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.
