Title: too computer-generated?
Post by: René on June 12, 2020, 07:01:18 am
Hmm... sometimes, while I'm experimenting, textures like this emerge. I usually reject them because they look too unlikely and too computer-generated. :P

So many artefacts. The nature was asleep that day. :P

I still think it's pretty amazing what you get out of TG, rockwise. Maybe it's the lack of small debris and too smooth lines. If you would be able to mask certain areas and add some rubble, and break smoothness by tiny warp or displacement locally, it would be perfect!

looking around lately on some rocks formation, these are quite nice, thats a photo, to me it doesnt look that computer generated (in terms of shapes).
That picture is really nice, must be a pain to reproduce it in Tg :)

I was gonna scream genius!  ::) I didn't realize it was a picture!

I was kind of fooled too, thought René had a new rock, actually. He could have, that's for sure. But it would still need some work :P

I think I started a topic about sharing images like this which we would "reseed" thinking they're wrong. This is definitely one of them.

I'm sorry, I should have mentioned it's a picture. When I did a google search I first saw the thumbnail picture and thought: hey, computer generated. It wasn't until I opened the picture that I realized it was real. I had no intention of fooling anyone.

Maybe this is too philosophical now, but I have made the experience that most of the "landscapes" you can generate in the computer are reality somewhere. I have already designed the "most impossible" sceneries for my Space Art pictures and yet later I had to realize that these landscapes exist in a similar way. Maybe it is related to the fact that the algorithms that calculate these landscapes in such programs are somehow universal. A lot of things have to do with fractals and chaos theory in some way, and the results may be "random", but still have a "predictable" background. So perhaps the phrase "too computer-generated" does not even exist... Even "flying rocks" like in Avatar could exist somewhere.

I agree. One of the most interesting books I've read on this subject is James Gleick's Chaos. Nature works with algorithms too.

You have a point. So everything we make is realistic, good to know ;D  (just joking)

There is a very interesting theory (quantum physics, not esotericism!) that says that everything you can imagine is reality somewhere and sometime. Maybe not in our universe, but in another (parallel) universe. "There is nothing that does not exist".

I am just wondering what about it makes it look CG? The holes you see are common in rivers with rapids. The currents cause sand to race around and drill them out over long expanses of time.

Yep, quantum theories are nuts. For example, also, every thought you have is uniquely coded to you, and now exists in quantum space forever, in a finite pool of data that could theoretically be drawn from. The paper I read even went further talking about how gasses in space, could align in such a way, that for a moment, consciousness is born enough for the entity to think "what am I?". This was based in a paper about AI and Consciousness, and what defines it. It was crazy. Talking about how rocks have memory, and stuff.

That's the Hugh Everett's (father of lead singer of the Eels) 'Many worlds' theory. Quantum mechanics works on probabilities, which suggests all outcomes are statistically possible, including a broken egg reconstructing itself.

Here's one lol

That's insane! I wonder what processes trigger such regular strata.

Here's something different: "lookalike CGI":

You want excessive displacements like in Terragen?

I don't remember seeing those (there are more photos there. Just click) :o

Man I actually wish I could render these sort of abstract broken disps in TG without the scanline effect, and exponential render time lol sometimes they care cool. Reminds me of C4D days.

This is so fascinating; the reason that structures form in a certain way is something that has puzzled me for a long time. Some rock formations look like man-made objects and others look like living organisms.
There is now a new theory that explains why this resemblance exists. If you can muster it to read; here the article on this subject. https://www.quantamagazine.org/a-new-thermodynamics-theory-of-the-origin-of-life-20140122/

A few quotes.
If a new theory is correct, the same physics it identifies as responsible for the origin of living things could explain the formation of many other patterned structures in nature. Snowflakes, sand dunes and self-replicating vortices in the protoplanetary disk may all be examples of dissipation-driven adaptation.
Wilson Bentley

Scientists have already observed self-replication in nonliving systems. According to new research led by Philip Marcus of the University of California, Berkeley, and reported in Physical Review Letters in August, vortices in turbulent fluids spontaneously replicate themselves by drawing energy from shear in the surrounding fluid.

This is just concretion density with normal fluvial/abrasion erosion. Different densities of the sandstone erode at different rates. Doesn't have to do with sand in rapids. This is seen in areas void of running water and simple abrasion erosion from wind.

It's not that it looks CG, it's that in TG we may often reseed due to immediate chaos.

I wouldn't be surprised if film directors and production designers nowadays reject landscapes because they look too computer-generated, even when they're not. ;D

I've been wanting to tackle something like this for a long time. Good to see it's been achievable.
