XMStoreXDec4 function (directxpackedvector.h)

Stores an XMVECTOR in an XMXDEC4.

Syntax

void XM_DEPRECATED XM_CALLCONV XMStoreXDec4(
  [out] XMXDEC4   *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  Min = {-511.0f, -511.0f, -511.0f, 0.0f};
static const XMVECTOR  Max = {511.0f, 511.0f, 511.0f, 3.0f};

assert(pDestination);

N = XMVectorClamp(V, Min, Max);

pDestination->v = ((uint32_t)N.v[3] << 30) |
                  (((int32_t)N.v[2] & 0x3FF) << 20) |
                  (((int32_t)N.v[1] & 0x3FF) << 10) |
                  (((int32_t)N.v[0] & 0x3FF));
