Worlds merging: A video response from X3D

A few weeks ago, I posted a video showing how my Revit model was imported into realxtend by Visibuild.  It generated lots of interest and traffic, suggesting to me that model interoperability is an important priority for lots of us.

Shortly after posting that my friend Damon Hernandez, always a spirited supporter of X3D, asked if I would send him that same Revit model so he could demonstrate the capabilities of X3D.  The closest I had ever come to seeing some of the more current X3D applications in action is while exploring Vivaty or ExitReality, and I was excited to see what he could do with it.  24 hours later, he sent me this video showing that same model in several X3D based environments.  What an impressive and entirely convincing demonstration!  I had no idea X3D had come so far.

This is by no means an exhaustive demonstration of everything X3D can do, and is only intended to serve as an introduction.  But what I find most compelling is the fact that this model can retain its metadata, and theoretically retain its BIM data.  If we were to develop a fully interactive model of a building, visitors could drill through this metadata, clicking any material or product in the home and discovering specific information about each building component.  I’m told it could even be useful as a CAM model, whereby manufacturers could interpret this data and use robots to assemble the home in real life.

So, here I have a seemingly limitless range of opportunities at my fingertips, yet this model – even if it were fully textured and polished – would not be useful to me in real-life practice.  The design is far from final, and we are still ironing out several key features such as the living room ceiling, the front entry, and the fireplace/hearth.  If I’m working with X3D, I have the option of either 1.) waiting until the model is final before sending it to be imported  2.)  send several batches of different design ideas and have them all imported  3.) become an X3D geek, and figure out how to import it myself, so I can do so on-the-fly as we develop new ideas.

No matter how I approach it, it isn’t useful to me as a schematic design tool – nor is it necessarily intended, or ready to be used that way (yet).  So, we really are comparing apples to oranges.  It isn’t that one platform is necessarily better than another, but that they each hold value in different phases of the design process.  As you could see in the realxtend demo included in my first post, I was able to simply exclude parts of the design weren’t finalized yet, then use the in-world modeling tools to mock up several options to share with our clients.  Those elements can be edited in realtime, while the client is present – and we can cycle through lots of different material and color options.

When my model was first imported into Visibuild, it looked exactly like it does on this video – raw and unedited.  But the difference is that with Visibuild, I was personally able to log in and continue designing and testing new ideas.  Using prims to build really does feel like sketching to me, only better, and within the context of my Revit model that contained room sizes and plan layout that had already been approved.  I can also build the entourage myself, exactly the way I want it.  I can import 3D Warehouse models if I want, or from any range of stock 3D entourage resources available.  The key is that I can easily do it myself, and the learning curve is nowhere as steep as it would be if I wanted to do the same in X3D.

That doesn’t take anything away from X3D as an incredibly powerful technology.  In fact, it could be that it’s far too powerful for what I primarily use virtual worlds for.  As an open standard  ‘simulation level’ technology, its actually reaching down to enable multi-user and simple representation of geometry.  Its power lies in the ability to eventually attain things like simulation-level physics, and retention of  metadata.  This is surely the new frontier for architecture and virtual environments.  Once we achieve seamless interoperability of geometry, our next major priority will be seamless data interoperability so our ‘smart’ BIM models don’t have to become ‘dumb’ each time they enter or leave a virtual environment.

Until then, it seems there might be an opportunity for collaboration here.  I know nothing about the core technology at work behind all of this, but I do know that one of these world is currently best for pre-design and design development, and the other is better for final design visualization and post-design.  Could they ever meet half way?  Will X3D eventually include in-world modeling and collaboration tools?  Will realxtend models someday become simulation level technology and retain metadata?  If geometry and data become fluidly interoperable, will it even matter?

Great collaboration will continue to bridge these worlds! 🙂

Nothing really has change in x3d/vrml for the ways youve used it here in a decade:) Dont let the tools or service providers of any of these technologies guide your process of design too much:).

You suggested the need to be a X3D geek, well maybe yes, but then again, after 10 years of vrml/x3d I had to become a SL geek by that definition in order to deal with the “percieved” need to “provide design based on being” in SL, that clients that had used or passed on rt3d visualization for a decade, were forced to do, by PR way above the ability for SL to deliver as well.

Case in point, the Clothing manufactuer CEO , who was told by many, until she spoke to me, that in the “Metaverse of SL” she could have her VIRTUAL version of her annual 50,000 plus audience back to school fashion events held. Stadium style:)

X3D is a format, its not going to provide IN world modeling. Its just a data language thats ISO standard and open.

It seem to me following this blog that What your talking/searching for are tools for designers who want to work using rt3d media as a key media for their or their clients aims.

I suggest that neither LL or any company making “tools or services” around the X3d standard is in business to give designers what they need for their profession as a viable business model.From my POV this has been a 10 year plus issue for web3d and its media, I find talk of any mergers to benefit the designers process or profession/business premature when one dives deeper into the actual business plans of the companies youve mentioned.

How is a culture/society really better served by “American Idol” being broadcast only via Digital TV? 🙂
