"Real or Sim?" My best guess is that if it looks even more beautiful and better than real life, a computer probably did it

[@DinmaSalitzey]

It cannot be. Real life definition is determined by your eyes which are the same eyes you percieve simulated imagery and computer screen. To make better than real life you don't need better graphics or screen but better eyes.

These simulations are getting to the point that, sincerely, by the time we have BCIs that allow for "true VR" like Matrix or SAO, we will likely have a really hard time telling that it is a "fake" world. It may at times feel different from the real world, but it will feel just as deep and complex. And that is mindblowing that this is the order in which we will get those technologies.

[@system128]

As it is now, it looks crazily realistic! If it absolutely had to be improved, a thing I noticed that could be improved on is the textures of the objects as they look a lot smoother when compared to a real image! I'd imagine the next paper relating to this could be that more realistic. Although, I can see why that wasn't their focus as it is a paper on surface tension. Either way, this paper does a phenomenal job at what it does!

Of course the computational characteristics of a more general solution would be interesting it what they imply, versus a somewhat cherry picked simulation that "looked like reality'. Maybe it's just me, but I won't be that impressed until CG simulations look like the dirty and grimy entropic mess you find on the inside of a rubbish bin, with simulated mold evolution symbiotically sustaining digital vermin, instead of some squeaky clean and delicious semi-submersible stone fruit lol.

I am firmly convinced that there will one day be a virtual reality indistinguishable from physical reality. Maybe it takes 100 years, but it will happen someday. High res VR + this quality of simulation + techniques used by the Unreal Engine for virtual production... it will happen. Watch the video of the Unreal engine production set where the background moves dynamically to match the perspective changes of the camera. We have almost all the technologies, just need exponentially faster hardware to combine them.

Now this makes realistic shipbuilding simulator/games a reality, perhaps we could simplify a bit to make it run in realtime for everyone's PCs, damn the simulation reality is getting real.

[@sanjeen2503]

those pushpins should be attracted way more faster when they get close. The water surface should also rise at the contact point of the two pins.

[@PASHKULI]

The sharp pin sinks a bit perfectly vertically, which does not happen in reality, because of the unequal water overflow on its perimeter (means, when sinking it should wobble a bit to one side at least). But nevertheless - great visualisation!

[@flurishart612]

I wish Houdini had this ability. I recently tried a simulation with fluid interacting with RBD where I wanted them to both have an effect on each other but it didn't seem like their was a way to easily do that. Had to go about it in a hacky way.

My thought precisely. That's why I stopped by in this thread. I'm not saying that it's an original thought. But having realistic simulations at hand IRL, rather than as abstract gedankenexperiments of Plato or some Buddhist monk, is a trigger that forces the unimaginative among us to take that possibility seriously.

The edges of the paperclip give it away being a simulation. Check the bottom left side of the paperclip edge with the water for the biggest anomaly. Huge artifacts. And the lighting on the leaves is also not fully realistic, kind of looks plastic to me. Otherwise they are impressive feats in the surface tension.
