// Class Description:
|
|
//
|
|
// Calculates the mass of a geometry tree taking into account daughters
|
|
// up to the depth specified in the G4PhysicalVolumeModel. Culling is
|
|
// ignored so that all volumes are seen.
|
|
//
|
|
// The calculation is quite tricky, since it involves subtracting the
|
|
// mass of that part of the mother that is occupied by each daughter and
|
|
// then adding the mass of the daughter, and so on down the heirarchy.
|
|
//
|
|
// Usage for a given G4PhysicalVolumeModel* pvModel:
|
|
// G4PhysicalVolumeMassScene massScene;
|
|
// massScene.EstablishSpecials (*pvModel);
|
|
// pvModel->DescribeYourselfTo (massScene);
|
|
// G4double volume = massScene.GetVolume();
|
|
// G4double mass = massScene.GetMass();
|
|
// massScene.Reset();
|
|
// See, for example, G4ASCIITreeSceneHandler::EndModeling().
