XMStoreUByte4

Stores an XMVECTOR in an XMUBYTE4.

Syntax

void XMStoreUByte4(
         XMUBYTE4 *pDestination,
         XMVECTOR V
)

Parameters

pDestination
Type: XMUBYTE4 *

[out]

Address at which to store the data.

V
Type: XMVECTOR 

[in]

Vector containing the data to store.

Return value

None.

Remarks

The following pseudocode demonstrates the operation of the function.

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

assert(pDestination);

N = XMVectorClamp(V, XMVectorZero(), Max);
N = XMVectorRound(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];
