Understanding this points-based technique

Hi all,
First thing first apologies for the title of this thread but I didn’t find a better one.

I was scrolling TD posts for inspiration and I found this one: tokamu on Instagram: "Undream - - - #visualartist #digitalartist #touchdesigner #electronicmusic #glitchart #3dartist #eurorack #tokamu #abstraction #digitalabstract #motiongraphics #motiondesign #technomusic #audiovisualart #pixelart #installationart #generative #vj #artxdesign #abstract"

To me, it is fascinating the way the images (or geos?) literally dissolve in a cloud of points, or something very similar to this. I was wondering whether someone could explain to me how to achieve such an effect. I thought of PointClouds, but seems not the answer in this case.

I thought it was something achievable only by using glsl code, which is why I’m investigating that atm, but (at least judging by the tags accompanying the clip) the artist didn’t use it.

Thanks to anyone who will help and enlight me

Hi @cimmi,

first I would recommend asking the maker if they want to reveal the techniques used in their creations.

Next I would recommend learning everything about instancing and playing with the available operators. You would be surprised how many things out there are done without a single line of glsl.

Have for example a look at our InSession with Matthew Biederman - we are discussing a few techniques that could be utilized.

Hi @snaut ,

Thank you very much for pointing me to that talk, I started watching it and is enlightening so far.

Concerning instancing, I was experimenting with that to obtain a similar effect, but it was killing my computer, so I thought it was not the right way—but perhaps it was only me doing thing wrongly?

Definitely I’ll try to contact the artist.

Thanks again

Hi @cimmi,

there is a 3 part series here on pointclouds as well. It’s a bit old but most things should hold up true.

cheers

I’m not an expert on the topic, but it looks heavily feedback-based to me. Have you experimented much with the Feedback TOP?

thanks a lot whoisbma. I did some experiments with feedback indeed, but the amazing characteristic of TD (which is also a course, to me) is that is so open that (i) can never say “I’ve explored enough of it”. So yeah, i tried to play with feedback technique, but the possibilities are endless and surely, if that effect was realised thought feedback, i didn’t find yet the right combination
