title: How to convert XMFLOAT3 to const float *pData?
body: <p>I have the following code:</p>
  
  <pre><code>XMFLOAT3 normalized_direction = XMVector3Normalize(direction);
  pEffect-&gt;GetVariableByName("g_CameraDirection")-&gt;AsVector()-&gt;SetFloatVector(normalized_direction);
  </code></pre>
  
  <p>I want to pass XMFLOAT3 in const float *pData ?</p>
