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;
