Struct Documentation

struct Acts::MaterialMapper::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.

Public Functions

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

Material getMaterial(const Vector3 &position) const

Retrieve material at given position.

Return

Material at the given position

Pre

The given position must lie within the current cell.

Parameters

  • [in] position: Global 3D position

bool isInside(const Vector3 &position) const

Check whether given 3D position is inside this cell.

Return

true if position is inside the current cell, otherwise false

Parameters

  • [in] position: Global 3D position

Public Static Attributes

constexpr unsigned int N = 1 << DIM_POS

Number of corner points defining the confining hyper-box.
