[x3d-public] Hyperlink and form support

Here’s the beginning of 2 textfields (top and bottom sphere).

This is when you start wanting the textarea or textfield to wrap around the sphere.

Hi Albert,
Let me focus on one of the problems we encountered to make my point. On out platform, as example on one of the 3D websites, we wanted to allow text chats among visitors in the 3D environment. Therefore we needed an equivalent of a textarea to popup in the 3D space, with text wrapping, scrollbars and the possibility to set the text cursor at any required place by clicking on the text. 

In this example, do you wish the text chat window to be a full 3D object that is positioned in 3D space? This would be something that has front, sides, and back; so it would be possible to move around/away/towards the object. This would be (in concept) putting an HTML textarea on a 3D object in your virtual space. Another alternative would be to overlay the HTML textarea region over the virtual space creating a heads-up display. 

In the first case, the chat region is part of the virtual space and needs to interact and be controlled by VR application. In the second case, the chat area remains under HTML control. Whatever controls the VR space would interact with the application through the normal DOM interface. The second case has the advantage of being able to draw upon all of the tools of the browser to assist the user, especially if the user is disabled and requires (for example) sight to text handling.

XSeen was designed and built with full HTML integration. There is one online example that comes close to your concepts, through it uses fixed labels rather than a textarea -- https://xseen.org/example-capabilities/complex-test-scenes/#3. The labels are HTML div elements that can contain any HTML, including textarea. Control of the contents of each label region is completely through the DOM, so a 3rd-party text chat (or voice to text chat) could easily be used.

It seems to me that such a basic feature should be included in a future X3D version, and not be left as a quite challenging JavaScript implementation.
To me, it is in the very nature of the declarative approach to supply tags for these common features, although they will only become common when 3D will be used more for business implementations (not only as part of a 2D page).

Since X3D is presentation layer, and since X3D content can coexist within HTML and alongside SVG and exchange events throughout (see X3DOM and X_ITE implementations), there are many possibilities.  Given the flexibility of both HTML Script code and embedded X3D Script nodes, as well as common use of Javascript, all manner of integration appears to be possible today with more forthcoming.  Since the Anchor node activates the the powerful and diverse functionality of a url, much responsiveness is available even without scripting.

The X3D v4 specification evolution is aimed at good coexistence of 2D/3D/behavior markup for authors, emphasizing HTML5/DOM integration while adding a number of additional excellent features.  The X3D v4.1 specification will follow closely afterwards, adding functionality for virtual/augmented/mixed reality applications.  All this work is steadily progressing.  As ever with these specifications, hardware and software independence is achieved by defining page and model functionality rather than attempting to legislate browser software patterns (which morph regularly).  We no longer wait for "browser company permission" and instead utilize the shared declarative power of open standards.

Meanwhile for what you describe, the Anchor node is a powerful way to achieve form capabilities by associating url links with selectable geometry.  Vince is providing great guidance, you may also find KeySensor to be an even simpler variant that accepts single keystrokes, rather than strings.

Further links to resources for each node are found in X3D Tooltips.  X3D Scene Authoring Hints should also be useful.

Please don't get stuck, trouble reports and progress reports are all welcome.

Good luck with your work, it sounds interesting!  8)

This means that 3D website builders should be able surround a (part of a) text, an image or a 3D object with an anchor. Also one needs normal text fields, radio- and checkboxes etc. for users to be able to fill-in their choices and post back to the server.
