Re: [PD] [Gem][pix_threshold] (it's about [pix_alpha] in fact)

Yo, I've got it, the background image had to be rendering between a snap and the snapped image, so using a trigger resolved this. Inside the patch there is also something I don't understand it's explained inside, just putting: [gemhead] | [colorRGB 0 0 1] turns background to blue Also I'm very interested by the shader method because it's cpu wise but I don't know enough the glsl functions for getting the same fading effect we have by using [biquad] ----- "patko" <colet.patrice(a)free.fr> a écrit : > but I still can't see the background image, > > once I could see it but I couldn't get how I did it. > +++++ > > Patrice Colet - 06 32 66 03 57 > > ----- "Jack" <jack(a)rybn.org> a écrit : > > > OK, good ! ;) > > ++ > > > > Jack > > > > > > > > Le lundi 07 juin 2010 à 21:10 +0200, patko a écrit : > > > the rendering order wasn't good in my patch, now you can see the > > fading > > > > > > Patrice Colet - 06 32 66 03 57 > > > > > > ----- "patko" <colet.patrice(a)free.fr> a écrit : > > > > > > > yes, that's what I'm trying to achieve, it just misses the > pretty > > > > fading we can obtain > > > > with biquad processing, but that is exactly that, > > > > > > > > thanks > > > > ++++ > > > > Patrice Colet - 06 32 66 03 57 > > > > > > > > ----- "Jack" <jack(a)rybn.org> a écrit : > > > > > > > > > Here a patch using GLSL and the frame buffer for feedback. > > > > > Hope it helps. > > > > > ++ > > > > > > > > > > Jack > > > > > > > > > > > > > > > > > > > > Le lundi 07 juin 2010 à 17:00 +0200, patko a écrit : > > > > > > oupse I've mixed [pix_threshold] and [pix_alpha] > > > > > > > > > > > > it's about pix_alpha rather but I think you've understood, > > > > > > > > > > > > indeed I'd like the particle reveals background image > > > > > > > > > > > > the idea is about snaping the particle system over a black > > > > rectangle > > > > > (the mask) > > > > > > > > > > > > and then turning the white pixels to alpha for revelating > the > > > > > (purple) rectangle > > > > > > that should be rendered first > > > > > > > > > > > > i've attached again the same patch but with [gemhead 5] > > instead of > > > > > [gemhead 0] > > > > > > > > > > > > +++ > > > > > > > > > > > > > > > > > > > > > > > > ----- "Jack" <jack(a)rybn.org> a écrit : > > > > > > > > > > > > > order rendering' because [gemwin 0] <=> [gemwin 50]. > > > > > > > If I understand, you want to see a background image when > > the > > > > > > > particles > > > > > > > are drawn ? > > > > > > > ++ > > > > > > > > > > > > > > Jack > > > > > > > > > > > > > > > > > > > > _______________________________________________ > > > > Pd-list(a)iem.at mailing list > > > > UNSUBSCRIBE and account-management -> > > > > http://lists.puredata.info/listinfo/pd-list

playing movies with audio again
by Julian Villegas 08 Jun '10

08 Jun '10

Hi, I have three movies, in three different (windoze) computers, I'm using a fourth one to control them. The movies are synchronized between them but the audio is always delayed. I'm sending via OSC a message from the server that upon arrival in the video clients, generate a bang to [pix_movie]. The bang is also sent to a [1< that is connected to a [readsf~ 2] (the movie audio is stereo). Is there any way that I could play the movie with audio directly? in that case the sync. problems would be over... I guess that for VJing is not so interesting, but a vanilla video player sounds to me like a natural thing to have in Pd for the rest of us that are not doing fancy stuff. I tried [pdp_yqt] but it's not available in Windows. Any help would be greatly appreciated. Julian Villegas, Ph.D. http://julovi.net Me pregunto de un modo pensativo Que significa ser Colombiano?

