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);

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 695 of file TGeoNavigator.cxx.

◆ FindNextBoundaryAndStep()

TGeoNode * TGeoNavigator::FindNextBoundaryAndStep	(	Double_t	stepmax = `TGeoShape::Big()`,

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.

Definition at line 1225 of file TGeoNavigator.cxx.

TGeoNode * TGeoNavigator::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.

Definition at line 1048 of file TGeoNavigator.cxx.

Returns the normal vector cosines in the MASTER coordinate system. The dot product of the normal and the current direction is positive defined.

Definition at line 1652 of file TGeoNavigator.cxx.
