class TGeoNavigator: public TObject

 TGeoNavigator


   Class providing navigation API for TGeo geometries. Several instances are
 allowed for a single geometry.
 A default navigator is provided for any geometry but one may add several
 others for parallel navigation:

	TGeoNavigator *navig = new TGeoNavigator(gGeoManager);
	Int_t inav = gGeoManager->AddNavigator(navig);
	gGeoManager->SetCurrentNavigator(inav);

	.... and then switch back to the default navigator:

	gGeoManager->SetCurrentNavigator(0);

Function documentation

TGeoNavigator()
 dummy constructor
TGeoNavigator(TGeoManager* geom)
 Default constructor.
TGeoNavigator(const TGeoNavigator& gm)
 Copy constructor.
TGeoNavigator& operator=(const TGeoNavigator& )
assignment operator
~TGeoNavigator()
 Destructor.
void BuildCache(Bool_t dummy = kFALSE, Bool_t nodeid = kFALSE)
 Builds the cache for physical nodes and global matrices.
Bool_t cd(const char* path = "")
 Browse the tree of nodes starting from top node according to pathname.
 Changes the path accordingly.
Bool_t CheckPath(const char* path) const
 Check if a geometry path is valid without changing the state of the navigator.
void CdNode(Int_t nodeid)
 Change current path to point to the node having this id.
 Node id has to be in range : 0 to fNNodes-1 (no check for performance reasons)
void CdDown(Int_t index)
 Make a daughter of current node current. Can be called only with a valid
 daughter index (no check). Updates cache accordingly.
void CdUp()
 Go one level up in geometry. Updates cache accordingly.
 Determine the overlapping state of current node.
void CdTop()
 Make top level node the current node. Updates the cache accordingly.
 Determine the overlapping state of current node.
void CdNext()
 Do a cd to the node found next by FindNextBoundary
void GetBranchNames(Int_t* names) const
 Fill volume names of current branch into an array.
void GetBranchNumbers(Int_t* copyNumbers, Int_t* volumeNumbers) const
 Fill node copy numbers of current branch into an array.
void GetBranchOnlys(Int_t* isonly) const
 Fill node copy numbers of current branch into an array.
TGeoNode * CrossBoundaryAndLocate(Bool_t downwards, TGeoNode* skipnode)
 Cross next boundary and locate within current node
 The current point must be on the boundary of fCurrentNode.
TGeoNode * 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.
TGeoNode * FindNextDaughterBoundary(Double_t* point, Double_t* dir, Int_t& idaughter, Bool_t compmatrix = kFALSE)
 Computes as fStep the distance to next daughter of the current volume.
 The point and direction must be converted in the coordinate system of the current volume.
 The proposed step limit is fStep.
TGeoNode * FindNextBoundaryAndStep(Double_t stepmax = TGeoShape::Big(), Bool_t compsafe = kFALSE)
 Compute distance to next boundary within STEPMAX. If no boundary is found,
 propagate current point along current direction with fStep=STEPMAX. Otherwise
 propagate with fStep=SNEXT (distance to boundary) and locate/return the next
 node.
TGeoNode * FindNode(Bool_t safe_start = kTRUE)
 Returns deepest node containing current point.
TGeoNode * FindNode(Double_t x, Double_t y, Double_t z)
 Returns deepest node containing current point.
Double_t * FindNormalFast()
 Computes fast normal to next crossed boundary, assuming that the current point
 is close enough to the boundary. Works only after calling FindNextBoundary.
Double_t * FindNormal(Bool_t forward = kTRUE)
 Computes normal vector to the next surface that will be or was already
 crossed when propagating on a straight line from a given point/direction.
 Returns the normal vector cosines in the MASTER coordinate system. The dot
 product of the normal and the current direction is positive defined.
TGeoNode * InitTrack(Double_t* point, Double_t* dir)
 Initialize current point and current direction vector (normalized)
 in MARS. Return corresponding node.
TGeoNode * InitTrack(Double_t x, Double_t y, Double_t z, Double_t nx, Double_t ny, Double_t nz)
 Initialize current point and current direction vector (normalized)
 in MARS. Return corresponding node.
void ResetState()
 Reset current state flags.
Double_t Safety(Bool_t inside = kFALSE)
 Compute safe distance from the current point. This represent the distance
 from POINT to the closest boundary.
void SafetyOverlaps()
 Compute safe distance from the current point within an overlapping node
TGeoNode * SearchNode(Bool_t downwards = kFALSE, const TGeoNode* skipnode = 0)
 Returns the deepest node containing fPoint, which must be set a priori.
TGeoNode * FindInCluster(Int_t* cluster, Int_t nc)
 Find a node inside a cluster of overlapping nodes. Current node must
 be on top of all the nodes in cluster. Always nc>1.
Int_t GetTouchedCluster(Int_t start, Double_t* point, Int_t* check_list, Int_t ncheck, Int_t* result)
 Make the cluster of overlapping nodes in a voxel, containing point in reference
 of the mother. Returns number of nodes containing the point. Nodes should not be
 offsets.
TGeoNode * Step(Bool_t is_geom = kTRUE, Bool_t cross = kTRUE)
 Make a rectiliniar step of length fStep from current point (fPoint) on current
 direction (fDirection). If the step is imposed by geometry, is_geom flag
 must be true (default). The cross flag specifies if the boundary should be
 crossed in case of a geometry step (default true). Returns new node after step.
 Set also on boundary condition.
Int_t GetVirtualLevel()
 Find level of virtuality of current overlapping node (number of levels
 up having the same tracking media.
Bool_t GotoSafeLevel()
 Go upwards the tree until a non-overlaping node
Int_t GetSafeLevel()
 Go upwards the tree until a non-overlaping node
void InspectState()
 Inspects path and all flags for the current state.
Bool_t IsSameLocation(Double_t x, Double_t y, Double_t z, Bool_t change = kFALSE)
 Checks if point (x,y,z) is still in the current node.
 check if this is an overlapping node
Bool_t IsSamePoint(Double_t x, Double_t y, Double_t z) const
 Check if a new point with given coordinates is the same as the last located one.
void DoBackupState()
 Backup the current state without affecting the cache stack.
void DoRestoreState()
 Restore a backed-up state without affecting the cache stack.
TGeoHMatrix * GetHMatrix()
 Return stored current matrix (global matrix of the next touched node).