Re: [PD] [pix_crop] offY incoherence

I think about resolving this counter intuitive problem by using values between 0 and 1 for all computings, and apply the pixels dimensions at the end Patrice Colet - 06 32 66 03 57 ----- "Mathieu Bouchard" <matju(a)artengine.ca> a écrit : > On Sun, 6 Jun 2010, patko wrote: > > > hello, why [pix_crop] y is offsetting from the lower left, when > [gemmouse] (or logic) is starting from the highest left? > > For the same reason that GridFlow usually uses (y x) and sometimes (x > y) : > it's because of conflicting standards. > > There's worse : if you've read books involving spherical coordinates, > > you'll see that there are perhaps at least five different conventions > in > concurrent use... varying according to whether latitude is signed or > unsigned ("colatitude") and the six possible orderings of three > variables. > It's crazy. > > _ _ __ ___ _____ ________ _____________ _____________________ ... > | Mathieu Bouchard, Montréal, Québec. téléphone: +1.514.383.3801

Re: [PD] plugin~
by Kim Cascone 07 Jun '10

I've been playing around with the plugin~ help file a little and fixed it (for me at least) so it doesn't crash PdX if you open plugin~-help.pd as a text file and delete all instances of [info], [print] and [reset] messages it should work hope this is useful to someone feedback is welcome if this doesn't work

“plug & play sensors + puredata workshop”
by servando barreiro 07 Jun '10

07 Jun '10

Friday 18th/19th June 2010 “plug & play sensors + puredata workshop” This workshop it´s an introduction to the world of the analog sensors (light, infrared, ultrasonic, accelerometer) used to control audio, video, midi applications and also interactive installations. we will use the “minitronics” board in order to comunicate with the computer because it´s cheap, plug&play, multiplatform and it doesn´t require any extra knowledge to use it. we will construct during the first day a “basic” sensor controller with a pair of light sensors and a pair of potentiometers. during the second day, I will explain the different interfacing possibilities with many different softwares and also I will give and explain some puredata patches ready to “work”. (all platforms) DAy1: Introduction examples of applications with sensors crash course electricity / safety.. how to connect the sensors to the board soldering intro / alternatives to soldering Hands on….. DAy 2 how to send midi to any standard midi application. Puredata introduction how to scale data from the sensors how to “clean” data from the sensors. audio basics in pd (foto-theremin, sampler-scratching.. ) video basics in pd. personal requests,,,, more info here: —————–>>>>> http://minitronics.net/?page_id=98 and here—> http://minitronics.net/?p=60 If anybody has questions, I will be happy to respond it info(a)minitronics.net Schedule for Workshop: June 2010 18: 14:00 – 19:00 19: 14:00 – 19:00 Workshop Location: @ NK Elsenstr. 52 2HH 2Etage 12059 Berlin Participation is limited to 20 participants.

Hi all, I wanted to try out this external from Bryan Jurish but it seems to be unavailable. http://www.ling.uni-potsdam.de/~moocow/projects/pd/pd-flite-0.02-2.tar.gz is a dead link. anywhere else could I find this ? Bryan, are you here ? :) thanks! Tim

Pair performance
by Andrew Faraday 07 Jun '10

07 Jun '10

Hey All I'm interested in creating some patches for performance which require two people to play. (for instance, one uses some form of tactile control, keyboard etc to control notes while another manipulates timbre, synthesis etc. Has anyone done anything like that before? Any tips on making it go smoothly? Thanks Andrew _________________________________________________________________ http://clk.atdmt.com/UKM/go/195013117/direct/01/ We want to hear all your funny, exciting and crazy Hotmail stories.

I checked the iem ftp site and the plugin~0.2 tarball is dated 2001 could someone please point us n00bs to the src?

Updating the help patches in pd-ext
by Jonathan Wilkes 07 Jun '10

07 Jun '10

Hi list, I would like to update the help patches for all the vanilla objects and PDDP objects with the revisions I've posted at: http://puredata.info/Members/jwilkes/doc/view?searchterm=revised%20doc%20fo… (Almost) all these help patches use the PDDP template and have a "META" subpatch that gives info for object name, description, xlets, author(s), library, help patch author(s), and an initial attempt at some keywords that describe each object's behavior. (all the vanilla objects are located in the 5.Reference folder) A few questions: 1) What's the easiest way to do this? Do I just post a .tar file containing the help patches in 5.Reference? 2) Help patches for expr, nqpoly, and a few other externals are located in 5.Reference. Is this a mistake-- shouldn't they be located in their respective folders?
