<p>Christoph,</p>
<p>The standard allows for custom navigation extensions (see

15th paragraph -- starts "Browsers may create..."). Some features
may be prohibited or not explicitly allowed. The second case
allows for features that are not in the spec, but not explicitly
prohibited either.</p>

<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>

</blockquote>
<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>

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>
