WebVR is Easy with A-Frame

About a week ago, I got my first set of VR goggles. Nothing fancy – it’s the Samsung Gear VR. I explored some of the demos. (great fun!) Some of what I explored was WebVR, which just became available on Gear VR (without the use of “experimental browsers”) a couple of weeks ago – albeit with a “deprecated API”. (which means, an old obsolete version.) Then I took a crack at a tool called A-Frame.

WebVR is easy with A-FrameA-Frame makes WebVR easy. Easy peasy. It reminds me of X3DOM – it’s a “declarative language”, so it drives a lot like HTML5. All of the things you declare when you’re using A-Frame get added to the “DOM” (Document Object Model), so everything in your “world” can be accessed and manipulated just like you would the elements on a plain, old-fashioned web page. Which, really, makes a lot of things easy. Easy peasy.

The Dawn of WebVR and Gear VR

I don’t always try to get to the bottom of a new technology before there’s commercial demand for it. But when I do, it’s because the potential of a technology really stands out. And that’s the case with the dawn of WebVR.

The dawn of WebVR and my Gear VR gear
Note the “ENTER VR” button. Yes please!

I’d tried a bunch of the WebVR demos on my flat monitor. Yup, that provides a 3D experience like anything from VRML on. But the kick with WebVR is that your 3D stuff can get rendered either on a monitor, or in a VR headset.

Two weeks ago, this happened:

Mobile VR and the Web (which is already mobile)

If 87% of VR headsets in consumers’ hands (or on their heads) are mobile VR – then the experiences we create will have to give good UX on mobile VR.

I’m a web guy, and I’m fascinated by the onset of VR. And as a web guy, I’m convinced that mobile VR will be essential to the 3D web.

I was considering picking up some of the high-end VR goggles and experimenting with technologies like WebVR. Trouble is, the high-end ones need a heavy-duty computer to even function.

Mobile VR - Google Cardboard
Mobile VR – Google Cardboard

The “easy way” to get into VR these days is with mobile VR. Mobile VR is really just a piece of plastic (or cardboard) with some lenses that you attach to your smartphone, to experience “low end” VR.

Based on a number of factors, I’ve decided to take the plunge into mobile VR, and leave that high-end stuff alone for now.

First up – the web is already mobile. Much of the last decade has been spent coming to grips with the fact that people use the web everywhere on all manner of hardware. The way websites are built has evolved considerably to take this into account.

But here’s the kicker:

VR for Web Developers

So you’re a web developer, and you’ve been hearing things about VR. I’m also a web developer, and I’ve also been hearing things about VR! And I’ve been blogging about it. Not just VR – but how VR is very likely to soon become both a crisis and an opportunity for web developers. So what are the prospects for VR for web developers?

The dawn of virtual reality.Today is April 8, 2016. The Oculus Rift and the HTC Vive both tried to start shipping in the last couple of weeks – and it’s been a bit of a mess. But even so, eager early adopters have raved up and down that this revolutionary technology finally actually works.

A Virtual Reality Web – Elegant Descriptions and Pessimistic Outlook

Given that VR goggles have been available to consumers for DAYS, not even weeks, and given that the only people who have even heard of the Oculus Rift are gamers and sports fans, I think all the pessimism about a “virtual reality web” may be a little bit premature. Or so I’d like to think, anyway.

I saw this article today about a “virtual reality web” – and was amazed at both how forward-thinking, and pessimistic it was.

http://www.fastcodesign.com/3058591/why-a-virtual-reality-web-may-never-happen

The opening paragraph paints a pretty elaborate picture of something that’s, well, science fiction:

What if you could browse the web in virtual reality? Just imagine the potential. Hyperlinks could take you not to Wikipedia pages about history, but right to the landscapes of ancient cultures, immersing you in plagues and art and war. Recipe sites could give you smell-o-vision cooking simulations. Message boards could become face-to-face chats. The web as we know it could become tangible, interactive, and more immersive than ever.

Blend4web vs. Three.js

As a sequel to my Feb 23 post X3DOM vs. Three.js, I’d like to quickly compare Blend4web vs. Three.js, using that same old arbitrary VRML file as a neutral sample. Blend4web is an add-on for Blender, the open-source 3D authoring tool I use.

Here’s how the Blender workspace containing my old VRML file looks when I export it using Blend4web:

And here’s the same Blender workspace exported as a COLLADA file and then imported into Three.js:

You can drag your mouse on either of those to move them around. Each button gives you a different motion when you drag. Each example uses each button in a different way.

Happy April Fool’s from Blend4web??

Oh, man, I saw this in my Twitter feed this morning, from Blend4web Community, and the cognitive dissonance is rolling through my head like virtual thunder.

Unity Technologies Switches to Blend4Web for its WebGL-Based Solutions

April Fools Blend4web
The black and white “Spy vs. Spy” appeal of this graphic re-enforces my belief that this is some kind of (clever) April Fool’s joke. But, may as well blog about it before I find out for sure…

Virtual Worlds vs Virtual Reality

What is the difference between a virtual world, and virtual reality?

A virtual world is a fake place you can visit. Virtual reality is an immersive way of experiencing virtual worlds.

The difference between virtual worlds vs virtual reality is kind of like the difference between a web page and colour monitors. A virtual world, like a web page, is a container of content. A VR headset, like a colour monitor, is a way of looking at content.
