#chladni plate

[dividedsingularity]

Various doodlings. "Murom zęby krat", a noise marine, a sword that was supposed to be Nightblood, Chladni plate patterns and just a pair of scissors.

[museqmeg]

My favorite detailed adaption Orange did for Trigun Stampede was using the concept of Chladni's plates to make the plant resonance in Trimax feel so real and beyond just basic sci-fi.

Not to mention the plant markings are simply beautiful.

So hear me out (this is all a big maybe): Plant-Song as a way to communicate, that manifests in their bodies

A Chladni figure these are created when a vibrating surface (usually a metal plate) is covered with sand and excited by different frequencies. The sand accumulates at the nodal points where there is no movement.

Now for comparison the Plant pattern we see in the Anime Opening:

And now as a comparison, the Plant markings in the manga, which display kinda similar characteristics, further reinforce this connection: (Manga spoiler)

If we analyze the pattern, in Stampede it could correspond to a higher frequency or a complex superposition of different vibrations. However, it is difficult to determine an exact frequency or a specific tone based solely on the pattern. Such shapes typically arise at certain harmonics, and if they are symmetrical, regular shapes, they usually correspond to sounds like sine tones. The shape could indicate a sound between 500 Hz and 2 kHz, which would fall into the range of high-pitched tones (e.g., violin or flute).

In the *Trigun Stampede* soundtrack, there is a song titled "Plant Song on Erhu" that would fit well within these frequencies.

In general, Plants can communicate through primitive sounds accessible to us, but they only do so in moments of extreme emotion, such as in Trigun Vol. 2 Ch. 9.

Additionally, communication through vibrations and frequencies would be far more efficient than the human linguistic. Let’s assume that the singing of their sisters falls below 20 Hz, into the infrasound range. In this case, they could communicate over thousands of kilometers without humans perceiving it.

The audible spectrum for humans covers less than 1% of all possible frequencies.

My theory is that the Plants use the dimension available to them as a kind of resonating body, and a shadow of their song is reflected into the lower dimensions through these intertwined vibrations. On top of that, other beings (especially those who have been enhanced) may possess the ability to sense the aura and emotions of the twins.

This would also explain why Vash can "feel" his twin. The terror WW repeatedly experiences could be linked to the idea that the experiments have improved him enough to partially perceive these frequencies, and/or that his instincts as Homo erectus are awakening, urging him to flee from the "predator" before it’s too late.

Additionally, the *Song of Humanity* mentioned in the manga would thematically fit very well with this idea.

Edit: This could also explain why Vash and Legato can communicate throu some kind of "telepathy". Maybe the blue mother fucker can also recieve/send out something similar to Plant-Song

They are angel-like beings that communicate through song, shaping their bodies with their tunes. I find that a very beautiful concept.

I know the theory has MANY holes, but I still thought it was worth writing about. Sorry when this theory is old.😅

Thank you for taking the time to listen.

Is JJ a Flying Polyp?

JJ FLYING POLYP PROPAGANDA

I am a Lovecraft fan and did you read his “The Shadow Out of Time”? I think that JJ has peculiar similarities to the Flying Polyp race.

(There, Flying Polyps were extraterrestrial race which devoured and exterminated another alien race named there as Yithians or The Great Race)

It’s just a speculation I made for fun, nothing special. Just compared two aliens. For fun.

1. I always wondered why no remains/prints of the Yithians were found anywhere (according to the lore of the story).

If the Polyps had the similar digestive tracts as JJ has, then there was nothing left of the devoured victim. Literally. They digest everything. No bones/cartilage/other hard parts for you, no waste products, they spit out metal or so as much as possible.

Devoured to nothing.

2. Returning to the first: the weapon of the Great Race against the Polyps. Polyps are only vulnerable to electricity. Jean Jacket, according to the canon, flies due to the electromagnetic field that he creates himself (obviously for this he has a special organ, I suspect it places somewhere on the sides and on the top like stingrays have), this is also why he interfered with the electronics. Let's say the Yithians used weapons that resonated/oppositely suppressed/something like that with the field of the Polyps. Then, if we consider JJ, these interferences not only deprived him of normal movement and they fell down, at least it could directly harm their organs, because if they flew due to this field, then it is clear that other systems of their body also depend on it. They could have been paralyzed by such a blow, or killed outright. That is, yes, this is indeed a very effective weapon against Jean Jacket

3. Polyps controlled the winds and other things. Well, everything is simple here: this is a beautiful metaphor for how JJ eats sand and creates winds and hurricanes. This is literally what he did in his spare time.

