A new way of rendering CG skin that looks far more realistic than any previous attempts.

If your machine is man enough, click through (vimeo logo) to vimeo and d/l the app. Let it run to the end then play with the controls. Click/drag the head to move it about. Mouse wheel to zoom. Also move lights etc. Zoom in on the back of the head, past the skin to see the eyes & nostrils from the inside.

How long before Skyrim, crysis, COD etc. use tech. like this? It was not too long ago that Doom amazed us with its graphics that seem so `8 bit` these days. I do hope I live long enough to see it.

On the other hand, how hard will it be to tell real from fake? Some of the possibilities down that road are a little worrying.

That is some very dramatic music for some very boring video.

@Vimto: this is _real time_. As in, this stuff that took hours on a render farm is now doable on a standard gaming PC at regular frame rates.

@Vitmo - SSS has indeed been around for a while, this however is being rendered in realtime.

Everyone commenting on the model needs to realise this is a realtime SSS test meaning we`re supposed to be looking at the skin and only the skin. A sphere with the skin shader applied could have been used instead.

As far as render times - this was rendered in realtime using a fast GPU. You can download the test on his vimeo link and run it yourself.

and how long did those shots take to render?
still... wait for some more generations of chip performance and it will be cellphone stuff...

Erm ... hasn`t this idea been around for a few years now? I certainly remember it being talked about quite a while back.

But this is also worlds away from being used in a game or movie because of all the other complex processes that would need to be applied along with it. This is also a stationary object and not a dynamic model. This is an astounding breakthrough in 3d rendering but still a long long ways off from anything useable.

Yea great, now wait for them to animate such a face and realize how the skin effect only goes `skin deep` in realism. They need to focus on animation quality more.

They have reached an impressive level with dims surfaces but the real problem are still the tranparent ,liquid and reflecting surfaces. In fact this model have eyes closed, i would like to see how they realize it and also how they realize big surfaces of water for example. Also eyebrows are not so good here.

SSS is not a new way of rendering Skin. It`s been around for a good while.

This however is sub surface scattering which is being rendered in Realtime instead of pre rendered footage. Is it practical? Well in some ways yes - but SSS is used in movies and cutscenes where everything is rendered out in passes and composited together.

still looks fake. while the neck and some of the cheek look real, the eyes don`t. here is no color or bump where the eyes are. there`s no wrinkle where the eye closes. and while the idea is nice, they didn`t animate it and he was too glossy. but it`s getting there.

:\ the only thing that changed in real time was the lighting effects, other than that it`s a completely static 3D model... and no mention of the spec requirements

Just wait 10 years and it will be impossible to tell the difference between CD and reality.

Skin looked like plastic. It was missing all the fine, tiny hairs. Also no eye lashes.

But definately better than SIMS.

You can actually download the demo and try this interactively. It`s pretty impressing to someone who knows what this is.
