13 \ingroup Geometry_classes
14 
15  A node represent a volume positioned inside another.They store links to both
16 volumes and to the TGeoMatrix representing the relative positioning. Node are
17 never instantiated directly by users, but created as a result of volume operations.
18 Adding a volume named A with a given user ID inside a volume B will create a node
19 node named A_ID. This will be added to the list of nodes stored by B. Also,
20 when applying a division operation in N slices to a volume A, a list of nodes
21 B_1, B_2, ..., B_N is also created. A node B_i does not represent a unique
22 object in the geometry because its container A might be at its turn positioned
23 as node inside several other volumes. Only when a complete branch of nodes
24 is fully defined up to the top node in the geometry, a given path like:
25 
26  /TOP_1/.../A_3/B_7 will represent an unique object.
27 
28 Its global transformation matrix can be computed as the pile-up of all local
29 transformations in its branch. We will therefore call "logical graph" the
30 hierarchy defined by nodes and volumes. The expansion of the logical graph by
31 all possible paths defines a tree structure where all nodes are unique
32 "touchable" objects. We will call this the "physical tree". Unlike the logical
33 graph, the physical tree can become a huge structure with several milions of nodes
34 in case of complex geometries, therefore it is not always a good idea to keep it
35 transient in memory. Since a the logical and physical structures are correlated, the
36 modeller rather keeps track only of the current branch, updating the current
37 global matrix at each change of the level in geometry. The current physical node
38 is not an object that can be asked for at a given moment, but rather represented
39 by the combination: current node + current global matrix. However, physical nodes
40 have unique ID's that can be retrieved for a given modeler state. These can be
41 fed back to the modeler in order to force a physical node to become current.
42 The advantage of this comes from the fact that all navigation queries check
43 first the current node, therefore knowing the location of a point in the
44 geometry can be saved as a starting state for later use.
45 
46  Nodes can be declared as "overlapping" in case they do overlap with other
47 nodes inside the same container or extrude this container. Non-overlapping
48 nodes can be created with:
49 
50 ~~~ {.cpp}
51  TGeoVolume::AddNode(TGeoVolume *daughter, Int_t copy_No, TGeoMatrix *matr);
52 ~~~
53 
54 The creation of overlapping nodes can be done with a similar prototype:
55 
56 ~~~ {.cpp}
57  TGeoVolume::AddNodeOverlap(same arguments);
58 ~~~
59 
60 When closing the geometry, overlapping nodes perform a check of possible
61 overlaps with their neighbours. These are stored and checked all the time
62 during navigation, therefore navigation is slower when embedding such nodes
63 into geometry.
64 
65  Node have visualization attributes as volume have. When undefined by users,
66 painting a node on a pad will take the corresponding volume attributes.

912 /** \class TGeoIterator
913 \ingroup Geometry_classes
914 A geometry iterator.
915 
916 A geometry iterator that sequentially follows all nodes of the geometrical
917 hierarchy of a volume. The iterator has to be initiated with a top volume
918 pointer:
919 
920 ~~~ {.cpp}
921  TGeoIterator next(myVolume);
922 ~~~
923 
924 One can use the iterator as any other in ROOT:
925 
926 ~~~ {.cpp}
927  TGeoNode *node;
928  while ((node=next())) {
929  ...
930  }
931 ~~~
932 
933 The iterator can perform 2 types of iterations that can be selected via:
934 
935 ~~~ {.cpp}
936  next.SetType(Int_t type);
937 ~~~
938 
939 Here TYPE can be:
940  - 0 (default) - 'first daughter next' behavior
941  - 1 - iteration at the current level only
942 
943 Supposing the tree structure looks like:
944 
945 ~~~ {.cpp}
946 TOP ___ A_1 ___ A1_1 ___ A11_1
947  | | |___ A12_1
948  | |_____A2_1 ___ A21_1
949  | |___ A21_2
950  |___ B_1 ...
951 ~~~
952 
953 The order of iteration for TYPE=0 is: A_1, A1_1, A11_1, A12_1, A2_1, A21_1,
954 A21_2, B_1, ...
955 
956 The order of iteration for TYPE=1 is: A_1, B_1, ...
957 At any moment during iteration, TYPE can be changed. If the last iterated node
958 is for instance A1_1 and the iteration type was 0, one can do:
959 
960 ~~~ {.cpp}
961  next.SetType(1);
962 ~~~
963 
964 The next iterated nodes will be the rest of A daughters: A2,A3,... The iterator
965 will return 0 after finishing all daughters of A.
966 
967 During iteration, the following can be retrieved:
968  - Top volume where iteration started: TGeoIterator::GetTopVolume()
969  - Node at level I in the current branch: TGeoIterator::GetNode(Int_t i)
970  - Iteration type: TGeoIterator::GetType()
971  - Global matrix of the current node with respect to the top volume:
972  TGeoIterator::GetCurrentMatrix()
973 
974 The iterator can be reset by changing (or not) the top volume:
975 
976 ~~~ {.cpp}
977  TGeoIterator::Reset(TGeoVolume *top);
978 ~~~
979 
980 ### Example:
981 
982 We want to find out a volume named "MyVol" in the hierarchy of TOP volume.
983 
984 ~~~ {.cpp}
985  TIter next(TOP);
986  TGeoNode *node;
987  TString name("MyVol");
988  while ((node=next()))
989  if (name == node->GetVolume()->GetName()) return node->GetVolume();
990 ~~~
