But if an X3D Player was willing to support HMD like navigation, then the X3D standard would not forbid it, true?<br>

        That sounds good. So have I got it correctly?<br />
        <br />
        I need not expect major changes to my content. At least basic
        navigation and interactivity is ensured by existing X3D nodes
        like "NavigationInfo", "Viewpoint", "ProxiSensor",
        "TouchSensor", "PlaneSensor" and so on.<br />

    </p>
    <p>There is nothing in X3D that allows or requires HMD-like
      navigation. That would need to be an extension provided by the
      viewing application. Also note that TouchSensor and PlaneSensor
      are pointing-device sensors. For this to work (correctly) there
      must be something that functions as a pointing device (e.g.,
      mouse, wand, etc.) and the software needs to recognize it. <br />

    <p>In most cases you will need to do scripting when interacting with
      various sensor nodes. You usually want to do someone far more
      complex than can be done by sending events to various nodes.
      Protyping is frequently done for scene efficiency and/or content
      management, not necessarily just for "special things".</p>
