Function blend¶

`function` blend(const vec<T, N> &, const vec<T, N> &, elements_t<Indices...>) simd ¶

template <size_t... Indices, typename T, size_t N>
KFR_INTRINSIC vec<T, N> blend(const vec<T, N>& x, const vec<T, N>& y,
                              elements_t<Indices...> i = elements_t<Indices...>())

Blends lanes from x and y according to a repeating selector pattern.

The index pattern i selects, for each output lane, whether to take from x or from y. A selector value of 0 picks x; a value of 1 picks y. The pattern is tiled across all N lanes.

Template parameters
Indices	Compile-time index list defining the per-tile source selection (0 for `x,` 1 for `y).`
T	Element type of the vectors.
N	Length of each input vector.

Parameters
x	First source vector.
y	Second source vector.
i	Selector pattern.

Returns
	A vector of length `N` blending lanes from `x` and `y.`

Fully qualified name: kfr::blend(const vec<T, N> &, const vec<T, N> &, elements_t<Indices...>)
