just the most basic aspects of a fluid sim.
Inspired by this TOX. by Joseph Peltz, check it out for some advection and clever use of the reorder TOP.

Reminds me of the last Radiohead album artwork. Super slick tho 👌 Looking forward to your other videos

@Julesloup_ 3 месяца назад

Awesome, I really love your work! Btw I got some issues with my feedback that won't loop & my particles are fading away after a certain amount of time. Any clue to resolve this ? Thank you !

@cloudlesssnowstudios633 8 дней назад

hello, is there a way to change it into two colors? Like Blue and Red?

@crismatygo 3 месяца назад

Great video! I'm currently experimenting with this. I'm curious, is it plausible to import a 3D model into TD and have the particles interact with it like in the video?

@supermarketsallad 3 месяца назад

This particular technique is only possible in 2d, but the concept (measuring density and dispersing) should work in 3d

@THIEFSOUNDS 3 месяца назад

incredible. is there a way to have a an image or keyed-video in the background that the fluid reacts with? like it does with your mouse.

@supermarketsallad 3 месяца назад

Probably, try the optical flow component :)

@faericake 2 месяца назад

have you figured out how to achieve this? i'm wondering the same thing (:

@MarsAttack23 Месяц назад

Can I make it audio reactive?😊

@atakankzltan1121 3 месяца назад

Thank you for tutorial. If I change resolutions as 960x1280 or any vertical res, it does not work. I think it is about "add and convert" but I could not solve that. Could you please share with us what we have to do for vertical works? Thank you!

@supermarketsallad 3 месяца назад

hello! It's actually a little trickier than that. My honest sugestion is cropping the output with a fit top. You could also do some math before the remaps. so you are changing the range to the aspect ratio so in 960x1280 the red channel is changed from range 0. - 0.75 to range 0. - 1. and this goes before the second input of the remap. But there is some more changes that will need to be made... So i just suggest cropping it.

@@supermarketsallad WOW! That's why all of us love you! Thank you for your detailed response. I didn't try yet your suggestions but logically it will work. Thank you.

@zaurshukurov4426 3 месяца назад

Is it possible to slow down the spinning?

@supermarketsallad 3 месяца назад

increase the blur-size, slower the slope-strength, lower the "degrees of turn" in the point-transform, or add a math after the pointtranform and multiply it by a number < 1. are some suggestions :)

@letgoletgo 3 месяца назад

Love your tutorials! I have a weird problem. Add sop doesn't add a point, any clue why does that happen ?

@letgoletgo 3 месяца назад

had to make a point using a 1x1 resolution noise top, then converting that to chop then sop :X

@supermarketsallad 3 месяца назад

Oh no, that’s really odd. I have no idea

@supermarketsallad 3 месяца назад

did you toggle the "add points" in the add sop?

@letgoletgo 3 месяца назад

yeah. I updated to latest version and now it works. No clue why it didn't.

@thenodeinstitute Месяц назад

Following this tutorial, as one of my students wants to use it with a differen aspect ratio of the render. While the result is beautiful and of course i appreciate the effort, i must say, that like many Tutorials, it is missing an explanation, why certain operators are used and what is their function in the feedback loop, making it very hard to understand what is going on and thus learning from it. Why not add a bit of explanation what each of the emelents do? As teachers we see this a lot. Student copying tutorials but not being able to modifiy them, as it is pretty opaque WHY things are being done/happening. It's know as the "tutorial problem" in academia ; ) Not complaining, just trying to inspire, thank you for your work!

@supermarketsallad Месяц назад

on one hand, I agree. I've started adding descriptive annotations in the tuts, and I will do that more in the future, to be clear how and why I do things. On the other hand, I don't necessarily see my role as an educator. These are "come paint with me" tutorials, like Bob Ross videos. I'm an artist sharing my process in a business that tends to be pretty obfuscating about that stuff, and I believe in transparency. On the third(?) hand, I realize that there are students watching, and that kinda scares me, but I have a responsibility to explain what and how. Thanks for your input I really appreciate it. (regarding aspect ratio, I gave some pointers in another comment under this video, but it is pretty involved. You (or your student) can reach out to me, for example on IG, and I can walk you through it)

@thenodeinstitute Месяц назад

@@supermarketsallad Thankl you for that generous offer! i will let my student know : ) I understand you artist argument of course, you have no obligation at all. But I feel it is not soo much more work to say a sentence about what the slopes or blurs achieve in that setup, if you know for yourself and it will help the community, (as many people refer to your tutorials) to be smarter ; )

@supermarketsallad Месяц назад

@@thenodeinstitute totally agree, working on implementing more explanatory content. :)

7:34 what was the shortcut for ''Resimulate or re-cook idk''. My simulation stuck at some odd visuals

@supermarketsallad 2 месяца назад

At 3:18 we put down a keyboard in chop that resets the feedback. So it’s whatever you assign that CHOP to. Probably the 1 key on your keyboard, if you haven’t customized it.

@VeraArt-wt4nl 2 месяца назад

@@supermarketsallad Oh i see. Thats my first tutorial cant reach the same results while following the tutorial. Is that normal?

@supermarketsallad 2 месяца назад

@VeraArt-wt4nl it’s probably a pretty difficult tutorial to follow as your first, since I don’t spend much time “teaching the program.” But it should look relatively similar, and if it doesn’t, maybe you still make something cool and learn stuff. No time spent trying is wasted time.
