12/** \class TGeoManager
13\ingroup Geometry_classes
14
15The manager class for any TGeo geometry. Provides user
16interface for geometry creation, navigation, state querying,
17visualization, IO, geometry checking and other utilities.
18
19## General architecture
20
21 The ROOT geometry package is a tool designed for building, browsing,
22tracking and visualizing a detector geometry. The code is independent from
23other external MC for simulation, therefore it does not contain any
24constraints related to physics. However, the package defines a number of
25hooks for tracking, such as media, materials, magnetic field or track state flags,
26in order to allow interfacing to tracking MC's. The final goal is to be
27able to use the same geometry for several purposes, such as tracking,
28reconstruction or visualization, taking advantage of the ROOT features
29related to bookkeeping, I/O, histogramming, browsing and GUI's.
30
31 The geometrical modeler is the most important component of the package and
32it provides answers to the basic questions like "Where am I ?" or "How far
33from the next boundary ?", but also to more complex ones like "How far from
34the closest surface ?" or "Which is the next crossing along a helix ?".
35
36 The architecture of the modeler is a combination between a GEANT-like
37containment scheme and a normal CSG binary tree at the level of shapes. An
38important common feature of all detector geometry descriptions is the
39mother-daughter concept. This is the most natural approach when tracking
40is concerned and imposes a set of constraints to the way geometry is defined.
41Constructive solid geometry composition is used only in order to create more
42complex shapes from an existing set of primitives through boolean operations.
43This feature is not implemented yet but in future full definition of boolean
44expressions will be supported.
45
46 Practically every geometry defined in GEANT style can be mapped by the modeler.
47The basic components used for building the logical hierarchy of the geometry
48are called "volumes" and "nodes". Volumes (sometimes called "solids") are fully
49defined geometrical objects having a given shape and medium and possibly
50containing a list of nodes. Nodes represent just positioned instances of volumes
51inside a container volume and they are not directly defined by user. They are
52automatically created as a result of adding one volume inside other or dividing
53a volume. The geometrical transformation hold by nodes is always defined with
54respect to their mother (relative positioning). Reflection matrices are allowed.
55All volumes have to be fully aware of their containees when the geometry is
56closed. They will build additional structures (voxels) in order to fasten-up
57the search algorithms. Finally, nodes can be regarded as bidirectional links
58between containers and containees objects.
59
60 The structure defined in this way is a graph structure since volumes are
61replicable (same volume can become daughter node of several other volumes),
62every volume becoming a branch in this graph. Any volume in the logical graph
63can become the actual top volume at run time (see TGeoManager::SetTopVolume()).
64All functionalities of the modeler will behave in this case as if only the
65corresponding branch starting from this volume is the registered geometry.
66

68
69 A given volume can be positioned several times in the geometry. A volume
70can be divided according default or user-defined patterns, creating automatically
71the list of division nodes inside. The elementary volumes created during the
72dividing process follow the same scheme as usual volumes, therefore it is possible
73to position further geometrical structures inside or to divide them further more
74(see TGeoVolume::Divide()).
75
76 The primitive shapes supported by the package are basically the GEANT3
77shapes (see class TGeoShape), arbitrary wedges with eight vertices on two parallel
78planes. All basic primitives inherits from class TGeoBBox since the bounding box
79of a solid is essential for the tracking algorithms. They also implement the
80virtual methods defined in the virtual class TGeoShape (point and segment
81classification). User-defined primitives can be directly plugged into the modeler
82provided that they override these methods. Composite shapes will be soon supported
83by the modeler. In order to build a TGeoCompositeShape, one will have to define
84first the primitive components. The object that handle boolean
85operations among components is called TGeoBoolCombinator and it has to be
86constructed providing a string boolean expression between the components names.

95## TGeoManager - the manager class for the geometry package.
96
97 TGeoManager class is embedding all the API needed for building and tracking
98a geometry. It defines a global pointer (gGeoManager) in order to be fully
99accessible from external code. The mechanism of handling multiple geometries
100at the same time will be soon implemented.
101
102 TGeoManager is the owner of all geometry objects defined in a session,
103therefore users must not try to control their deletion. It contains lists of
104media, materials, transformations, shapes and volumes. Logical nodes (positioned
105volumes) are created and destroyed by the TGeoVolume class. Physical
106nodes and their global transformations are subjected to a caching mechanism
107due to the sometimes very large memory requirements of logical graph expansion.
108The caching mechanism is triggered by the total number of physical instances
109of volumes and the cache manager is a client of TGeoManager. The manager class
110also controls the painter client. This is linked with ROOT graphical libraries
111loaded on demand in order to control visualization actions.
112
113## Rules for building a valid geometry
114
115 A given geometry can be built in various ways, but there are mandatory steps
116that have to be followed in order to be validated by the modeler. There are
117general rules : volumes needs media and shapes in order to be created,
118both container and containee volumes must be created before linking them together,
119and the relative transformation matrix must be provided. All branches must
120have an upper link point otherwise they will not be considered as part of the
121geometry. Visibility or tracking properties of volumes can be provided both
122at build time or after geometry is closed, but global visualization settings
123(see TGeoPainter class) should not be provided at build time, otherwise the
124drawing package will be loaded. There is also a list of specific rules :
125positioned daughters should not extrude their mother or intersect with sisters
126unless this is specified (see TGeoVolume::AddNodeOverlap()), the top volume
127(containing all geometry tree) must be specified before closing the geometry
128and must not be positioned - it represents the global reference frame. After
129building the full geometry tree, the geometry must be closed
130(see TGeoManager::CloseGeometry()). Voxelization can be redone per volume after
131this process.
132
133
134 Below is the general scheme of the manager class.
135

