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

839/** \class TGeoIterator
840\ingroup Geometry_classes
841A geometry iterator.
842
843A geometry iterator that sequentially follows all nodes of the geometrical
844hierarchy of a volume. The iterator has to be initiated with a top volume
845pointer:
846
847~~~ {.cpp}
848 TGeoIterator next(myVolume);
849~~~
850
851One can use the iterator as any other in ROOT:
852
853~~~ {.cpp}
854 TGeoNode *node;
855 while ((node=next())) {
856 ...
857 }
858~~~
859
860The iterator can perform 2 types of iterations that can be selected via:
861
862~~~ {.cpp}
863 next.SetType(Int_t type);
864~~~
865
866Here TYPE can be:
867 - 0 (default) - 'first daughter next' behavior
868 - 1 - iteration at the current level only
869
870Supposing the tree structure looks like:
871
872~~~ {.cpp}
873TOP ___ A_1 ___ A1_1 ___ A11_1
874 | | |___ A12_1
875 | |_____A2_1 ___ A21_1
876 | |___ A21_2
877 |___ B_1 ...
878~~~
879
880The order of iteration for TYPE=0 is: A_1, A1_1, A11_1, A12_1, A2_1, A21_1,
881A21_2, B_1, ...
882
883The order of iteration for TYPE=1 is: A_1, B_1, ...
884At any moment during iteration, TYPE can be changed. If the last iterated node
885is for instance A1_1 and the iteration type was 0, one can do:
886
887~~~ {.cpp}
888 next.SetType(1);
889~~~
890
891The next iterated nodes will be the rest of A daughters: A2,A3,... The iterator
892will return 0 after finishing all daughters of A.
893
894During iteration, the following can be retrieved:
895 - Top volume where iteration started: TGeoIterator::GetTopVolume()
896 - Node at level I in the current branch: TGeoIterator::GetNode(Int_t i)
897 - Iteration type: TGeoIterator::GetType()
898 - Global matrix of the current node with respect to the top volume:
899 TGeoIterator::GetCurrentMatrix()
900
901The iterator can be reset by changing (or not) the top volume:
902
903~~~ {.cpp}
904 TGeoIterator::Reset(TGeoVolume *top);
905~~~
906
907### Example:
908
909We want to find out a volume named "MyVol" in the hierarchy of TOP volume.
910
911~~~ {.cpp}
912 TIter next(TOP);
913 TGeoNode *node;
914 TString name("MyVol");
915 while ((node=next()))
916 if (name == node->GetVolume()->GetName()) return node->GetVolume();
917~~~
