title: Convert Cortona VRML to X3D
body: <p>I want to convert a VRML file exported from RapidAuthor to X3D, so that X3DOM can read it.</p>
  
  <p>Problem : Cortona VRML is extended ; I tried many software (aopt, X3D-Edit and Meshlab for ex.) but none could convert it (it crashes or just cannot perform).</p>
  
  <p>Did anyone already succeed it ?</p>
