secret sauce , same concept is with uv you can create nice water effect on image. instead of add use a displace , no noise threshold but the same over technique with level .03 opacity. i like the way you teach BRAVO!!!

@watsontao932 9 месяцев назад

Thanks for this amazing tutorial! For a smooth camera movement, you can first have the camera "look at" the GEO, then create a noise chop with two channels x and y, adjust the period and amplitude, then chop reference the x,y channel to your camera x, y translate and/or rotate, which you can further adjust by adding or multiplying after the reference. Hope this will help :D

@bananaliquorable 9 месяцев назад

SupermarketSallad! This is gorgeous, thank you so much for sharing. If still coming in handy -> I like to use an extra emtpy geo and a lookat to manipulate the camera. This way I can visually (with a donut in the 'empty' geo) put a focus for the camera, and move it around it by simply translating... No issue with rotation anymore. if it helps :)

@Mindspiritdesign 9 месяцев назад

From my experience, camera blend technique works best as u can sequence a series of cameras and then use LFO to animate between them.. Another technique is to use arcball camera, which is in the pallete. But for animating camera movements, camera blend is what I prefer.

@supermarketsallad 9 месяцев назад

Gotta try those things! I try to work with a fixed camera instead of trying to animate it. But these sound like some great approaches

Hi! First of all, great tutorial! Looking forward to more videos in the future! I have a question with the colors tho. In the pointfile select TOP when I want to change the x y z, I don't have red green and blue in the list. Is there any solution for this? Thank you in advance! ☺

@supermarketsallad 8 месяцев назад

Hmm, i get this question sometimes.. It means that the point-file you loaded doesn’t have r, g, b information. It only contains the position data. Did you use Scaniverse?

@caposta5141 8 месяцев назад

@@supermarketsallad oh I see, thank you for your fast reply! I have an android and sadly it doesn't have scaniverse. I tried Kiri Engine and it made a very nice and detailed pointcloud. Unfortunately then it doesn't have rgb info (but I have "nx" "ny" "nz" "s" and "t" on my list, I tried those but no luck)

@supermarketsallad 8 месяцев назад

@caposta5141 ah, those are probably normals (the orientation of the surface) don’t know what s and t are. Idk what s and t are. You can probably get some nice results without the color if it’s a nice pointcloud.

@PhaseDeRecherche 9 месяцев назад

Strange, I dont have the settings rgb in the node Point file select

@supermarketsallad 8 месяцев назад

It probably means that the .ply you loaded in doesn’t have that information.

@anzierfanwagner 4 месяца назад

Hi! I was wondering if there is a way to projection map the visual simulations onto the object that is initially used as the scan on Scaniverse? Hope that makes sense..

@anzierfanwagner 4 месяца назад

Also can you specify how to make this audio reactive with sound design implemented?

@Vibe_Collector Месяц назад

Is it possible to get similar results with a 3D mesh designed in blender? I know blender exports PLY but I noticed that the RGB drop downs were different with the point file TOP when I tried it. So the tutorial didn't really line up fully.

@supermarketsallad 6 месяцев назад

So you kinda need to drag from the last sop and then press tab to open the menu, and then it has a sop in. Or you can go inside the geo and put down an “in sop,” delete the torus, and turn on the display flag in there

@8eck 8 месяцев назад

6:30 the coolest part. But now you can do the same thing with 3D gaussian splatting. Btw what is that software?

@supermarketsallad 8 месяцев назад

thanks, this is Touchdesigner, a program mainly used to make interactive real-time performances etc. but it's very versatile. I haven't worked with Gaussian Splatting.. I guess you could produce similar results, but I don't know what if you can manipulate that data like this.

