XMStoreU555 method

Stores an XMVECTOR in an XMU555.

Syntax


VOID XMStoreU555(
  [out] XMU555   *pDestination,
  [in]  XMVECTOR V
);

Parameters

pDestination [out]

Address at which to store the data.

V [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 = {31.f, 31.f, 31.f, 1.0f };

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

  pDestination->x = (int8_t)N.v[0];
  pDestination->y = (int8_t)N.v[1];
  pDestination->z = (int8_t)N.v[2];
  pDestination->w = (int8_t)N.v[3];


Note these are not normalized values. To convert to the RGBA 5/5/5/1 format, you must scale the input vector by (31.f, 31.f, 31.f, 1.f). Also, you will probably need to swizzle the standard .x = RED, .y = GREEN, .z = BLUE, .w = ALPHA color vector's .x and .z value since the GPU format is BGR (not RGB).

Platform Requirements
