We definitely know how to make graphics look real - look at the unbiased renderers like LuxRender [https://luxcorerender.org/gallery/ https://luxcorerender.org/gallery/].
The problem is that we can't do that in 1/60 second on consumer-priced hardware, and also both scanning real objects and manually modelling are expensive.
- natdempk 6y agoWhich of those images look real to you? To me, pretty much all of them look strictly like rendered images or have some aspect of them which gives away the fact that they are rendered.
- CydeWeys 6y agoWe need a blind test where you evaluate a set of images on whether you think each one is real or rendered.
- natdempk 6y agoHeh, I agree! I'd love to try something like that if it exists.
- bonoboTP 6y agoWith a caveat: the real images should not be cherry picked to look as close to cgi as possible but the other way around. Real and render can look indistinguishable that way too, but we want real looking cgi, not carefully arranged cgi-looking reality. The biggest giveaway is the simplicity and pristine sterility of the rendered scenes, no mess, clutter, irregularity. Just look at photos that people haphazardly snap in the real world.pick those for a blind study and cgi is nowhere near. Pick carefully lit and arranged artificial scenes with heavy post-processing, like studio shoots or hotel brochures or car ads and the difference will be less obvious.
- CydeWeys 6y agoI love this idea. Quick question for you, is this scene real or rendered? https://imgur.com/a/MpKMo6j https://imgur.com/a/MpKMo6j If you think the answer is obvious, then CGI definitely has more work to do. If not ... ??
- bonoboTP 6y agoLooks real. The dirt on the computer, the curls of the books and magazines and many other small details look very real. If this is CGI, then I'm impressed and want to see more from where this came from.
- CydeWeys 6y agoAlas, it's real. Agreed with you that I'd be super impressed if anyone could render at that quality, but I haven't seen it yet.
- Sohcahtoa82 6y agoIn the version that is shrunk down to fit my browser, it kind of looks rendered, because you can't see the subtle details that another user mentioned. Dust, the curling of book pages, etc. But in the full version[0], it's clearly a photo. But it has been HDR'd which can sometimes create shading that gives a somewhat rendered look.

- nearbuy 6y agoThe full version also has artifacts from the camera that ironically give it away as a real photo. At full resolution you see this characteristic noise plus noise-smoothing effect that cameras apply.
- CydeWeys 6y agoThat effect would be much easier to fake with a digital filter than rendering the entire complicated scene from scratch, though. Adding noise and noise-smoothing is simple. So if that's your heuristic, then you're gonna be fooled by digital renders that just incorporate that simple to implement effect.
- 0xffff2 6y agoI think Instagram is actually helping this from the other direction. My brain processes the two Jeep pictures as real but with a heavy-handed Instagram filter applied.
- sillysaurusx 6y agoAgain, it's important to focus on video, not screenshots. Video is processed differently by the brain. "The Dress" illustrates how easy it is to fool people with still images. Movement gives crucial context. Our visual system has evolved for millions of years specifically to exploit that context.
- ACow_Adonis 6y agoalso, the style of photos most of us are used to seeing are so processed digitally before publication, there's a real question of what it means to have a 'real photo' to approach in the first place. That were capable of getting pretty close isn't that surprising, because most photos have already had N layers of digital effects applied, moving them closer to renders, rather than the other way around.
- SahAssar 6y agoI think that with a lot of work we can make a real scene that looks like those renders, but none of those look like a "normal" real photo.
- stan_rogers 6y agoDo any of those actually look real to you? I'm not saying that a convincingly realistic render is impossible, but those are all obviously synthetic to me. Maybe that's just a lifetime of photography at play.
- Sohcahtoa82 6y agoMeh...all of those are obviously renders. There's not enough contrast in the lighting in most of the interior shots, and overall surfaces just look too smooth.
