I would've liked a computational comparison between the "hard" and soft bodies. Something along the lines of "hard bodies only need to make 1 colission check while the soft body has to do(for squre example, 64 colission checks and 174 spring force calculations" And then showcase the limit before it start lagging with hard bodies and compare it with softbodies. Anyway great video. I like this new type of video.
That's a good observation. You can actually see the frame-rate dip below 60 in a few sections if you really look for it. In sections that featured multiple soft-bodies (mainly the ending shots) I actually remove them completely once the camera leaves to save performance. The stress balls (yes I know...) contain ~600 particles and ~7000 spring connections alone. I've used GPUs to get a set of 10,000 springs working above >150 fps in real-time, but didn't want to redo it for this project.

1:12 As a fighting game player, I believe that they are trying to go in and out of their opponent's attack range, baiting the other to do an attack, only for them to swing and miss, to hit them with an attack of their own. This is known as "whiff punish baiting" and is an important element of the neutral game.
How would you handle keeping a consistent volume? When you have a body of multiple springs they can keep a general structure, but the volume of the area can vary wildly which can lead to some pretty wacky looking objects.
I don't think I've seen any soft-body simulations that have figured this out yet. I imagine it would be significantly more complicated, since you'd have to actually calculate volume and apply an outward force equal to any inward force acting on the object.
Im pretty sure you have to play with general spring formula and force percents to get each individual effect Man, coding is suffering 😢 Edit: did a typo
If it's a sack of fluid, simulate the fluid or follow the suggestion above and calculate volume and use that as "back-pressure" on any/all the springs. If it's something rubbery, the volume can only "escape" locally, not far away, so you'd need to distribute the pressure locally in the mesh (squeeze one spring, other springs attached to its nodes want to elongate)
@@ClaraCl2005 though i might have a suggestion. If u want to make rubber objects u need to have a center joint that will always push on other ones, and probably connect center joint to outside joints with weaker springs. Also if u want to make an object with different stiffness parts, like a broom, you could use center joints to keep the thing in place. Like, for the broom, make a center joint inside of the fiber mesh and attack those to solid joints in the handle or something, it will correlate deformation of the mesh with other ones so it wont completely flop on the side. This can also be applied to tails or even chains and anchors to some extent
Seeing this reminded me of just how complex the misaligned and open vertices were in Mario 64 and all its invisible walls, floors, and death planes. I can only imagine the chaos that would’ve ensued if there were soft body physics in that game
I've been faking water and cloth recently in unreal materials - because doing the real maths is too much complexity for a giant water world and a lot of sailing ships. rather than 'springs' between verts I've been using dampened and shifted sign waves. Works quite well, gives the illusion of cloth and water waves with a fraction of the maths. This soft body demo was very cool man, might have to use something similar for various flora and fauna.
@@coolkatboy6991 No idea! I assume it has something to do with his Patreon group? Maybe they have a "spot the card" challenge where they get Nitro or something.
You can solve most of jiggle physics on a character by rigging the giggly part to a ball constrained to a spring. The ball collides with the hard portions of the parent mesh or the skeleton. Another way is to have a physics active set of bones that are spring tied to the intended animation and the collisions/sudden jolts effect the child mesh
@@evaluator8906 it still uses soft body physics underneath the visible part,its not like flatout 2 where everything is a rigidbody with mesh deformation It uses soft body physics,using a special physics mesh (.jbeam format) and the beams connecting the nodes act as springs So,the game uses the soft body physics to (very simply put) deform the meshes,so they are completely different things,yes but in beamng they are connected to each other
Small factoid: The "Air Dancer" (US Patent US6186857B1) is officially referred to as an "inflated undulating figure". Peter Minshall came up with the idea, and Doron Gazit helped realize it, then patented the design without Minshall. They were created for the 1996 Summer Olympics and are known by several names, which include: FlyGuy, Tube Man, Sky Dancer, Tall Boy, Inflatable Man, and (my favourite) "Wacky Waving Inflatable Arm-Flailing Tube-Man".
the thing at the end, i always heard people call it the "wacky arm-flailing inflatable tube man" and despite how comically long of a name that is, its accurate enough so thats what ive been calling it too 🤣
i may not understand all of this math stuff but as a 3d artist i gotta say these videos are awesome. from the editing to the jokes and the actual information. keep it up :3

This video is really fun and engaging, I would normally get bored with these topics, but the animations and humor helped me keep hooked and interested!
You have forced me to recall my computer modelling course rather than my artificial intelligence course for today, and I am equally confused and amused by the explanations I used to understand. How dare you, and good on you, dude. I wrote a paper trying to explain these concepts. Man, I sucked at it.
VERY awesome video. Informational, and hilarious as always! Thanks for making it! If you're interested, we took a completely separate approach to soft body physics in our game, INK INSIDE. Basically, we baked soft body "squash & stretch" movements into fixed animations. This took a fairly complicated animation rig to pull off, but it saved us massively on performance hits as no physics calculations are done when characters are getting hit by physics objects. Instead, every animation is "pre-made" to perform as if it was a soft body all along. The animation is "canned," but we use a variation of them with minor adjustments so the action appears organic. However, the only reason we can get away with it is because of our art style. (Cal arts / Saturday Morning cartoons). But I figured it was worth mentioning as an option when it comes to making rigid things squash & stretch in a game :)
really like this style of content! As a small hint/request: it would be interesting and funny to see programming mistakes that lead to funny outcomes. Not too much, but just some unexpected gags or cool visual things
An elegant way of testing whether a point is inside an enclosed N dimensional surface is to cast a ray in a random direction starting at the point, and seeing how many times the ray intersects the surface. Each time the ray intersects the surface it has to cross over from inside to outside or vica versa, meaning that if there are an odd number of intersections then the point must have been on the inside. Though the binary tree method scales better with complex meshes
