TGeoNavigator Class Reference

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:

R__EXTERN TGeoManager * gGeoManager
TGeoNavigator * AddNavigator()
Add a navigator in the list of navigators.
Bool_t SetCurrentNavigator(Int_t index)
Switch to another existing navigator for the calling thread.
Class providing navigation API for TGeo geometries.

path to current node

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

Definition at line 2612 of file TGeoNavigator.cxx.

◆ FindInCluster()

)
protected

Find a node inside a cluster of overlapping nodes.

Current node must be on top of all the nodes in cluster. Always nc>1.

Definition at line 2114 of file TGeoNavigator.cxx.

◆ FindNextBoundary()

TGeoNode * TGeoNavigator::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.

Definition at line 620 of file TGeoNavigator.cxx.

◆ FindNextBoundaryAndStep()

TGeoNode * TGeoNavigator::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.
