Amazing RESONANCE with Geometry Nodes - Blender Chladni Plate

[@mdoz]

This video helped me understand how to use equation in blender nodes, that I had problem implementing. Thankyou.

[@AllSquirrelsGoToHeaven]

My way until now has been to wrap a big balloon around a speaker, like a drum skin, and then fix a small piece of mirror glass to it. Then I shine a laser on a camera mount at the glass which reflects to a blackboard on my wall. After the setup vibrations captured by the rubber will move the glass and relay a cymatics lightshow to the blackboard. It blows my mind that I can do this virtually now too. I had no idea how awesome Geo Nodes actually is.

[@jasonselph6968]

this has made my day! I've waited for the ability to do this and now I'd like to make a 3D version with parametric controls and possibly audio input. Thank you for your time and knowledge!

[@thomasblack9038]

Yes I have the same idea

[@rayly7291]

This is simply amazing. You can explain complicated topics with ease!

[@Archi_Voxel]

amazing. Thank you so much. I've been making so so many music audio visualizer lately in blender, very satisfying and rewarding.

[@StrayCreations]

Great to hear! I can't wait until we can use MIDI files to directly drive these kind of nodegroups

[@Archi_Voxel]

@@StrayCreations totally!! Very sick idea. When you have time please check out my recent audio visualizer animations and give your honest opinion! What styles are best, what should I improve? Thanks!

[@DamielBE]

THIS would work PERFECTLY with @Curtis Holt 's By-Gen addon! one of the option in the Generation Labs pack creates voxels based on patterns. With the Chladni Place you could render any pattern and use it with By-Gen really fast, and creating your own voxel formations. What do you think?

[@StrayCreations]

Hi Denis, you can definitely turn this into a mesh without any addons by using the following nodes: Points to volume, Volume to mesh, Set shade smooth, set material. Then add a smooth modifier (something like factor 2.5 repeated 4 times should work) and you've got yourself a mesh!

[@DanielGGava]

Hello, that's a wonderful tutorial! I was wondering if it's possible to change these forms. I mean, attract the particles to specific shapes, maybe from a black and white texture, a 3D shape, or even a weight map on the plane.Thanks again, this is so cool.

[@StrayCreations]

Yes this is possible! You can use image textures in geonodes and use them as your input instead of the calculation

[@JS-yd4wd]

Awesome channel! Hopefully you'll read this, but as for what I'd like to see, here goes: I'd love in depth theoretical videos explaining geometry nodes, the math behind them (kinda like you did in this video) but where the nodes are explained-- what they do, how you can use them, etc. I've been working on a project I just can't get right and it's due to being new and not understanding the nodes or the math behind them. I know that's a lot to ask, but that's just my two cents. Anyway, great channel. Have a great one

[@StrayCreations]

Hey, thanks for your comment. Luckily I'm planning to make a video just like that, a consice video that actually makes you intuitively UNDERSTAND how geometry nodes work.

[@JS-yd4wd]

@@StrayCreations that's awesome! I can't wait to see it.

[@AllSquirrelsGoToHeaven]

So to get this to react realistically to music you would make this whole thing and then connect the epsilon to the output of an audio detector? To get a real cymatics effect you would need to change the underlying pattern according to the frequency right?

[@Jojojojo-py8ie]

I love your geo tutorial, it's very easy to understand

[@RonHicks]

I'm trying to make an animation of the oscilloscope pattern used in intro for The Outer Limits television series. I believe you're the person that could do a tutorial for this. Thanks😀

[@johnsmith56920]

A bit late but since you asked for it, I will say it. I would like to have a tutorial on how to make a curve deform modifier in Geometry Nodes. Also I'd like to know how I can use the Fresnel generated by the Shader editor into Geonodes (the idea is to use this to select the outline of the object as seen from camera-I know there is a way with the camera.normal dot product but Fresnel is such a beautiful map). I'll use this tutorial to generate lace. Thanks a bundle and congrats.