4. Polyps left huge marks on the ground (without touching it)

Idk, can we say that JJ has an image of a flying saucer? -> reference to crop circles -> back to the Polyp tracks? Maybe these traces are a consequence of the influence of the JJ’s electromagnetic field, which interacts to the surface sand when he flies close above the ground, like Chladni’s patterns

5. The polyps are semi-material and freely mixed through the air, and their shapes are indescribable.

Let's assume that the shape of a flying saucer is not necessary for the JJ-likes. In his open form, he indeed looks somewhat semi-material, and his body is very unusually shaped and truly indescribable.

And moving through the air is quite feasible for him thanks to the field + the fact that he is light.

6. But the saucer shape is already a modification, which allows him to quickly cut through the sky. Yes, exactly in the form in which he appeared in the end, he will not be able to fly quickly, this is the most non-aerodynamic form. But if he shrinks into a disk, it will be easier for it to fly at supersonic speeds. Let me remind you that he is probably very heavy, what makes a multi-ton predator need extra drag in an indescribable form. Plus it's easier to hide.

But the same Lovecraft had no talk of any plates. Well, yes, but they didn’t have to: there were a lot of them, you don’t need to hide or hunt, your crowd won’t drive you crazy

6. «…and of strange winds and whistling noises associated with them. And I thought of the tales, wherein the horror of great winds and nameless subterrene ruins was dwelt upon...» (quote from the story)

This is an addition to point 5 (winds).

But about the sounds: JJ has a very wide vocal range of sounds. In reality, they are whistling, clicking, grinding, etc.

«And all the while cold fingers of damp vapour clutched and picked at me, and that eldritch, damnable whistling shrieked fiendishly above all the alternations of babel and silence in the whirlpools of darkness around.»(quote from the story)

Those moments where JJ eats people are really similar. It creates a wind current to suck in the victim.

7. Flying polyps are an aggressive and predatory species. It is unknown how intelligent they are. Having no vision, they felt in some special way through any matter.

Yes, Jean Jacket is very aggressive. Fact. Especially if you make a visual contact with him. But even without this, he's crazy.

Yes, in the film's FD, of course, it is generally accepted that Jacket is just an animal. I used to think so too. But now it seems to me that his behavior is more aggressive than animalistic. At the very least, he did some things and clearly did them on purpose. Yes, destroying the Jupe’s show is an act of aggression. Drenching OJ's house with blood (intentionally! He deliberately vomited all over his ranch) is an act of aggression. Gobbling up a reporter and flying above OJ, while the guy is screaming inside Jeans' stomach is an act of aggression. And much more, as well as the intonation of some of its sounds. Yes, JJ is not a ruthless monster. But then he clearly went on the offensive and tried to show his dominance here. This also supports the first scene of the film with Gordy: the monkey lived calmly until he went crazy from the constant abuse and killed everyone. In fact, JJ demonstrates aggression only for the reason that your “attention” to him drives him crazy and he is mad, cuz that Jupe allegedly “deceived” him. That is, we clearly have awareness and he enjoys his “revenge.”

And he is mad by the fact that they are looking at him, it drives him into rage, just like Polyps.

Or how aggressively he behaved when he saw the ball. The whole bitch is exhausted.

Remark: I know that all the actions of JJ also can be explained that he wanted to lubricate his throat/hungry/etc but let it be, of course that’s all true, I just want to note that the fact that he are the horse decoy instead of real horse made him suffer from pain and made him aggressive, really agressive towards the person who “fed” him before and the whole crowd from the SLE only made it worse

8. Lack of vision in Polyps. Yes, it seems like the plates don’t even have glasses (but he still has something like eyes, but it’s still, like, and these “eyes” are well hidden)

Found your work. You inspired me to take another shot at technical art and graphics programming. Do you recommend any specific resources for getting started and beyond?

Thanks so much! Really glad I could inspire you to do that bc graphics and tech art things are so much fun :D

(Also sorry for the late response. I've been a bit busy and was also thinking about how I wanted to format this)

I'm mostly self taught with a lot of stuff and have done lots of research on a per-project basis, but Acerola and Freya Holmer are two of my favorite channels for learning graphics or technical art things. Shadertoy is also an amazing resource to not only create and view other's shaders, but learn about algorithms and see how people do things!

While I don't have many general resources. I'll steal these resources for graphics programming that Acerola shared in his discord server:

For getting started with graphics engine development: DX11: https://www.rastertek.com/tutdx11s3.html OpenGL: https://learnopengl.com/ DX12: https://learn.microsoft.com/en-us/windows/win32/direct3d12/directx-12-programming-guide Vulkan: https://vulkan-tutorial.com/

For getting started with shaders: catlikecoding: https://catlikecoding.com/unity/tutorials/rendering/ the book of shaders: https://thebookofshaders.com/ daniel ilett's image effects series: https://danielilett.com/2019-04-24-tut1-intro-smo/

For getting started with compute shaders: Kyle Halladay: http://kylehalladay.com/blog/tutorial/2014/06/27/Compute-Shaders-Are-Nifty.html Ronja: https://www.ronja-tutorials.com/post/050-compute-shader/ Three Eyed Games (this one teaches ray tracing AND compute shaders, what a bargain!): http://three-eyed-games.com/2018/05/03/gpu-ray-tracing-in-unity-part-1/

I also wanted to talk a little bit about I do research for projects!

