class ZSliceSource : public interp::LazyValueSource<NF>

Supplies the function values of a z slice on demand, for lazySliceConstZ()

value(i,j) is exactly what buildSliceZ() stores at mesh point (i,j): f at z plane k0 directly for an exact match, and otherwise zInterp()[i,j] evaluated at the sz coordinate interpolated between planes k0 and k0 + 1 with weight t.

Public Types

using FView = std::mdspan<const double, std::dextents<size_t, 4>>: Type of Mesh3DInterpolator::f()

using SzView = std::mdspan<const double, std::dextents<size_t, 3>>: Type of Mesh3DInterpolator::sz()

using ZInterpView = std::mdspan<const std::unique_ptr<Interpolator1D<NF>>, std::dextents<size_t, 2>>: Type of Mesh3DInterpolator::zInterp()

Public Functions

inline ZSliceSource(const FView f, const SzView sz, const ZInterpView zInterp, const size_t k0, const double t, const bool exact)

Construct a ZSliceSource.

Holds views of the mesh’s heap buffers rather than a pointer to the mesh itself, so it stays valid if the mesh is moved; the buffers must outlive this object.

Parameters:

f – The sliced mesh’s f() view
sz – The sliced mesh’s sz() view
zInterp – The sliced mesh’s zInterp() view
k0 – Index of the (lower) z plane
t – Interpolation weight between planes k0 and k0 + 1
exact – True if the slice is exactly at plane k0

inline auto value(const size_t i, const size_t j) const -> std::array<double, NF> override

Return the function values at one mesh point of the slice.

Parameters:

i – Index of the point in the x direction
j – Index of the point in the y direction

Returns:

The NF function values at mesh point (i,j)