[@trochilusneon3141]

I came here directly from the video of Kris which for some reason didn't work for me, thank u so much for another really practical method for this! I'd really like to see a tut of making those non euclidiean stuff in your chanel, I think that would be really fun with your tech style! I've seen a bunch of them in indie games and always wonder how to make them by myself..

[@SymmetricVision]

Thank you for the work and thank you for sharing it. Wanted to let you know that the project available on your Gumroad doesn't work for me on two computers across Blender versions 4.0, 4.1 and 3.8. The moment I would open up the geonode tree for Cymatics the project would crash.

[@StrayCreations]

Hey thanks for your comment. I checked the file just now and it opens up fine for me in Blender 4.1. Have you tried opening the file with a clean install? It could be one of your addons causing the crash.

[@SymmetricVision]

@@StrayCreations Havent done it in clean install and will definitely look into addons because I am using a bunch. Thank you for making geonodes fun, I wanted to learn how to drive things with math forever. There are a lot of interesting things besides cymatics that I think youd be very able to do just because of this principle. I hope to understand it one day. Thank you so much for your work

[@StrayCreations]

Hope you can get it to work. I've seen your work before and curious to see how you'll use it! I'm still waiting for audio inputs for geonodes, that could make for some insane visualizers probably.

[@SymmetricVision]

@@StrayCreations oh nice, I had no clue you were aware of what I do, deeply flattering. I am curious about the audio inputs too but I try to not do anything automated even though just when I read your comment a bunch of crazy ideas exploded in my mind.

[@JesseJuup]

Very interesting and very impressive! 1. Can we input audio into X and Y? 2. How would we implement a Z so we get a 3D version of this?

[@StrayCreations]

Hi Jesse, I'm hard at work on implementing both of these features, the nodegroup already has some experimental features to introduce movement in the Z axis. The difficult part is that we can't import audio or a MIDI directly into blender and since Chladni patterns are based on frequency and not on amplitude, I'm not sure if it's possible at the moment. Of course you could hand animate the group to match the music.

[@雨冬陈]

love your tutorials,they are very clear and i can learn a lot!

[@StrayCreations]

Awesome! I'm happy to hear that :)

[@haiduongnguyen3277]

I have a question how this plot in the Mesh. After value calculated from function, then how it plot in the Mesh. It should get location of x,y and calcuated value. But how it can show in 2D. I really confuse here 😂.

[@patdimitri]

Thank you for this - I purchased your blend file on gumroad and always get super confused with shading when it comes to geometry nodes. IE - when I add a bunch of colors to the shader, it adds it to each individual point as opposed to the hole point cloud as a whole. Can you help me out?

[@sammedia3d]

OMG i was searching the entire internet for something like this! YA DA BEST.... you got my sub and of course a new GR customer lol. Just one question... how do i change the mesh or form of the particles itself to look more like a rock?

[@artofvibration]

Awesome

[@notimportantstudio]

yes yes yes so good my friend :)

[@nikaaduashvili4008]

I just started with Blender and had two problems when I was following your tutorial: 1) I can not see the node effect in the viewport 2) When I change Values the plane splits into 4 peaces

[@genesis2303]

How to get random index without repetitions? This is sth that get back to me from time to time, sometimes I can get around it with texture sth I don't. To get be more precise I want to scale text characters by random index one by one, random node gives me random index way that sometimes.. well most of the times it takes for example 2 or 3 characters at once and then one by one because those 2 or 3 characters have randomly get same index, and I don't want to search for lucky seed with longer phrases.

[@dennisvvugt]

@Stray Creations 4:13 how can i copy those nodes, and still connecting those wires, so that i don't have to reconect them?

[@frostDAirk]

You are a very smart guy!

