32 // Class Description:
33 //
34 // Model for physical volumes. It describes a physical volume and its
35 // daughters to any desired depth. Note: the "requested depth" is
36 // specified in the modeling parameters; enum {UNLIMITED = -1}.
37 //
38 // For access to base class information, e.g., modeling parameters,
39 // use GetModelingParameters() inherited from G4VModel. See Class
40 // Description of the base class G4VModel.
41 //
42 // G4PhysicalVolumeModel assumes the modeling parameters have been set
43 // up with meaningful information - default vis attributes and culling
44 // policy in particular.
45 //
46 // The volumes are unpacked and sent to the scene handler. They are,
47 // in effect, "touchables" as defined by G4TouchableHistory. A
48 // touchable is defined not only by its physical volume name and copy
49 // number but also by its position in the geometry hierarchy.
50 //
51 // It is guaranteed that touchables are presented to the scene handler
52 // in top-down hierarchy order, i.e., ancesters first, mothers before
53 // daughters, so the scene handler can be assured that, if it is
54 // building its own scene graph tree, a mother, if any, will have
55 // already been encountered and there will already be a node in place
56 // on which to hang the current volume. But be aware that the
57 // visibility and culling policy might mean that some touchables are
58 // not passed to the scene handler so the drawn tree might have
59 // missing layers. GetFullPVPath allows you to know the full
60 // hierarchy.
