I'm seeing nothing except the background and the logo & links in the top left on both Chrome (27.0.1453.110 m) and Firefox (21.0) on Win8 64bit.

Console:

GLOW.Attribute.constructor: Unreachable attribute? Please activate GL.drawArrays or split into multiple shaders. Indexed elements cannot reach attribute data beyond 65535. GLOW.js:67

.WebGLRenderingContext: GL ERROR :GL_INVALID_VALUE : glGetActiveUniform: index out of range empaempa.github.io/:1

.WebGLRenderingContext: GL ERROR :GL_INVALID_VALUE : glGetActiveAttrib: index out of range empaempa.github.io/:1

Not working for me either running Chrome 27.0.1453.110 m

Same, latest chrome gives me:

Doesn't work in latest FireFox either (downloaded just now)

Running great on Chrome 28.0.1500.36 beta, Linux 3.8.13 with AMD catalyst version 12.6. Also working in Firefox 21.0, albeit with about half the fps.

Same Error here Chrome 27.0.1453.110, and Firefox 22.0 both on Win7.

Seeing the same unreachable attribute message in Firefox 23.0a2 (current Aurora) on Windows 7.

Worked for me in Chrome 27.0.1453.110, Ubuntu 13.04

Turning the web, the only viable cross-platform solution, into something that works only for a certain OS / browser / graphic card combination is a bit unfortunate.

There are other cross-platform solutions, and insomuch as GLOW is advancing the state of the art in cross-platform-foot-shooting, it mostly treads a path already well bloodied by the limping of oh so many plugins and browser DOM/Styling quirks.

Isn't it fortunate that we're finally seeing proper 3D graphics being brought to "the only viable cross-platform solution"? How exciting will it be when it spreads to more OS / browser / graphics card combinations and approaches ubiquity!

AFAIK the impetus is mostly on the various graphics chip vendors to make sure that their OpenGL implementations are consistent, just as it is on browser developers to implement web standards correctly.

Click to change the animal. Anybody recognizes the 7th one?

Think it is the seal..

Thanks! That was not evident at first :(

(I like the bear the most)

Working for me in Firefox (latest version) on Mac, though I don't much see the point of it...

May I ask why you need a 'point' to something like this? It's pretty and the technology behind it is pretty cool.

Well, it just seems like "yet another technical feat that doesn't mean all that much"... There have been many posts like this over the years and I was just expressing that I'm at a loss as to why they're all that attention-worthy at this point.

Anyone (smart) can put together a neat demo that does something different. If they had, let's say, built a whole game with this, I'd be more inclined to be impressed! But yet another toy proof of concept? Meh. I mean, it's cool, but...

Perhaps I'm just overly blasé today...

Maybe it's not for you, but it looks to be a good intro to the GLOW library http://i-am-glow.com/?page_id=183

Oh, and it's always nice to revisit http://www.ro.me/ which is where the models come from.

Diden't work in my Chrome. Running latest version. Did only see the background, logo and links in the top left corner. Shortly after the PC become super slow for about 10-15 seconds, then the browser closed the tab.

Chrome version 27.0.1453.110 m on Windows 7 64 bit with 8 gb ram and a Nvidia GetForce 8600 GTS 3d card.

Not sure if this has been posted here before, but this is also a really cool WebGL demo:

Everything is done in the fragment shader, no vertex data is used at all.

Hmm - doesn't seem to work for me in Chrome OR Firefox. Am I missing something?

Doesn't work for me in Chrome. Firefox displays a moving square made of triangles and "particles".

Working in latest Firefox Dev on Ubuntu. I suspect it needs some new features not in stable builds yet.

Edit: And it's really interesting too. It's great to see particle effects starting to speed up in browsers.

This is from 2011, part of the building of the ROME (http://ro.me) WebGL demo.

Works beautifully with Chromium 25.0.1364.160 on Ubuntu 12.04 (25.0.1364.160-0ubuntu0.12.04.1)

Doesn't play with Chrome running in a VM. Worked fine with Chrome 27.0.1453.110 for Mac.

Firefox had a problem and crashed ... version 24.0a1 (2013-06-10)

Doesn't work in latest Firefox on Windows 7.

Beautiful, but really hurt my head!

Works fine in Safari.