[@pkay3399]

Well, thank you so much for posting it. I can use this video as a reference when I need it. Do you think Blender needs a rework of how to add mathematical equations (like DCTLs in DaVinci Resolve)? I mean, node-based workflows like any other type of workflows will get complex at some point, but something tells me adding expressions to the geometry nodes might need an update or two to prevent us from reaching that point too early in the development. Maybe I'm wrong.

[@StrayCreations]

Oh yeah Blender should definitely have a way to implement equations so you don't have to use a bunch of nodes. I can't wait until that day.

[@cleoingersoll2592]

This tutorial is extremely helpful! I was wondering if it would be possible to convert the form you have at 8:08 into an object that can be converted into an stl file? Im trying to extract the curves, before you used the geometry nodes to simulate smaller particles, to 3d print the cymatic forms. When I try realizing instances in the geometry nodes, as well as when I try to apply geometry nodes to a mesh, i'm encountering some errors where the nodes aren't able to be exported. Let me know if theres any way to do this :)

[@StrayCreations]

I'm glad it was helpful! Yes, you should be able to export any shape you make in geonodes by applying the geometry nodes modifier, this converts the objects from a geonodes group to an actual mesh. In the modifier menu there should be a little arrow which gives you the option to apply the modifier, or just F3 and search "apply modifiers". However, once exported the nodes are gone and you can't use the parameters anymore to change the shape, you're just left with a mesh object. (you might need to add a Realize Instances node at the very end if you are working with particles)

[@blackswan6386]

Hi sir, this is really amazing tutorial. i love it. can i ask a question ? After 5:21 i tried to make a material to have the white lines colorized, but with only " set material" node it dosent work, can you maybe help me on this ? would be cool if its colored instead of black and white, thanks sir. now subscribed - i just used the first math chlad node setup at 5:21 ^^

[@meirhuberman2552]

hi wandefool how do i shade it and render it ?

[@nikolajoskarlindblad9591]

Great tutorial and blender file! Do you happen to know a way to figure out how frequencies translate to m & n? Say I want to visualize a C4 (261.63Hz), how would I figure out which values are needed in m & n? Thank you very much, hoping your channel grows :) !

[@StrayCreations]

Thank you so much! I did my best to find an answer to your question. In real life, all objects, including Chladni plates, have a set of natural frequencies at which they vibrate. A system, such as standing waves in a musical instrument or in this case, a plate, tends to vibrate at certain discrete frequencies called natural frequencies or eigenfrequencies. As far as I know, the patterns are a result of the ratio between the introduced frequency and the eigenfrequency of the plate. So plates of different materials would display different patterns on the same introduced frequency. Since we are in software, we haven't determined an eigenfrequency of the plate, we just work directly with this ratio, which is the ratio between n and m. In short, at least according to my understanding: the pattern of a C4 depends on what the plate is made out of, so it doesn't look the same across all chladni plates.

[@nikolajoskarlindblad9591]

@@StrayCreations Thanks for giving such a well versed answer. That deepened my understanding to something I can work with! All the best to you!

great tutorial im trying to share it cause i feel that this content is under rated perfect for creativity im new to all this and im really trippin with the community behind blender keep goin i wasnt able to see the effect on cycles on the viewport tho and add texture apply only on the plane 😩

[@StrayCreations]

Hi there, thanks for your comment. I'll try my best to help out with anything that's not working. Are you using the right version of blender? (3.4+) and did you follow the tutorial or did you download the group?

[@trendyourdays7382]

@@StrayCreationsman thx for reply this fast your awesome 😁 actually im using version 3.4.1 and i did follow the tutorial, first i figured out how to put material pretty quick only had to add a set material node but the only issue now is that i cant see the effect in my render view port on cycles its showing me the plane only plz help i need this to work so bad 😩

[@StrayCreations]

I'm going to assume everything else worked and you were able to scatter points as discussed in the later chapters. Could it be that you've not instanced objects on your points? Throughout the later part of the tutorial we're working with "points". A "point" is just a position in space and not actual geometry. In the video at 19:00 I use an Instance On Points node to instance a UV sphere on the points. This turns the "invisible" points into actual geometry that can be rendered. As for adding a material: You could A. put your set material after the UV sphere node and before the Instance On Points node or B. create your own object, give it a material, and use an Object Info node -> select your object and connect that to the instance input of the Instance On Points node instead of the UV sphere node. I hope this works! Let me know if it doesn't and I'll try to help out the best I can.

