Detailed Description

Numeric data from volume data files.

Member Function Documentation

◆ get_clone()

auto ray_tracing::NumericData::get_clone ( ) const -> std::unique_ptr< BackgroundSpacetime >

inlineoverridevirtual

Copies the background spacetime. Must call initialize on the clone before using it.

Implements ray_tracing::BackgroundSpacetime.

◆ initialize()

void ray_tracing::NumericData::initialize ( std::array< double, 2 > time_bounds )

overridevirtual

Initialize the background spacetime, e.g. by reading data from a file.

This function is called before the first call to variables(). It is valid to call initialize again with new time bounds. Derived classes must guarantee that the variables function can be called from other threads while initialize is running (e.g. loading new data from files), but only with times within the overlap of the previous and the new time bounds.

Parameters

time_bounds The time bounds for which to initialize the background spacetime. The spacetime should be valid for all times in this range.

Reimplemented from ray_tracing::BackgroundSpacetime.

◆ time_bounds()

std::array< double, 2 > ray_tracing::NumericData::time_bounds ( ) const

overridevirtual

Time bounds for which the background spacetime is valid. The variables function can be called for any time in this range (inclusive).

Reimplemented from ray_tracing::BackgroundSpacetime.

◆ variables()

tuples::tagged_tuple_from_typelist< tags > ray_tracing::NumericData::variables	(	const tnsr::I< DataType, Dim, Frame > &	x,
		double	t,
		std::optional< gsl::not_null< std::vector< size_t > * > >	block_order = `std::nullopt`
	)		const

overridevirtual

Returns all spacetime variables at a given point in space and time.

This function must be thread-safe.

Parameters

x	Spatial coordinates
t	Time
block_order	Optional priority order for processing blocks during interpolation. If specified, it will be updated to push the block in which the point was found to the front. Can be empty, in which case it will be initially set to the default order. See `block_logical_coordinates` for more details.

Implements ray_tracing::BackgroundSpacetime.
