Sounds about right. To be honest, we're pretty close to that. I've always dreamt of making ultra-realistic games and always wondered why no one has yet. I'm realizing it's because we don't have powerful enough processing power yet. I'm pretty excited for what the future of games will hold.
Official RXO+ well better and much faster computers are being developed as we speak, for instance there is that company called Optalysys which is developing optical processors which are significantly faster than traditional modern day PCs but unfortunately they are not aiming yet for mainstream and for gaming/CGI needs, its more for niche market and the likes, so right now its for scientists/medical tech/deep learning AI and so on, but maybe in the further future down the road so to speak we may see their optical processors being ultimately used by all for many purposes and even for gaming/VR simulations ETC...the future is exciting.
This is awesome! I can't wait for this to proliferate into the industry. It'll be awesome to see this move from demo to fully rendered in games and vfx.
So tell me if I get this right: I looked it up and found that SPH stands for smoothed-particle hydrodynamics. Basically it a way of simulating things that normally have trillions of particles - like water, by approximating it with relatively very few particles. By Incompressible it just means details of whatever it is can't be grouped together to be a single input of the physics function. Like each particle has to takes into account the effect of every other particle? Then a Linearly Elastic Solids is means that the elasticity of the object is the same throughout the entire object. So uh.. what does it mean by "Implicit"? how can you imply physics?
Implicit refers to the method they're using to solve the relevant differential equations. Explicit methods calculate the solution directly from the current state, while implicit methods calculate the solution iteratively within some tolerance. Implicit methods are typically more computationally expensive, but they are also typically able to handle longer time steps than explicit methods.
How was the fluid modeled? Was it also particle hydrodynamics? At 0:21 it looks like there are particles of water, but I wonder how many paticles you had to used relative to the solid bodies.
i swear youtube keeps recommending me these academic physics simulation videos. i have no fucking clue whats going on but im strangely addicted to them now
Are there any smoothed particle hydrodynamics applications already developed for industrial use? Like, I'd love to do some flow around a hull using this novel formulation.
Yes there are a bunch of commercial simulation softwares proposing SPH at the moment. It's not the most commonly used formulation because it's relatively young but it is for example used in conjunction with other formulations to simulate bird strikes on airliner engines.
I was really on the fence until 4 bouncy werewolves fell on some bunnies and balls in a kiddie pool (5:34). You just closed the sale Freiburg. Well done!
I notice you're not getting tearing in your models. Does this mean the distance between particles does not play as significant a part in the bond strength between them as you see in other formula?
Probably most of this technology will end up in Maya and other "industry standard" software, meanwhile Blender's soft body physics haven't been touched in years and all what it can do is bouncy balls of small scale.

I've always wondered whether they build up a proprietary 3d engine to show off these algorithms or they use something already available. No mention in the paper.
I think you should consider the scale of the experiment. For instance, the first video is implausible for a normal scale, maybe it is correct for a huge object. The videos are awesome, keep up the good work!
Amazing physics simulation! I wonder how much of a compute overhead this implementation incurs. It's one thing to brute force an accurate simulation in a very small system, it is another to come up with something that is practical to use on a commercial scale.
Its an implementation of their research paper ( onlinelibrary.wiley.com/doi/abs/10.1111/cgf.13317 ) in their preferable programming lang and then giving the output to a research oriented renderer like pbrt ( pbrt.org ) or Mitsuba ( www.mitsuba-renderer.org ). PS: Your videos are amazing!
Those dots, those balls. Are they geometrical? Like do they have vertices and lines and faces? Or are they just points that magically become balls by using shader magic?

SPH means Smoothed Particle Hydrodynamics. They are modelling solids as a type of liquid allowing for bouncier computer simulations.
The music at 2:13 is awesome!
