Detailed Description

template<typename G>
struct Acts::MaterialMapLookup< G >::MaterialCell

Struct representing smallest grid unit in material grid.

This type encapsulate all required information to perform linear interpolation of material classification values within a 3D volume.

Constructor & Destructor Documentation

MaterialCell()

template<typename G>

Acts::MaterialMapLookup< G >::MaterialCell::MaterialCell	(	std::function< ActsVector< DIM_POS >(const Vector3 &)>	transformPos,
		std::array< double, DIM_POS >	lowerLeft,
		std::array< double, DIM_POS >	upperRight,
		std::array< Material::ParametersVector, N >	materialValues )

Default constructor.

Parameters

[in]	transformPos	Mapping of global 3D coordinates onto grid space
[in]	lowerLeft	Generalized lower-left corner of hyper box (containing the minima of the hyper box along each Dimension)
[in]	upperRight	Generalized upper-right corner of hyper box (containing the maxima of the hyper box along each Dimension)
[in]	materialValues	Material classification values at the hyper box corners sorted in the canonical order defined in Acts::interpolate
