XMStoreUByteN4 function (directxpackedvector.h)

Stores an XMVECTOR in an XMUBYTEN4.

Syntax

void XM_CALLCONV XMStoreUByteN4(
  [out] XMUBYTEN4 *pDestination,
  [in]  FXMVECTOR V
) noexcept;

Parameters

[out] pDestination

Address at which to store the data.

[in] V

Vector containing the data to store.

Return value

None.

Remarks

The following pseudocode demonstrates the operation of the function.

XMVECTOR N;	
static const XMVECTOR  Scale = {255.0f, 255.0f, 255.0f, 255.0f};

assert(pDestination);

N = XMVectorSaturate(V);
N = XMVectorMultiply(N, Scale);
N = XMVectorTruncate(N);

pDestination->x = (uint8_t)N.v[0];
pDestination->y = (uint8_t)N.v[1];
pDestination->z = (uint8_t)N.v[2];
pDestination->w = (uint8_t)N.v[3];
