XMLoadFloat3PK method

Loads an XMFLOAT3PK into an XMVECTOR.

Syntax


XMVECTOR XMLoadFloat3PK(
  [in]  const XMFLOAT3PK *pSource
);

Parameters

pSource [in]

Address of the XMFLOAT3PK structure to load.

Return value

Returns an XMVECTOR loaded with the data from the pSource parameter.

Remarks

The following pseudocode demonstrates the operation of the function.



  XMVECTOR vectorOut;

  float xscale = powf( 2, (float)pSource->xe - 15);
  vectorOut.x = ((float)pSource->xm / 64.0f)*xscale;

  float yscale = powf( 2, (float)pSource->ye - 15);
  vectorOut.y = ((float)pSource->ym / 64.0f)*yscale;

  float zscale = powf( 2, (float)pSource->ze - 15);
  vectorOut.z = ((float)pSource->zm / 32.0f)*zscale;
  
  vectorOut.w = 0;

  return vectorOut;
