Template Parameters

VectorT – the SIMD type to be loaded

Parameters

source – scalar array to be loaded from

Returns

SIMD datatype

template<typename T, EnableIfFloating<T> = 0>
inline T genericload(const T *source)

Function that allows VectorTriple to load a scalar coordinate.

Template Parameters

T – the type to be loaded (float or double)

Parameters

source – scalar array to be loaded from

Returns

scalar value

template<typename T, unsigned char stride, EnableIfFloating<T> = 0>
inline void genericidxload(const T *source, const std::size_t *idxs, T &x, T &y, T &z)

Function that allows VectorTriple to load into a scalar datatype from a coordinate array by index before deinterleaving.

Template Parameters

• VectorT – the SIMD type to be loaded

Parameters

• source – scalar coordinate array to load from

• idxs – indices for the coordinate array

• x – x coordinates are returned in this scalar

• y – y coordinates are returned in this scalar

• z – z coordinates are returned in this scalar
