TGeoManager Class Reference

The manager class for any TGeo geometry.

Provides user interface for geometry creation, navigation, state querying, visualization, IO, geometry checking and other utilities.

General architecture

The ROOT geometry package is a tool designed for building, browsing, tracking and visualizing a detector geometry. The code is independent from other external MC for simulation, therefore it does not contain any constraints related to physics. However, the package defines a number of hooks for tracking, such as media, materials, magnetic field or track state flags, in order to allow interfacing to tracking MC's. The final goal is to be able to use the same geometry for several purposes, such as tracking, reconstruction or visualization, taking advantage of the ROOT features related to bookkeeping, I/O, histogramming, browsing and GUI's.

The geometrical modeler is the most important component of the package and it provides answers to the basic questions like "Where am I ?" or "How far from the next boundary ?", but also to more complex ones like "How far from the closest surface ?" or "Which is the next crossing along a helix ?".

The architecture of the modeler is a combination between a GEANT-like containment scheme and a normal CSG binary tree at the level of shapes. An important common feature of all detector geometry descriptions is the mother-daughter concept. This is the most natural approach when tracking is concerned and imposes a set of constraints to the way geometry is defined. Constructive solid geometry composition is used only in order to create more complex shapes from an existing set of primitives through boolean operations. This feature is not implemented yet but in future full definition of boolean expressions will be supported.

Practically every geometry defined in GEANT style can be mapped by the modeler. The basic components used for building the logical hierarchy of the geometry are called "volumes" and "nodes". Volumes (sometimes called "solids") are fully defined geometrical objects having a given shape and medium and possibly containing a list of nodes. Nodes represent just positioned instances of volumes inside a container volume and they are not directly defined by user. They are automatically created as a result of adding one volume inside other or dividing a volume. The geometrical transformation hold by nodes is always defined with respect to their mother (relative positioning). Reflection matrices are allowed. All volumes have to be fully aware of their containees when the geometry is closed. They will build additional structures (voxels) in order to fasten-up the search algorithms. Finally, nodes can be regarded as bidirectional links between containers and containees objects.

The structure defined in this way is a graph structure since volumes are replicable (same volume can become daughter node of several other volumes), every volume becoming a branch in this graph. Any volume in the logical graph can become the actual top volume at run time (see TGeoManager::SetTopVolume()). All functionalities of the modeler will behave in this case as if only the corresponding branch starting from this volume is the registered geometry.

A given volume can be positioned several times in the geometry. A volume can be divided according default or user-defined patterns, creating automatically the list of division nodes inside. The elementary volumes created during the dividing process follow the same scheme as usual volumes, therefore it is possible to position further geometrical structures inside or to divide them further more (see TGeoVolume::Divide()).

The primitive shapes supported by the package are basically the GEANT3 shapes (see class TGeoShape), arbitrary wedges with eight vertices on two parallel planes. All basic primitives inherits from class TGeoBBox since the bounding box of a solid is essential for the tracking algorithms. They also implement the virtual methods defined in the virtual class TGeoShape (point and segment classification). User-defined primitives can be directly plugged into the modeler provided that they override these methods. Composite shapes will be soon supported by the modeler. In order to build a TGeoCompositeShape, one will have to define first the primitive components. The object that handle boolean operations among components is called TGeoBoolCombinator and it has to be constructed providing a string boolean expression between the components names.

TGeoManager - the manager class for the geometry package.

TGeoManager class is embedding all the API needed for building and tracking a geometry. It defines a global pointer (gGeoManager) in order to be fully accessible from external code. The mechanism of handling multiple geometries at the same time will be soon implemented.

TGeoManager is the owner of all geometry objects defined in a session, therefore users must not try to control their deletion. It contains lists of media, materials, transformations, shapes and volumes. Logical nodes (positioned volumes) are created and destroyed by the TGeoVolume class. Physical nodes and their global transformations are subjected to a caching mechanism due to the sometimes very large memory requirements of logical graph expansion. The caching mechanism is triggered by the total number of physical instances of volumes and the cache manager is a client of TGeoManager. The manager class also controls the painter client. This is linked with ROOT graphical libraries loaded on demand in order to control visualization actions.

Rules for building a valid geometry

A given geometry can be built in various ways, but there are mandatory steps that have to be followed in order to be validated by the modeler. There are general rules : volumes needs media and shapes in order to be created, both container and containee volumes must be created before linking them together, and the relative transformation matrix must be provided. All branches must have an upper link point otherwise they will not be considered as part of the geometry. Visibility or tracking properties of volumes can be provided both at build time or after geometry is closed, but global visualization settings (see TGeoPainter class) should not be provided at build time, otherwise the drawing package will be loaded. There is also a list of specific rules : positioned daughters should not extrude their mother or intersect with sisters unless this is specified (see TGeoVolume::AddNodeOverlap()), the top volume (containing all geometry tree) must be specified before closing the geometry and must not be positioned - it represents the global reference frame. After building the full geometry tree, the geometry must be closed (see TGeoManager::CloseGeometry()). Voxelization can be redone per volume after this process.

