You could also use these techniques as steering behaviors for a group of autonomous agents? Each agent is a point on the segment. It'd be like a team doing a dragon or lion dance.

Re: A simple procedural animation technique [video]
#12I hope the author sees this. Dude, your video is so awesome, thank you! But your microphone is "popping" every time you say a 'P' or a 'T' sound. This is because you are speaking directly into it. Try talking "past" it instead. Your vocal sound goes out in all directions, but the "wind" from your mouth that creates the pops only goes in one direction -- straight forward -- so if you slide your microphone to the side,…
Thanks, I didn’t know about that technique. I’ll definitely fix it for the next video! I was on a time crunch while making the voiceover for this one. I didn’t have a pop filter and thought I could get away with a software de-plosive. Turns out popping is pretty difficult to fix without warping or trimming audio.
I'm going to level with you, I can't hear the popping noise. It just sounds like someone talking.
Maybe don't stress too much about it?

#13Had no idea about the FABRIK technique, that looks really useful in a lot of different contexts too. I did a little clap irl at the end of the video.

#14Great video -- any complementary resource that can help a young learner get started? What tool might one use to do such animations?

I'd recommend starting with the book "The nature of code", if I recall correctly, a new version was published very recently

#16Beautiful video. I would love to see this animation technique combined with an evolution simulation similar to Karl Sims' Evolved Virtual Creatures project: https://youtu.be/RZtZia4ZkX8?si=vxQ904w_CNXsSoj5 Previous HN discussion: https://news.ycombinator.com/item?id=30719801
Jefferey Ventrella has a few programs along those lines
Re: A simple procedural animation technique [video]
#17This is very well made video. That said, the animations don't actually move like real snakes or real fish. Animals don't move from the head and drag the rest of their bodies behind them with constraints on circles. They pull/push with muscles though out the entire length of their body.

In fact not only do they not drag their behinds, the tails turn further than the bodies
Snakes: https://www.youtube.com/watch?v=zEto1-ZTbd4
That's not a dis. The technique in the video is pretty to watch and might be good enough but it just stuck out to me at a glance as unnatural. Like something was off.
Re: A simple procedural animation technique [video]
#18The animations are less realistic grounded, legless, critters and more accurately things being dragged (without seeing whats dragging them). That said, engaging, concise, and well produced video. The technique also comes to life when legs are added. Maybe thats obvious.

The beauty of procedural animation is not thas it's realistic, but that very simple principles allow for good-enough results. It's something used for videogames or presentations, not simulations.
TL;DR: animation by simplistic algorithms is a beautiful technique, but a lousy simulator.
Re: A simple procedural animation technique [video]
#20Great video. Much more complicated, but checkout Godot "fish" in the docs.

> The animation will be made of four key motions:
A side to side motion
A pivot motion around the center of the fish
A panning wave motion
A panning twist motion
