Your formulation is clearly superior. What I want to know is how I got from Count Dankula Mad Lads talking about cannibal serial killers, to whatever this is.
Me: minding my own business UA-cam: Hey kid, wanna see an explicit SPH formulation for incompressible linearly elastic solids? Me: Wut? UA-cam: Don't ask questions, just get in.
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.
I love that someone gets paid to hurl CG bunnies and ogres around in a virtual world in the name of scientific research! BTW great lighting and staging - it's not all about the science lol

its incredibly realistic looking and has a very natural motion, crazy, imagine this level of realism in VR video games in the future...it would be insane.
Martin S+ unfortunately thats true, at least I think we have a chance of being able to run this in complete real time in video games in the the future of like 15 years away or so.
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.
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!
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.
Eww the first one is so uncomfortable. It's like one of those videos where they cut an rubber-band-ball in half and it looks all wormy, except this time it is made of overcooked mince beef.
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!
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?
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.
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.
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?
I'm just trying to imagine the plot of the movie this technology was developed for. There's a brain made of worms being kept alive in a jar of nutrients. There's a set of bunny twins, one of whom has vibrators implanted in their ears. There's a chef whose face is never seen who makes armadillo soup. There's a strange glass box in which the armadillos in the soup are reconstituted into the original armadillos. Somebody keeps chucking giant pills at a bunny. And there's a really weird swimming pool orgy at the end. Is David Lynch working on his first CGI-animated film?