Below is the general scheme of the manager class.

An interactive session

Provided that a geometry was successfully built and closed (for instance the previous example $ROOTSYS/tutorials/geom/rootgeom.C ), the manager class will register itself to ROOT and the logical/physical structures will become immediately browsable. The ROOT browser will display starting from the geometry folder : the list of transformations and media, the top volume and the top logical node. These last two can be fully expanded, any intermediate volume/node in the browser being subject of direct access context menu operations (right mouse button click). All user utilities of classes TGeoManager, TGeoVolume and TGeoNode can be called via the context menu.

Drawing the geometry

Any logical volume can be drawn via TGeoVolume::Draw() member function. This can be directly accessed from the context menu of the volume object directly from the browser. There are several drawing options that can be set with TGeoManager::SetVisOption(Int_t opt) method :

opt=0

only the content of the volume is drawn, N levels down (default N=3). This is the default behavior. The number of levels to be drawn can be changed via TGeoManager::SetVisLevel(Int_t level) method.

geom_frame0.jpg

opt=1

the final leaves (e.g. daughters with no containment) of the branch starting from volume are drawn down to the current number of levels. WARNING : This mode is memory consuming depending of the size of geometry, so drawing from top level within this mode should be handled with care for expensive geometries. In future there will be a limitation on the maximum number of nodes to be visualized.

geom_frame1.jpg

opt=2

only the clicked volume is visualized. This is automatically set by TGeoVolume::DrawOnly() method

opt=3 - only a given path is visualized. This is automatically set by

TGeoVolume::DrawPath(const char *path) method

The current view can be exploded in cartesian, cylindrical or spherical coordinates : TGeoManager::SetExplodedView(Int_t opt). Options may be :

Volumes themselves support different visualization settings :

Checking the geometry

Several checking methods are accessible from the volume context menu. They generally apply only to the visible parts of the drawn geometry in order to ease geometry checking, and their implementation is in the TGeoChecker class from the painting package.

Checking a given point.

Can be called from TGeoManager::CheckPoint(Double_t x, Double_t y, Double_t z). This method is drawing the daughters of the volume containing the point one level down, printing the path to the deepest physical node holding this point. It also computes the closest distance to any boundary. The point will be drawn in red.

geom_checkpoint.jpg

Shooting random points.

Can be called from TGeoVolume::RandomPoints() (context menu function) and it will draw this volume with current visualization settings. Random points are generated in the bounding box of the top drawn volume. The points are classified and drawn with the color of their deepest container. Only points in visible nodes will be drawn.

geom_random1.jpg

Raytracing.

Can be called from TGeoVolume::RandomRays() (context menu of volumes) and will shoot rays from a given point in the local reference frame with random directions. The intersections with displayed nodes will appear as segments having the color of the touched node. Drawn geometry will be then made invisible in order to enhance rays.

Geometry checking.

  • if option contains 'o': Optional overlap checkings (by sampling and by mesh).
  • if option contains 'b': Optional boundary crossing check + timing per volume.

STAGE 1: extensive overlap checking by sampling per volume. Stdout need to be checked by user to get report, then TGeoVolume::CheckOverlaps(0.01, "s") can be called for the suspicious volumes.

STAGE 2: normal overlap checking using the shapes mesh - fills the list of overlaps.

STAGE 3: shooting NRAYS rays from VERTEX and counting the total number of crossings per volume (rays propagated from boundary to boundary until geometry exit). Timing computed and results stored in a histo.

STAGE 4: shooting 1 mil. random rays inside EACH volume and calling FindNextBoundary() + Safety() for each call. The timing is normalized by the number of crossings computed at stage 2 and presented as percentage. One can get a picture on which are the most "burned" volumes during transportation from geometry point of view. Another plot of the timing per volume vs. number of daughters is produced.

◆ FindNextBoundary()

TGeoNode * TGeoManager::FindNextBoundary ( Double_t  stepmax = TGeoShape::Big(),
const char *  path = "",
Bool_t  frombdr = kFALSE 
)

Find distance to next boundary and store it in fStep.

Returns node to which this boundary belongs. If PATH is specified, compute only distance to the node to which PATH points. If STEPMAX is specified, compute distance only in case fSafety is smaller than this value. STEPMAX represent the step to be made imposed by other reasons than geometry (usually physics processes). Therefore in this case this method provides the answer to the question : "Is STEPMAX a safe step ?" returning a NULL node and filling fStep with a big number. In case frombdr=kTRUE, the isotropic safety is set to zero.

Note : safety distance for the current point is computed ONLY in case STEPMAX is specified, otherwise users have to call explicitly TGeoManager::Safety() if they want this computed for the current point.
