Participants use free or open-source 3D scanning apps and software (which they can access online) to scan reflective, invisible, specular, refractive, or ‘ephemeral’ objects and materials to create images that actively confuse the imaging algorithm. Audiovisual creation in Pure Data/GEM using [ARRAST_VJ] – Bruno Rohde 10am-1pm - online(BBB1) https://21.piksel.no/2021/11/19/audiovisual-creation-in-pure-data-gem-using… This workshop introduces the basic and creative uses of **[ARRAST_VJ]**, a free software for audiovisual creation that enables real time manipulation of videoclips (with sound), images and cameras, and also the creation of interactive compositions, which may be stored, reproduced and exported. SATURDAY 19th NOVEMBER A Butterfly in an Analog Computer – Wolfgang Spahn 11am-1pm - Studio 207 https://21.piksel.no/2021/11/20/a-butterfly-in-an-analog-computer/ Generating chaotic signals, noise and sound with an analogue computer and Chua circuit, learning the basic functions of an analogue computer along the way.

In general, participants should have some basic experience with a programming language, knowing how sound synthesis works in SuperCollider is advantageous but not mandatory. Simple WebXR with AR.js and Model-Viewer – tacacocodin 11am-12:30pm - online (BBB2) https://21.piksel.no/2021/11/19/audiovisual-creation-in-pure-data-gem-using… Covering the basic and recommended settings for having simple AR web applications. In this case, Modelviewer for using Android's ARCore and iOS's ARKit native frameworks and AR.js for simple marker tracking. Jeu Videa – Natacha Roussel/Amelie Dumont 12.30pm-2pm - online (BBB2) https://21.piksel.no/2021/11/20/jeu-videa/ Exploring collectively, feminist and intersectional possibilities of vide-a game by learning Godot Engine software. Since the episode of “Gamergate” a few years ago, and partly thanks to the work of feminist academics such as: Anita Sarkeesian (feminist frequency), among others, we now have a better understanding of gender relations in video games. So far there is still very few attempts to develop a video game format that captures feminist and collaborative principles, by transforming the modalities of video games.

GUI freezes on windows?
by Peter P. 17 Nov '21

17 Nov '21

Hi, a colleague of mine has frequent freezes of a recent Pd's gui on her Windows computer. It's of the type where depressed message boxes retain their thicker/darker box border. Audio continues to work, the patch can still be saved but no longer interacted with graphically using mouse and keyboard. Is such a behavior known? Thanks! P

With this update now the object also works on macOS :) With [websocketserver] you can send/receive to web-browsers via websockets. There's an html example in the help patch. Javascript knowledge is needed to interface the web-browser. It's up on Deken (for Linux/macOS/Windows). Please report issues to https://github.com/Lucarda/pd-websocketserver/issues :) -- Mensaje telepatico asistido por maquinas. _______________________________________________ Pd-announce mailing list Pd-announce(a)lists.iem.at https://lists.puredata.info/listinfo/pd-announce

pd~ crash with broken pipe and difference between "pd~ start -nogui" and pd~ with gui
by cyrille henry 15 Nov '21

15 Nov '21

hello, I've got some problem with pd~. I'm using pd 0.51.4 and pd~ version 0.54. It look like pd~ scheduling have been changed from what I was used to. now, pd~ with or without gui did not react on the same way. And I also experience crash with "broken pipe" error in various situation. See attachment for better explanations. Can someone please confirm this problem? What is the best practice using pd~? The only solution I found is to have a [loadbang] -> [dsp 1( -> [send pd] in the main patch and in the subprocess patch. This way, things works the same if pd~ is started with or without gui. cheers Cyrille

makefilename multiple substitutions
by Max 15 Nov '21

15 Nov '21

hi list, The helpfile for makefilename has a subpatch "multiple substitutions" in which it says: You can connect two or more objects for multiple substitutions. For that, you need to use a literal '%' to set the format string of another makefilename object. LITERAL %: You can format a string with a literal '%' if you escape it with another '%' (where "%%" becomes "%", "%%%%" becomes "%%" and so on) however, just a depth of two substitutions is in the example. I extended this to three and got the error: makefilename: invalid format string '%%%02d:%%02d:%02d' (too many format specifiers) (Yes you guessed right, trying to generate SMPTE from milliseconds) M.

I cannot reproduce the behavior now, either. Very mysterious. > I’m on Catalina (10.15.7). My patches seem to load mostly correctly, but one thing I notice immediately is that any object that flashes when you click it, like buttons or message boxes, stay stuck in the ‘flash’ color when clicked. for what it is worth, i do *not* see this behaviour on Catalina (10.15.1): both [bang( and [bng] flash and get back to normal. gfsdmr IOhannes

Re: [PD] Pd-0.52-0 macOS universal build (prerelease)

Hi Dan, This is very much appreciated! I’m on Catalina (10.15.7). My patches seem to load mostly correctly, but one thing I notice immediately is that any object that flashes when you click it, like buttons or message boxes, stay stuck in the ‘flash’ color when clicked. I’m also getting this error, which doesn’t happen with Pd 0.51.4: soundfiler read: ~/Documents/PD/PD_Patches/Scales/11-31.scl.tab: unknown header format I haven’t gotten as far as making sound yet, perhaps due to this error. Thank you for your work on this. Best, Phil Stone Davis, CA

Can you send a copy of the file and maybe a patch that simply loads it into the table? > On Nov 11, 2021, at 12:09 AM, Philip Stone <pkstone(a)ucdavis.edu> wrote: > > It’s a text file, loaded using [read -ascii -resize $1 TUNING_TAB] passed to soundfiler. Pretty old code, so there’s probably a better way of handling it, but I only noticed it because it broke. > > Pd 0.52-0 includes the sound file handling update I did which overhauled a number of things and added support for full AIFF headers and CAF files. The file type can't be detected from the file extension, so it tries to figure out from the header bytes but failed with the error. > > Thanks, Dan. I’ll get more chance to test later. -------- Dan Wilcox @danomatika <http://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>
