I see increased activity on the PlayCanvas forums though. I could talk about that some. They convert formats like OBJ to JSON and then display it in their games. They have a web-based development environment where you can arrange your assets in 3D and where you can import external blender generated (and other generated files) into PlayCanvas and have them converted on their server. Except for assets, the site is pretty much a JavaScript site, and I don’t think they rely much on DOM. I think they have a JavaScript library built on top of WebGL.</p><p class=MsoNormal>So not declarative, except for assets. A nice way to compose items in 3D, similar to Blender and Unity3D. Their shader model seems to work well, but I had to change my uniform names to get my shaders to work.</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Frankly, I think “the managers” are limiting us to old and current versions of Internet Explorer, if I wanted to bet on it.

Already there are alternative</p><p class=MsoNormal>>>>>> markup languages emerging that attempt to do what X3D has been doing</p><p class=MsoNormal>>>>>> for decades: create an HTML like language for 3D graphics. GLAM is</p><p class=MsoNormal>>>>>> an example proposed by Tony Parisi, and most recently Mozilla’s</p><p class=MsoNormal>>>>>> A-frame, released 3 weeks ago, both attempting to speak in the</p><p class=MsoNormal>>>>>> language of web developers to bring VR/AR to the browser.</p><p class=MsoNormal>>>>>><o:p> </o:p></p><p class=MsoNormal>>>>>> I am very frustrated in the lack of progress of the Working Group in</p><p class=MsoNormal>>>>>> developing a specification for X3D V4. There are number of issues</p><p class=MsoNormal>>>>>> that have been raised about the fundamentals of designs of X3D that</p><p class=MsoNormal>>>>>> appear to be incompatible with an HTML/DOM environment. A partial</p><p class=MsoNormal>>>>>> list includes the following:</p><p class=MsoNormal>>>>>> * name-scope handling</p><p class=MsoNormal>>>>>> * scripting</p><p class=MsoNormal>>>>>> * interfaces to the nodes and fields through the DOM API</p><p class=MsoNormal>>>>>> * event handling</p><p class=MsoNormal>>>>>> * profile structure and contents</p><p class=MsoNormal>>>>>> * newly supported formats (geometry and media)</p><p class=MsoNormal>>>>>><o:p> </o:p></p><p class=MsoNormal>>>>>> Examples of X3D/X3DOM:</p><p class=MsoNormal>>>>>> <http://tools.realism.com/x3d-v4-issue-examples>http://tools.realism.com/x3d-v4-issue-examples </p><p class=MsoNormal>>>>>><o:p> </o:p></p><p class=MsoNormal>>>>>> There are other concerns about event model that are not expressed in</p><p class=MsoNormal>>>>>> these examples mostly due to being unable to create an example that</p><p class=MsoNormal>>>>>> clearly shows the problem. It does exists and you may see some of</p><p class=MsoNormal>>>>>> that in sporadic or jerky movement in the animation examples using</p><p class=MsoNormal>>>>>> X3DOM.</p><p class=MsoNormal>>>>>><o:p> </o:p></p><p class=MsoNormal>>>>>> I have a concept specification that is getting updated at</p><p class=MsoNormal>>>>>> http://tools.realism.com/specification/x3d-v40. The was first sent</p><p class=MsoNormal>>>>>> to the X3D WG in November and has had a couple of other discussions.</p><p class=MsoNormal>>>>>><o:p> </o:p></p><p class=MsoNormal>>>>>> My specific technical concerns with the specification are listed in</p><p class=MsoNormal>>>>>> the Author's Notes at</p><p class=MsoNormal>>>>>> http://tools.realism.com/specification/x3d-v40/authors-notes</p><p class=MsoNormal>>>>>><o:p> </o:p></p><p class=MsoNormal>>>>>> Most importantly, it is not clear to me who the WG believes is the</p><p class=MsoNormal>>>>>> target audience for the specification and how the specification will</p><p class=MsoNormal>>>>>> meet that audience’s needs.</p><p class=MsoNormal>>>>>><o:p> </o:p></p><p class=MsoNormal>>>>>> As Co-Chair on Sabbatical and current member of the WG, I need to</p><p class=MsoNormal>>>>>> take some responsibility for not getting there. I have been working</p><p class=MsoNormal>>>>>> on developing a new specification and the beginning of an</p><p class=MsoNormal>>>>>> open-source web-based application for building scenes in the new</p><p class=MsoNormal>>>>>> specification. The web application is called “Basx3D - 3D the HTML</p><p class=MsoNormal>>>>>> Way”. I have posted an article about it’s initial release -</p><p class=MsoNormal>>>>>> http://realism.com/blog/basx3d. This post and one describing the X3D</p><p class=MsoNormal>>>>>> V4 proposal are publicly available.</p><p class=MsoNormal>>>>>><o:p> </o:p></p><p class=MsoNormal>>>>>> The application is targeted at web developers who do not need to</p><p class=MsoNormal>>>>>> know the details of creating an X3D by hand. The concept was based</p><p class=MsoNormal>>>>>> on Unreal Engine and Unity editors. I will be continuing development</p><p class=MsoNormal>>>>>> of both the application and proposal on a frequent and regular</p><p class=MsoNormal>>>>>> basis. Basx3D and the proposed specification function as a two-way</p><p class=MsoNormal>>>>>> development effort with Basx3D reflecting the proposal and providing</p><p class=MsoNormal>>>>>> implementation information and experience back to the specification.</p><p class=MsoNormal>>>>>><o:p> </o:p></p><p class=MsoNormal>>>>>> Although outside of its scope, the WG must be aware of the audience</p><p class=MsoNormal>>>>>> to which the standard is written, and the audience to which the</p><p class=MsoNormal>>>>>> standard is being promoted. This concept is crucial to the future</p><p class=MsoNormal>>>>>> adoption of X3D and should ultimately be agreed upon by the BOD, but</p><p class=MsoNormal>>>>>> the WG needs to understand and follow this strategy which will</p><p class=MsoNormal>>>>>> ultimately influence prioritization of WG activity.</p><p class=MsoNormal>>>>>><o:p> </o:p></p><p class=MsoNormal>>>>>> I am firmly committed to an open, royalty free, ISO ratified</p><p class=MsoNormal>>>>>> standard that communicates 3D data and its behaviors over networks,</p><p class=MsoNormal>>>>>> especially the dominant global network which is the internet, and</p><p class=MsoNormal>>>>>> which universally supports HTML5. I don’t want to see the decades</p><p class=MsoNormal>>>>>> of work and passion that have been invested in the standards</p><p class=MsoNormal>>>>>> maintained and promoted by the Web3D Consortium relegated to the</p><p class=MsoNormal>>>>>> corridors of obscurity. Because of many trends in software and</p><p class=MsoNormal>>>>>> hardware, a nexus of opportunity has been created like never before</p><p class=MsoNormal>>>>>> of which we can take advantage to catapult the Consortium’s</p><p class=MsoNormal>>>>>> standards to significant global adoption.
