Playing with the settings on the left is a good way to frighten small children.

Both awesome and creepy!

etherealG• 12 years ago

creepy, but awesome

Has some strange black flickering (screenie http://i.imgur.com/dUOSudN.png).

I'm a webgl developer and WebGL works perfectly fine otherwise (no crappy driver, no crappy GPU etc.)

Browsers: Firefox 26/27 and Chrome 32/33 (error visibile in all)

OS: Linux Ubuntu 13.04

GPU: GTX-780

Driver: nvidia 331.20

sparky• 12 years ago

Same in Chrome 34, Ubuntu 13.10, GTX Titan, NVIDIA 331.49.

LukeShu• 12 years ago

To add another datapoint: It works fine here.

Browser: Iceweasel-libre 27.0.1

OS: Parabola GNU/Linux-libre (i686)

GPU: Integrated Intel (specifically, device code 14c0:005a)

Driver: 'i915' module

I sort of suspect that it is a "crappy driver" that works fine in all common cases, but has a bug in a seldom used feature.

Aaaand, it's down.

"Requires WebGL" in Firefox Aurora.

Argorak• 12 years ago

Reload multiple times, the server seems to be hammered. I got that error 2 times, 2 times a black screen and then it worked.

TobbenTM• 12 years ago

    >Reload multiple times, the server seems to be hammered.

I wonder why ;)

frik2• 12 years ago

I got the same message with IE11 too. I saw the eye without texture in Firefox & Chrome. Probably, the webserver gets hammered - the "HN effect".

azakai• 12 years ago

It just shows that during load, I think. I saw it, then it worked (this is on Firefox Nightly).

venus• 12 years ago

To me seeing "requires WebGL" indicates that some sort of check has been carried out and the current browser has failed. Not really good as a loading message, IMO...

_random_• 12 years ago

It basically requires the Web GL plugin (which is not a part of standards). Some newer versions of _some_ browsers seem to have it built in. This is called "Open Web".

matthewmacleod• 12 years ago

WebGL is a standard: http://www.khronos.org/webgl/

It's supported in the current version of all major browsers except Safari on iOS.

Way to go! The site is down!

watermarkcamera• 12 years ago

the site is ok !

72deluxe• 12 years ago

Haha, very good but the cornea bulging control is pretty grim.

stuaxo• 12 years ago

Are the colours meant to look like heatvision / crazy rainbow ?

girvo• 12 years ago

Give it a bit, for me it eventually loaded the textures and BAM: creepy eye staring at me, sans-LSD.

cfontes• 12 years ago

looks aweomse but in a classic HN top 5 reaction... It's down.

frik2• 12 years ago

years ago, it was known as Slashdot effect or slashdotting: http://en.wikipedia.org/wiki/Slashdot_effect

Can we call it the HN effect?

ableal• 12 years ago

Can we call it the HN effect?

We can, but a more general term would be more useful.

Crowd crashed?

maccard• 12 years ago

It can also be called the reddit hug of death.

rkuykendall-com• 12 years ago

Also known, lovingly, as the "reddit hug"

kevrone• 12 years ago

Holy crap.

elefont2• 12 years ago

While it looks impressive, i don't think 'raytraced' is the correct term - i suspect it is just rendered

corysama2• 12 years ago

"Ray traced" probably refers specifically to the shader in the lens running a tiny ray tracer to optically distort the view of the iris.

mistercow• 12 years ago

That appears to be correct if you look here: http://www.vill.ee/entry.php?17-GLSL-shading-in-WebGL

Texture raytracing to simulate cornea refractions

alceufc• 12 years ago

Maybe it is really ray-traced. Notice that the simulation allows you to control camera focus and aperture.

Freaked me out for a second because the backing image looked a lot like my living room :P

Crito• 12 years ago

Same here, my eyes immediately flicked up to look at my webcam's indicator light.

Aqueous• 12 years ago

Freaked me out because the eyeball looks a lot like my eye ball :-)

codezero2• 12 years ago

pheo• 12 years ago

I'm really impressed with this (now that it has loaded).

I do have a qualm, hopefully taken as constructive criticism and not nit-picking:

The cornea and the aqueous humor are going to have different IORs and because this doesn't appear to be modeled, the iris is unrealistically distorted at sharp angles.

Otherwise, this is amazingly, disturbingly realistic. Good job.

Why doesn't GPU hardware do native path tracing now? People (well at least 1 person) is/are using general purpose GPUs to do path tracing at almost real time. If they created GPUs with cores specifically for path tracing then we could have real time path tracing as soon as that was engineered. Whoever made this brigade 3 thing, I wish nvidia or ATI would hire him. http://www.youtube.com/watch?v=abqAanC2NZs

The PowerVR guys are working on it now that they bought https://www.caustic.com/ http://www.imgtec.com/powervr/powervr_openrl_raytracing_tech...

Otoy hired him instead http://render.otoy.com/ http://raytracey.blogspot.com/

ilaksh2• 12 years ago

OK thanks. Then I guess I hope nVidia or AMD license it from Imagination or buy Otoy.

Please add webcam support so you can reflect the user in the eyeball.
