title: Displaying .dcm files with XTK's X.volume()
body: <p>According to the <a href="http://jsfiddle.net/gh/get/library/pure/xtk/lessons/tree/gh-pages/15/#run" rel="nofollow">lesson 15</a> I pass <code>.dcm</code> file to the <code>volume</code>. I get no errors (e.g. no parsing errors I faced before) but nothing is displayed. What could be wrong with the <code>.dcm</code> files?</p>
  
  <p>Here is a excerpt of the code I use:</p>
  
  <pre><code>function demo(file){  
    var _dicom = [file];
    var r = new X.renderer3D();
    r.init();
  
    var v = new X.volume();
    v.file = _dicom.map(function(v) {
      return file;    
    });
  
    r.add(v);
  
    r.render();
  
    r.onShowtime = function() {
      v.volumeRendering = true;
    };
  
  };  
  </code></pre>
  
  <p>I pass the full file path here. Well, I'm not sure it's a correct wording, but I'd lile to know, what dicom settings or parameters could cause such a behaviour, no errors and no diplayed data. Thanks in advance.  </p>