@mattnykamp 8 месяцев назад

how would you / could attach an audio file as input? The idea would be to make the pointclouds interact with the audio file, but I have no clue how to do that lol

@supermarketsallad 8 месяцев назад

The answer is yes, definitely. But the margins of this RU-vid comment is too small to describe how to do it. My guess is that you don’t want to use the audio as pointdata, but that you are interested in making the point manipulations audio-reactive. There are a lot of great audio-reactivity tutorials on RU-vid by elekktronaut and acrylicode among many other. I also have one on my channel. That could get you started in how begin.

@mastoiloicos253 2 месяца назад

If I change the .ply file for a different one the Geometry Node has this Error: All OPs must generate the same number of instances (have the same lengths). Is there a way to change just the file and that it keeps working?

@supermarketsallad 2 месяца назад

Probably the easiest way to fix that is to press 1 on your keyboard to reset the feedback loop. And make sure you are using the same point file for color and position.

@TheAndreyMak 8 месяцев назад

Great lesson! Is it possible to use other formats, for example video instead of .ply?

@supermarketsallad 8 месяцев назад

Pointclouds come in different formats. But a video wouldn’t work for a few reasons. Mainly because it doesn’t have point information.

@robrob2835 5 месяцев назад

@Nanotopia 9 месяцев назад

I am wondering why my plys don't give the lines like yours- any idea? I've tried with a couple different plys and messed with settings, copied your settings etc. and no wavy growing lines.

@supermarketsallad 9 месяцев назад

The lines come from the feedback loop combined with the texture 3d TOP. If you follow the tutorial, and play with the noise and threshold, something that looks like this should appear. you can check out the tutorial I linked in the description to understand what’s going on.

@Nanotopia 9 месяцев назад

yes yes- I have done this no problem it is just that my plys do not stretch they explode 😂 which is nice but the lines are amazing @@supermarketsallad

@miliv_eth 8 месяцев назад

I had the same issue for the wavy lines being not present. The solution Ive come across was setting the Offset property of the Noise inside the feedback loop to 0. Hope it helps! m

@kno1541 6 месяцев назад

DOPE MAN, do u think that i can do the same effect but with a video instead of a 3d object?

@supermarketsallad 6 месяцев назад

Thanks! No, not really. A video doesn’t contain 3d info. You could use it as a color map for a 2 or 3d particle system using similar techniques to this. But it’s quite different from this. My tutorial “fire-iris” creates a 2d particle system if you are interested.

@supermarketsallad 9 месяцев назад

I actually don’t know, it sounds like you are correct. It looks like polycam can export plys. Otherwise, when doing the transformation check to see if there’s a color option. But I actually don’t know what I’m talking about here.

@mrshinesun Месяц назад

Great Tutorial! Like many, I could not change the X Y Z values to Red Green Blue in my PointSelect. What worked for me was using a GLSL top instead, with the follozing code: out vec4 fragColor; void main() { // Fetch the color from the input texture, where X, Y, Z are stored in R, G, B vec4 xyzData = texture(sTD2DInputs[0], vUV.st); // Assuming the range of XYZ values is from 0 to 1 // Here we directly map XYZ to RGB fragColor = vec4(xyzData.r, xyzData.g, xyzData.b, 1.0); // Set alpha to 1 for full opacity }

@supermarketsallad Месяц назад

Hello! This is a neat idea if you want the points colored according to position. This is however a little bit of a walk around the block to end up at your door, and you could actually bypass this node and have the same result. If you don’t have an r, g, b buffer in your point file select that could mean one of two things. Your pointfile doesn’t have color. Or it has color but they are labled as something else (in that case I suggest trying the different buffers to see which ones are the colors)

@giulialuotto9466 5 месяцев назад

hi! idiot noobie here. i followed the teaching (great work btw) up to the basic manipulation but the threshold + noise just dont? work? does anyone have any idea how to solve this?

@supermarketsallad 5 месяцев назад

hello noobie. Maybe you forgot to close the feedback loop.. Or maybe you didnt set it to input*noise in under “output” in the noise. Maybe you didn’t turn up the soften enough in the threshold. Or maybe your pointcloud is really large or really small.
