GEM: borderless window is also always on top (and hasn't an icon)
by Matteo Sisti Sette 01 Aug '11

01 Aug '11

Hi, In ubuntu, if I send "border 0" to [gemwin], then the window (once created), besides being borderless which is the expected part, also sticks on top and doesn't have a button in the panel on the bottom of the screen as windows usually have. Not so in Windows, where it just creates a borderless window which, a part being borderless, behaves as any other window. Is there a way in Linux to get a gem window that is simply borderless without sticking on top and without having to renounce to the panel button?? thanks m.

[gemdead]
by Mathieu Bouchard 23 May '11

23 May '11

from irc #dataflow : <hellocatfood> Is it possible to use [gemdead] with objects such as [cube] and [sphere] in gridflow? In theory, I said no, but actually, [gemdead] doesn't prevent you from using OpenGL elements, and things like [cube] and [sphere] don't check at all whether they're given a real [gemhead] context, and don't seem to be doing much that is related to it, therefore : [gemhead] | [b] | [gemdead] | [cube] will really draw the cube as if you had done : [gemhead] | [cube] I suspect that very few Gem object classes really depend on an authentic GemState (one that was really created by [gemwin]). When you do find exceptions, please tell me. But you may have to use [gemhead] anyway (as in the above example) as long as [gemwin] decides when to clear the buffer and when to copy the buffer to the screen, just because [gemwin] uses [gemdead] to say when it's the time to draw. _______________________________________________________________________ | Mathieu Bouchard ---- tél: +1.514.383.3801 ---- Villeray, Montréal, QC

Extended View Toolkit
by news＠petervenus.de 21 May '11

21 May '11

Hello All! I want to announce the official release of the Extended View Toolkit. http://puredata.info/Members/Weitsicht/extended-view-toolkit/ The Extended View Toolkit is a set of abstractions developed for the art installation "Extended View streamed". It is intended to be an easy solution to experiment and realise panoramic video and complex multiscreen projection environments to createimmersive media experiences. It features a set of abstractions that are able to combine multiple related image-sources (like video input, video playback) into aconsistent panoramic image. The source-material, e.g. the camera to display has to be aligned horicontally, since image-combination is based on simple, openGL basededge-blending and not algorithmic pix by pixel comparison. Furthermore it features abstractions to create multi-screen, multi-projector environments to enable correct representation of (not only)panoramic material. The projection abstractions can be combined to form big screens out of multiple projectors with softedge betweenoverlapping borders of single projectors and contain a vertex model that can be adjusted in 4, respectively 9 points, so that projections onchallenging geometric surfaces is possible. Additionally, all abstractions are controllable via OSC-styled send/receive-messages, which simplifies OSC-based external control. Also, since streaming video was part of the project, a gstreamer based streaming solution was developed by Peter Innerhofer to distribute panoramic/multistream video over network. It can be found here: [https://github.com/peonic/streaming] Libraries needed: mrpeachBuilt with pd 42.6 and GEM 92.3 Credits: Shader Programming/openGL: Cyrille Henry GEM: Marian Weger Prototyping/GEM: Peter Venus Streaming: Peter Innerhofer Initiation/Supervision: Winfried Ritsch A short demo-clip can be found here: [http://vimeo.com/20311051] The project was made possible through support from IEM-Institute for Electronic Music and Acoustics (iem.at) and CO-ME-DI-A. The CO-ME-DI-A project is supported by the Education, Audiovisual & Culture Executive Agency (EACEA) of the European Comission forthe period 2007 - 2010 ([http://www.comedia.eu.org/]). Your feedback is welcome! Peter

new Pd Tutorial in English
by Alexandre Porres 16 May '11

16 May '11

Hi folks, what's up? This all started with my pd classes in portuguese in Brazil, I then developed this tutorial that got kinda big. I'd show it to international friends around and they seemed interested, some told me about having a spanish version or french but I could only do it in english. For an workshop in Piksel last year I tried to translate it to english, could only finish it now. It's nice that it forced me to rewrite the whole thing (so I must have generated a whole new bunch set of errors) and now I have an old Pd tutorial in portuguese that I don't like anymore, I should rewrite it to portuguese now (maybe next year as I wasn't aware of all the hassle it is). I may have put myself into this infinite loop of writing and rewriting in the two languages, God help me... Anyway, I'm kinda sad I don't have a tutorial in portuguese that I like anymore. But the reason I did this is that I hope you people out there could give me some feedback on this thing. I'm sure there are tons of typos and spelling errors so forgive me and please let me know. People are usually excited about this tutorial here in Brazil but never quite warn me of BS I write, and I'm surprised everytime I review it as I can always find trouble. Anyway, most of this was a motivation of having a pretty nice document in portuguese, as pretty much everything else is in english. I probably wouldn't do it if I was teaching in english all the time. So some things are not much new, but I am proud of some other things, and I like the fact it tries to be quite extensive and all in one document, organized in folders that depend on previous patches. Oh, here's the link to it: https://sites.google.com/site/porres/Tut-Eng.zip Thanks Alex

Re: [PD] 3 new gui-plugins
by JF 12 May '11

12 May '11

The auto-completion is fantastic stuff! Especially the drop-down menu addition. Congratulations Yvan, HC & JW. Is there anyway of modifying the plugin so that instead of using TAB this happens... * Create new object -> list of objects appear in full (0-9, a-z) but focus stays in object * Begin typing -> list of objects reduces as you type * See the one you want -> arrow key up/down, focus changes to drop-down box then ENTER to select desired object Is this something that is possible? I tend to go on breaks from Pd when real life kicks back in so every time I come back I find myself opening up the help list of all objects to remember what tools I have available to me. So a complete list I would find very helpful, plus I think this would aid beginners a lot too. Cheers, John.

The economics of Open source
by Pierre Massat 11 May '11

11 May '11

Dear List, I was trying to get Ardour to work last night and i came accross the forum on their website. I must say i was quite shocked to see how many posts were about money. I was equally surprized to see that the latest full version of Ardour isn't free (although you can name your price). Now don't get me wrong : I think i can imagine the amount of work that was necessary to write a software like Ardour from scratch, and i totally understand that the team who wrote it may decide that they should be payed for it. This leads me to ask two questions : 1) What are the economics of open source software, and how sustainable is the model? How does it work for Pd? 2) I get the feeling that open source developpers used to think that the idea of free (free beer...) software was cool, but 10 to 15 years down the line (that is, now) they're beginning to realize that they can't keep on doing this forever. Am I wrong here? I have been considering making a donation since i've been using Pd extensively for a few years now. But could someone tell me exactly how it works? Who gets the money? How is it split between the different developpers? For instance, i'm assuming that Miller Puckette should get a fair share of the donations since we're all using Pd vanilla at least, but i use HID a lot in my patches, so Hans should get his share too. And i never use GEM or Gridflow (cause i have no need for it at the moment), so i don't see why part of my donation should go to Mathieu or GEM's author(s). Yet i m sure that thousands of people use GEM, and these developpers should be supported as well. In short, how does it work, and how do we make this sustainable? Pierre

10 May '11

Configure and make seem to go fine but when I try to launch... Error in startup script: couldn't read file "/usr/local/lib/pd/tcl//pd-gui.tcl": no such file or directory ...perhaps I'm missing something? I'm no Linux expert. Thanks, John.