A lot of my proficiency in shaders just comes from practice and slowly building a better understanding of how to best utilize the tools at my disposal, almost like each project is solving a puzzle and I want to find the most optimal solution I can come up with.

This is definitely easier said than done and while a lot of my proficiency comes from just doodling around with projects and practicing, I understand that "just practice more lol" is a boring and kinda unhelpful answer. When it comes to projects like my lighting engine, I came up with a lot of the algorithm stuff myself, but there were certainly lots of details that I learned about from past projects and research like ray marching (calculating the ray intersection of a distance function) and I learned about the jump flood algorithm from a tech artist friend (calculating distance functions from textures)

Each new algorithm you learn in various projects ends up being another tool in your toolbox, and each project becomes a combination of researching new tools and applying the tools you've learned in the past.

One last example. I made a Chladni plate simulation in blender (that thing where you put sand on a metal plate and play noises and it makes patterns) and it started with me researching and looking up chladni plates, I watched youtube videos related to why the sand forms the patterns it does, which ended up being due to how the sound waves displaced the plane. I googled some more and found the actual equation that represents it, and used it to simulate particle motion.

Figure out some projects you want to do and just do some googling or ask for help in game dev discord servers or whatever. Lot's of research on a per-project basis is honestly how you'll learn the most imo :3

CYMATICS Science Vs Music

On July 8, 1680, Robert Hooke was able to see the nodal patterns associated with the modes of vibration of glass plates. Hooke ran a bow along the edge of a glass plate covered with flour, and saw the nodal patterns emerge.

The German musician and physicist Ernst Chladni noticed in the eighteenth century that the modes of vibration of a membrane or a plate can be observed by sprinkling the vibrating surface with a fine dust.

Everything is frequency, everything is energy, everything is not what it appears to be. It's time to change your thinking⁉️🤔

CYMATICS: Science Vs. Music - Nigel Stanford

This Nigel Stanford video is essentially a "greatest hits" of physics-based audio visualization: Chladni plates, Hose pipe, ferro fluids, Ruben's tube, tesla coil lightning... 

You’ve probably seen at least some of them before, it’s nicely done.

I just realized that the plant markings were a very early concept. Tajima's concept art was one of the first things Studio Orange had done in Trigun Stampede's production; having him reference Oxi's novel of No Man's Land's 150-year history.

I think it's a safe guess that Oxi was the one who used the idea of Chladni's plates for plant resonance from the manga and Tajima came up with the designs we see here and in the final product.

Reading the Bernardelli Times from the English Blu-Ray and seeing the production timeline laid out got me going down this rabbit hole.

Things I love about Rings of Power:

- The intro. Using Chladni plates to show the song of the Ainur, Melkor's rock 'n roll included, is fucking awesome. Go physics!

- It makes me feel like a scholar, maps and family trees displayed all over my desk to follow the characters. Confession: marked with pencil the illustrated edition s maps. Nerd me is giddy.

- Talking to the characters like old friends, because of course they are. Not suffering about the changes, and delighting in the depictions.

- Allowing myself to feel sad beforehand.

- Voluntarily deciding to focus on the happiest story while ignoring all the beautiful landscapes that'll be ruined, the people who'll fall, and the inevitable rise of the psycho. I prefer to see Gandalf and the Harfoots discovering the weed.

Cymatics, this phenomenon occurs when sound waves of particular frequencies are played through a metal plate causing it to vibrate which creates geometrical shapes in the sand. If frequencies can change the shape of sand, what else can they change?

Artist Research : Ernst Chladni

Ernst Chladni (1756–1827) was a German musician and scientist who made significant contributions to the study of vibrations and acoustics. Chladni, who was born in Wittenberg, Germany, made important advances to our knowledge of sound and the mechanics of vibrating plates and membranes. The contemporary study of resonance and acoustics was made possible by his work.

In Chladni's most well-known work, sound waves were visualised using what are now referred to as "Chladni patterns" or "Chladni figures." He showed how the particles will arrange themselves into clear geometric patterns when a thin layer of sand or other small particles was sprinkled over a vibrating plate and then exposed to particular frequencies. These patterns gave rise to a visual depiction of the standing waves on the surface by revealing the nodes and antinodes of the vibrational modes.
