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

<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 />
</div>
</blockquote>
<p><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 />

Just when I needed some special things like Force Feed back in a

some Scripting or Prototyping.<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>

<div>Do you mean HMDs / head mounted displays? And 'data

<div>I think it's not hard - the hard part is ... buying the

<div>I've had freewrl running on an android phone with

<br />
Thanks for all hints received so far.<br />
<br />
However my main question was about VR.<br />
<br />
Are there any plans or is it already possible to use
X3D Players with VR equipment?<br />
<br />
Does it make a difference whether I use "native" X3D
Players (Contact, Instant Player, Castle Game Engine,
......) or "WebGL based" X3D Players.<br />
<br />
I will myself face this question actually earliest in
2020 I admit, but I thought having some answers on
X3D-public could also help other People.<br />

<div>Hi all,</div>
<div> </div>
<div>When I will be finished with my application
(alpha release "not before 2020"), then I will
have a nice little Visual Basic Application
for .NET/Windows integrated with an X3D Scene
played on BS Contact, made multiuser capable
by BS Collaborate.</div>
<div> </div>
<div>Besides some licensing questions (will my
users like to pay for BS Contact? will at
least one of my users be willing to buy and
run BS Collaborate) I will have some other
questions:</div>
<div> </div>
<div>What about VR?</div>
<div> </div>
<div>Will it be possible to go downstairs to the
VR Cafe and tell the people: here's a nice
collaborative application, where everybody can
bring his/her own content. Can we play it on
your hardware?</div>
<div> </div>
<div>Will I need to rebase to another X3D
Player? Instant Player? Free Wrl? X3DOM?
X_ITE? Castle Game Engine? ...?</div>
<div> </div>
<div>Any hint welcome.</div>
<div> </div>
<div>Thanks in advance</div>