[@trendyourdays7382]

@@StrayCreations yes i did put the instance on point and the uv sphere and it made it appear in the material view but i still can figure out why im not able to see the render im stuck with the plane i bet its a stupid error of mine like a bad node connection something like that im watching your video again and again to find my error

[@trendyourdays7382]

whats weird is that in render i can see the overlay of the pattern no texture no pattern mesh and the plane wont disappear

[@Markste-in]

your haircut is wild... i like it! nice tutorial too :P

[@rsher_digital-art]

Your brillant. Great tutorials. I request : A node group that builds human heads. Imagine using nodes to contour cheeks , eyes and smiles? A node group could translate imported date like mo capture of midi/wave files that drives for instance the cadece of eyes blinking, Lip syncing! EKG (brain wave) date to contour the heads expression.

[@StrayCreations]

Hi Richard, thank you so much! I would leave character creation up to a program that's already really good at it. The human face is one of the hardest things to replicate and make it look good. However, if you have an existing mesh with a rig you can do some pretty interesting things with drivers. Motion capture in Blender is a super interesting topic. My latest video was made using Motion Capture with a VR setup. I will make a video about it next week. I've wanted a MIDI node forever but it doesn't exist in geometry nodes yet. This would be so cool to use.

[@botina06]

Hello, amazing tutorial, thank you very much! Do you think it's possible to wrap the cymatics patterns around an object, like a sphere? How would you do it? Thanks again!

[@botina06]

In case someone needs a reply, I found a way that seems to work: during the creation of the very first geometry node, instead of adding a plane, add a sphere or a cube or whatever shape you need, and the patterns will appear following the shape of the object.

[@DanielGGava]

Hello ! I was to do this. Make the particles to follow specific shapes. I tried with a 3d shape, image texture and even wheight map ... no sucess. You were ablento do it then ?

[@botina06]

@@DanielGGava I managed to "wrap" the particles around a sphere by adding the shape I needed during the set up of the very first node, just like I described it on my previous answer. I believe this works with Blender's basic 3D shapes (spheres, cubes, etc.), but I guess that if you need to wrap the particles around a different shape to Blender's predetermined, my guess would be that you'd have to set up a node that is able to create / import said shape. and then connect it to the rest of the nodes.

[@DanielGGava]

@@botina06 thanks !

[@kuzwk]

you can consider to optimize this algorithm by removing unnecessarily division by one.

[@l1sten-zh6cv]

Is it possible to specify a logo or pattern like curve>mesh and then have the particles follow it?

[@StrayCreations]

Yes, you can use an image texture for this. Put the image through a color ramp in geonodes so that it appears black and white like the part at 7:00. Then follow the tutorial from there.

[@l1sten-zh6cv]

[@zenzenzen193]

Can't I make pattern by Hz?

[@StrayCreations]

In real life, all objects, including Chladni plates, have a set of natural frequencies at which they vibrate. A system, such as standing waves in a musical instrument or in this case, a plate, tends to vibrate at certain discrete frequencies called natural frequencies or eigenfrequencies. The patterns are a result of the ratio between the introduced frequency and the eigenfrequency of the plate. So plates of different materials would display different patterns on the same introduced frequency. Since we are in software, we haven't determined an eigenfrequency of the plate, we just work directly with this ratio, which is the ratio between n and m. In short: the pattern of a certain frequence in Hz depends on the material the plate is made out of, so it doesn't look the same across all chladni plates.
