Image Instancing - TouchDesigner Tutorial 26

In this TouchDesigner tutorial we convert a 2D texture into 3D geometry using TOP instancing. We also create a reaction diffusion sketch as an example.

Amazing! Your tutorials are so good! All the steps are very well explained and there's space for further suggestions and creative experiments within the project! Much

[@rayxctf]

Man! this is super useful! Thanks a lot and wish you all well!

[@cheetahlion79]

This is one of my favorite tutorials of yours I've seen. I can't wait to try.

[@cheetahlion79]

For some reason, when I change the cam viewer to active and try to rotate the image, it keeps moving back to the same position. So I can't see the grid like pattern. Hm. I'll keep messing with it.

[@MultiMam12345]

you got me hooked on learning touch designer. Awesome tutorials. Easy to follow. I found this clip on particle instancing on youtube. Just do a search, which would be a great tutorial. Maybe you already did that, but its a great clip which goes toofast to follow. Thank you!

Amazing tutorials! I am studying by watching your tutorial. I want to display the numerical value currently reacting in real time on the screen being rendered. What should I do? And I want to place the text where I want it.

[@ahmadmoussa3771]

Hey man, thanks so much for the amazing tutorials! I've been recently discussing touchdesigner and glsl shaders with some friends, and I wondered, what do you think are some differences between the two, and what's some stuff that can't be achieved with touchdesigner that you can do with shaders, and vice-versa?

[@elekktronaut]

You're very welcome! GLSL is a lot more powerful I'd say and when it comes to vertex shaders (so 3D transformation/manipulation), GLSL can do much more than TD. In the realm of pixel shaders I think TD can do just as much as GLSL, it's just about finding out how. GLSL is great if you're a programmer but for people like me (artists, designers, musicians) it's super hard to get into. Hope this helps!

[@SeppMessner]

Hey, I have a Problem at min 14:50. Somehow after connecting the NULL (called col) to the "Instance 2" and after inserting r,g,b,a.... GEO shows an ERROR with "All Ops must generate the same number of instances (have the same length)." I think I did everything the same so far. maybe you could help me out, please. Thanks so much for ALL your videos. very sympathetic and amazingly useful! greets

[@CapitanKilpack]

as always, what an amazing tutorial! i'm having a little problem: when i try to instance the "color null" on the geo, it goes full black, and an error shows up saying "All ops must generate the same number of instances (have the same length)". any idea on how i can fix this? thx in advance!

[@cfeaugas]

What "length" means in this context depends on what kind of op you are using for the instancing: For CHOPs, length = number of samples. For TOPs, length = number of pixels. For SOPs, length = number of points. You can see an op's length by middle-clicking on it, or by pressing the info button on its parameters page. Basically, if you were only using TOPs to do your instancing (as in this example), you need to make sure they all have the same number of pixels, that is, the same resolution. Note that this requirement applies only to the ops being used as the instance ops, not to the geometry itself, its source SOP, nor the render. Hope this helps.

[@elekktronaut]

Exactly. This is why we're using a Constant CHOP here to set the resolution so it's the same for all maps. If it still shows the error, click the cross on the geo twice, that should fix it.

[@CapitanKilpack]

@@elekktronaut @cfeaugas thank you so much to both of you! i dragged the resolution from the Constant CHOP and pasted as reference on all of the maths and it works just fine. again, thank you for the quick response and for helping me out, i love this community ♥

[@luisricardogutierrezmaya2603]

Maybe you dont need this answer anymore but... in my case was because i forget to use the constant resolution on the ramps, you will need to select the null box of constant (second operation you use on the video), and drag it to resolution and select "Chop reference" im not a profesional using it but 15 minutes of underestanding get it working XD

[@bondell1840]

can we use a camera realtime for this?

[@peri_171]

fucking good bro, thanks.

[@monikabronowicz7272]

Heyy there! Basic question but I have an issue with changing my whole view from square to rectangle. I tried to play with resolution of different operators but I can't make this work. Bileam and everybody, anny suggestions which operator should I manipulate? Thanks in advance!! :3

[@Taylor-op8tv]

I'm curious, what GPU are you using?

[@artao5]

Holy shitballs this is awesome!! Nice work. How have I been ignorant of this software for so long? I only just discovered it today, and I've studied CGI for over 25 yrs. ..... I guess I only started getting into video and visualization over the last year or two tho. This is EXACTLY the sort of software I've been looking for. I already spent a couple hours with it after watching only a couple basic usage videos and came up with some darn tootin cool stuff. Pricey tho. How often do they have sales?

[@elekktronaut]

I felt the same when I discovered touch :) Yea it's a bit expensive and they barely ever have sales but as soon as you're using it for commercial work, it's quite alright. Also, the free version is great!

[@LoveYujinLoveIVE]

Thanks for the tutorial~ But i have a issue on 14:42, when i change the colour rgba in GEO, it doesn‘t work, would you help me to solve this issue? thank you so much and happy new year~

[@mofeeddaghoum4230]

Did you figure this out?

[@SJF_tokyo]

Hi Bileam, this video is amazing thank you but I'm having an issue at 14:45 when you drag the col TOP to the Instance 2 page of geo. As soon as I do that the image turns black and I can't see anything. If I remove the word 'col' from the Color OP box and enter 'r g b' like you've done I can see a colored version of the image but not the same colors as the image itself. Do you know what might be wrong here? I thought I followed exactly but I think maybe I missed something :/

[@fovkotov]

the same problem that you have

[@dabeat2006]

kinda of the same problem. When I enter R G B A to instance 2, it turns black

[@a.f.m.4134]

Bileam, this is a basic question but how do you move the camera from within the operator so smoothly? as soon as I click it and move it with my mouse it moves way too much and totally loses the frame.

[@elekktronaut]

Hmm maybe press 'h' once your operator is active and then try moving around with LM, MM and RM (mouse)

[@ellespencer-lewis1015]

I don't know why, but this is not working for me. All I get on the box is a representation of red blue green and alpha in a grid on the box. It's raised but very wireframe-y. I think the new versions of Touch have changed something such that this tutorial no longer applies? I'd love any insight into how to make this work!!

[@banninhaideri3771]

Hi Bileam, great tutorials but I'm facing some issues T 19:43 when you give values to displace, you get to see black n white movement of random shapes. mine does not show anything apart from blank black screen. I tried to play around with values but couldn't fix it. Can you help me figure this out?

[@faithu4]

I had the same issue!

[@makouillegauche]

@@faithu4 Did you find a solution you could share with us ?

[@michelleWalter-jm9hm]

would be interested in this as well... watched the tutorial several times, couldn't find the mistake. I gues it has something to do with the composite, and substract operator, because after that there is nothing moving anymore..

[@CapitanKilpack]

i wonder if there's a way to make this audioreactive, is it possible?

[@elekktronaut]

You can make pretty much anything audio reactive in td. An easy to do this here would be to convert the audio spectrum into TOPs and composite that into the map :)

[@sandrokann9054]

Hi dudez, this Is a very interesting tutorial but I have the previous version of TD and I can't download that cause my computer Is too old. So, if you can help me I really appreciate. I have some problem with the top instances, for the reason I told you before. So, I try to use the "TOPto' but does'n work for the geo. I creat a grid whit comp and use the top and again the comp for the instances, how you explain but Sorry me in this way I dont now how I can use my videoin for the geo... Thank you a lot. Bless

[@elekktronaut]

Hey! Without the current version of TouchDesignerr this is a lot harder to achieve. Check out Noto The Talking Ball's video (kzbin.info/www/bejne/iXu9eoB9nJKnnrs) which might help because he's converting the data into CHOPs.