137
138## An interactive session
139
140 Provided that a geometry was successfully built and closed (for instance the
141previous example $ROOTSYS/tutorials/geom/rootgeom.C ), the manager class will register
142itself to ROOT and the logical/physical structures will become immediately browsable.
143The ROOT browser will display starting from the geometry folder : the list of
144transformations and media, the top volume and the top logical node. These last
145two can be fully expanded, any intermediate volume/node in the browser being subject
146of direct access context menu operations (right mouse button click). All user
147utilities of classes TGeoManager, TGeoVolume and TGeoNode can be called via the
148context menu.
149
150\image html geom_browser.jpg
151
152### Drawing the geometry
153
154 Any logical volume can be drawn via TGeoVolume::Draw() member function.
155This can be directly accessed from the context menu of the volume object
156directly from the browser.
157 There are several drawing options that can be set with
158TGeoManager::SetVisOption(Int_t opt) method :
159
160#### opt=0
161 only the content of the volume is drawn, N levels down (default N=3).
162 This is the default behavior. The number of levels to be drawn can be changed
163 via TGeoManager::SetVisLevel(Int_t level) method.
164
165\image html geom_frame0.jpg
166
167#### opt=1
168 the final leaves (e.g. daughters with no containment) of the branch
169 starting from volume are drawn down to the current number of levels.
170 WARNING : This mode is memory consuming
171 depending of the size of geometry, so drawing from top level within this mode
172 should be handled with care for expensive geometries. In future there will be
173 a limitation on the maximum number of nodes to be visualized.
174
175\image html geom_frame1.jpg
176
177#### opt=2
178 only the clicked volume is visualized. This is automatically set by
179 TGeoVolume::DrawOnly() method
180
181#### opt=3 - only a given path is visualized. This is automatically set by
182 TGeoVolume::DrawPath(const char *path) method
183
184 The current view can be exploded in cartesian, cylindrical or spherical
185coordinates :
186 TGeoManager::SetExplodedView(Int_t opt). Options may be :
187- 0 - default (no bombing)
188- 1 - cartesian coordinates. The bomb factor on each axis can be set with
189 TGeoManager::SetBombX(Double_t bomb) and corresponding Y and Z.
190- 2 - bomb in cylindrical coordinates. Only the bomb factors on Z and R
191 are considered
192 \image html geom_frameexp.jpg
193
194- 3 - bomb in radial spherical coordinate : TGeoManager::SetBombR()
195
196Volumes themselves support different visualization settings :
197 - TGeoVolume::SetVisibility() : set volume visibility.
198 - TGeoVolume::VisibleDaughters() : set daughters visibility.
199All these actions automatically updates the current view if any.
200
201### Checking the geometry
202
203 Several checking methods are accessible from the volume context menu. They
204generally apply only to the visible parts of the drawn geometry in order to
205ease geometry checking, and their implementation is in the TGeoChecker class
206from the painting package.
207
208#### Checking a given point.
209 Can be called from TGeoManager::CheckPoint(Double_t x, Double_t y, Double_t z).
210This method is drawing the daughters of the volume containing the point one
211level down, printing the path to the deepest physical node holding this point.
212It also computes the closest distance to any boundary. The point will be drawn
213in red.
214
215\image html geom_checkpoint.jpg
216
217#### Shooting random points.
218 Can be called from TGeoVolume::RandomPoints() (context menu function) and
219it will draw this volume with current visualization settings. Random points
220are generated in the bounding box of the top drawn volume. The points are
221classified and drawn with the color of their deepest container. Only points
222in visible nodes will be drawn.
223
224\image html geom_random1.jpg
225
226
227#### Raytracing.
228 Can be called from TGeoVolume::RandomRays() (context menu of volumes) and
229will shoot rays from a given point in the local reference frame with random
230directions. The intersections with displayed nodes will appear as segments
231having the color of the touched node. Drawn geometry will be then made invisible
232in order to enhance rays.
