Detailed Description

Track a particle within an axes-aligned rectilinear grid.

Member Function Documentation

CELER_FUNCTION auto celeritas::RectArrayTracker::initialize ( LocalState const & state ) const

inline

Find the local volume from a position.

To avoid edge cases and inconsistent logical/physical states, it is prohibited to initialize from an arbitrary point directly onto a surface.

CELER_FUNCTION real_type celeritas::RectArrayTracker::safety	(	Real3 const &	pos,
		LocalVolumeId	volid
	)		const

inline

Calculate nearest distance to a surface in any direction.

On an axis-aligned rectlinear grid the minimum distance to any surface is always always occurs along a line parallel to an axis.
