title: How to mirror a Matrix3D?
body: <p>I want to mirror my drawing.</p>
  
  <p>I need to mirror my Matrix3D for this i think... But I don't have a clue to do this.</p>
  
  <p>I tried like this:</p>
  
  <pre><code>  var transformation = sceneCamera.TransformationMatrix;
    var invertedTransformation = transformation;
    invertedTransformation.Invert();
  
    var trans = Transform3D.Identity.Value * transformation * invertedTransformation;
  </code></pre>
  
  <p>But this doesn't work.</p>
  
  <p>As you see in the image the drawing in the report has to be mirrored.</p>
  
  <p><strong>Thanks in advance!</strong></p>
