // Class Description:
33 //
34 // Calculates the mass of a geometry tree taking into account daughters
35 // up to the depth specified in the G4PhysicalVolumeModel. Culling is
36 // ignored so that all volumes are seen.
37 //
38 // Do not use this for a "parallel world" for which materials are not
39 // defined. Use only for the material world.
40 //
41 // The calculation is quite tricky, since it involves subtracting the
42 // mass of that part of the mother that is occupied by each daughter and
43 // then adding the mass of the daughter, and so on down the heirarchy.
44 //
45 // Usage for a given G4PhysicalVolumeModel* pvModel:
46 // G4PhysicalVolumeMassScene massScene(pvModel);
47 // pvModel->DescribeYourselfTo (massScene);
48 // G4double volume = massScene.GetVolume();
49 // G4double mass = massScene.GetMass();
50 // massScene.Reset();
51 // See, for example, G4ASCIITreeSceneHandler::EndModeling().
