coincidences

Last night i was developing a patch, kind of open gl feedback with glitch and geometrical transformation. I was able to produce some really ok results, like this.

After a while, i put some pictures to my flicker account and i got a comment from Rosa Menkman, not just a comment, an answer:

the first is my picture, the second is Rosa’s one:

Thats funny, we are working with really different technics, but somehow, we have crosspoints.

I spent 3 days together with Rosa in Lithuania, and we made a short workshop, we saw each other works, and finally we made a special ‘vj-set’ together. She’s stuff is more then great, her solo set was for me hours of watching and watching.

I hope we will collaborate more in the near future.

+ imortant links:

1. A vernacular of file formats: very important guide to the file formats, for those who are using Quartz Composer, i would suggest to use with Vade’s Glitch File Reader. We tried already, and its awesome.

2. Glitch Studies Manifest: no comment, its impossible to skip.

Video Noizz-a very useless tutorial

Its not a normal tutorial, not producing any usefull thing and maybe sometimes the result is unexpected, but a good basic feeback video noizz, from PXN.

I normally check my blog daily, and  i can see whitch was the search engine terms what the people used to find my site. In the last time i found this one: quartz composer video noise generator, 3 or 4 times. So i decided to share my solution here.

We are going to use a feedback, some special blend modes, and over-adjusted opacity, and basicaly thats it.

The only one special plugin what we need is the kineme GL tools, its a free collection of very handy  plugins for QC (10.5,10.6). You can donwload from the kieneme site.

After playing  bit with the new plugins, we have to search for Kineme GL Logic Op. Its a macro patch so will render out what is inside in the macro patch. But as a blend mode it needs something under, i mean an under layer, so we have to make a bit more complex thing.

We place a sprite (with the right size) in the Logic op and the logic op in a render in image. We put another sprite inside in the render in image as well, this will be the under layer as i mentioned earlier, and of course a clear under. So this is the render in image.

The next step should be to publish all the two sprites image input (the one in the kineme GL op mode and the other in render in image). So both has to be published outside render in image. And a practical thing to publish the input of ‘gl op mode’ (the mode one).

Now we need some other nodes as Core Image Accumulator (as the grandmaster of feedback), ClOpacity (to control the feedback), and an image Texturing Properties (to transform a bit the feedback). And a sprite at the end, and of course a video source (i used video input).

Lets make the connections. And its done, well the test blendmode can be ‘Xor’. Noizzee, but what about some nice lines, instead of noizz. Thats why we need the ImageTexturinProperties, for example lets put the ‘MatrixTranslationX’ value of the Image Texturin Properties, higher then one. We can play with the scaling values and with the rotation as well.

Final adjustment:

If the result is to much flashy, then we can get back a bit, switching ON the ‘Disable Color correction’ option of the ‘render in image’ (alt+2).

Lets play with the opacity, blendmodes and maybe some more nodes we can connect to the output of the ‘core image accumulator’ , but thats easy to try.

I tested this composition as an effect in VDMX and works perfectly, the speed is really ok, and i used last weekend during my performance at the Satta Outside festival. I will write the festival review soon.

meanatime i wrote this tutorial i got this random QC interface glitch, so i will share it. Dont ask how:)

pxn is going to lithuania

Iam invited to play a 3 hour long vj set at Satta Outside festival  in Šventoji, Lithuania. This year the thematic is glitch, so i will make a dedicated pxn set. I decided to use this time VDMX, so iam trying to involve all my pxn fragments, as effects and as generators. The other ‘thematically’ invited artist is Rosa Menkman.

here is a small preview directly from vdmx:

dis-play 10

I played a 30 minutes A/V performance with LOD during the dis-play festival at the cervantes institute Berlin.

It was a real improvisation, we didnt met before, but worked well.

I made a custom patch for the performance with some of my classic generative thing and with some new one, but for the first time i used ‘PXN‘ as an effect unit for this kind of minimalistic-generative content.

The pure QC patch (no vdmx this time) gave me really high resolution and minimum 25fps.

For the PXN effect unit i used the ‘read pixel’ from Kineme GL tools. Really fast and no bug at all (this time after several dark minutes i switched back to leopard for this performance).

for control i used iphone with a custom TouchOSC layout (made for this patch), and my wii controller for the WIP. This time i used mostly Datamosh for the WIP draws.

It was real fun, good music and really nice audience.

Installation with nuts

Recently i made a small installation for the ‘Lange Nacht der Wissenschaften’ (lets call it as the long night of the sciences), at Collegium Hungaricum Berlin.

This year the symbol was the nut, or a half nut.  That form is really similar as the organic structure of the human brain.

For the nuts i designed a neuron like system. It was more then 300 pieces painted to white, so the lines working well on the nuts surface.

For the neuron surface i used a very simple spline structure, programmed and mapped in Quartz Composer.

For the brain picture, i used the Dicom plugin for quartz composer with a one of the sample file.

More infos about that night you can read here.

pxn more and more

The festival coming really soon, so doing more and more ‘pxn’ stuff.

here+now

pixelnoizz, *spark, an empty media card and a glitch machine:

when its here+now, you’ll be part of it. an experimental performance workshopped as part of visualberlin festival 2010.

this will be the first time, i will use my ‘PXN‘ package, and it fits in the original concept.

so what is this ‘PXN’ thing?

This is a set of plugins, effects, transitions and generators. Based on really easy transformation of glitch, feedback, blend and mask-modes. And of course my G_P_G  is a decent part of it.

The basic concept was to make very easy performance without many contents, perhaps a live camera feed in to my face or just one video loop. And using 30-40 filters and combining them with blend-modes and feedback. I think this kind of combination is enough for a performance, and the performance will not less than one performance with hundreds of well prepared video loops.

And yes, we met with *spark during last LPM festival, we spent some time together and with Vade as well. He offered to make something with a wireless photo camera and glitches. As my stuff is really supported by Vade’s V002 its in reality a cooperation between us.

newzz

Here is a video from the latest project, the exhibition what i curated in dortmund. This is the same balaton exhibition, presented first time in berlin. Now its working like a ‘travelling’ exhibition, will be presented in Balatonfüred, Cottbus, Mainz, Budapest and ….

The Visual Berlin festival is very close, so i have a decent organization issue with the workshops.

NI-GLE Curved Tube

GLE Curved Tube is a bezier curved tube with control points and many-many parameters. Easy to use, working well with iteration. I just made a quick test, but iam pretty sure  that i have more rounds with this niceness.

the per pixel lighting  mode let you emulate the lighting, just need to drop in a lighting patch and viola.

NI aka Noise Industries providing the FxFactory, mostly QC based filters for commercial video editor and motion graphic software .

This one is also sweet:

*this is not a commercial, just i like the tool:) thanks Vade for the info.

workshop examples

uploaded two examples from my b-seite workshop. The title should be: introduction to the structures. And  the javascript patch from toneburst.
