[PD] Structures lists
Hello, basic : the manual about data structures and lists seems out of date ... what would be the straighforward way to deal with (point to) many lists of different lengths (matrices inappropriate) without declaring lengths at first ? (using float arrays in data structures requires prior length declaration , correct ?)

Actually Guido, I think I read you on the Pd forum few days ago and checked your patches too, nice work. As for the documentation. Personally, a great part of my first attempts at working with glsl in Pd were completely mined by the absence of a wrapper object for the glsl compilation; the lack of a [pix_shader] or [a_shad] for instance. It would be useful to have [pix_shader] included in GEM. It might sound silly, but as Guido mentioned, getting a shader to work it's a much of a trial-and-error exercise. Thus, in my experience, it took a lot of time to figure out where to look for bugs or problems. I needed to study glsl (obviously) to start understanding; but I believe that users would benefit from the inclusion of some initial, basic information within the glsl help patches. For example, shader with rectangular textures won't work if you don't switch the [pix_texture] mode adequately. This is not explained anywhere in Pd, and, yes, of course you can getting to it by learning with on-line resources, but it would be far easier to place a [comment] somewhere in the Pd patch. (I don't think it's there already, but please tell me if so.). this is what the 1st example do explain. at least, i thought it does. maybe it should be a bit more verbose. Shortly, imho the present glsl help are very complex for a noob because: _there isn't an official wrapper, so the loading/compilation process is visible and appears quite confusing. wow. this is strange for me. I always do a copy/paste. anyway, there is now a _glsl abstraction since i use it for the 14th example. other examples can be update to use it. _uniforms and how to control them from a Pd patch are not explained anywhere (within Pd) this is used (but not explain) in most example. i believed an example is better than text, but it look like i'm wrong. _basic and clear info about getting a new shader to work in Pd are missing you just have to imitate the basic example... of course, the whole glsl thing is complex and need further study anyway, but it would be awesome to inform the glsl in GEM with the stuff above. feel free to update help and examples. i thought it was clear. examples provide the information i wish i had before creating them... cheers Cyrille M On Tue, Dec 27, 2011 at 2:10 PM, cyrille henry c...@chnry.net mailto: c...@chnry.net wrote: Le 27/12/2011 13:02, Guido Tamino a écrit : Hello, actually the [pix_shader] abstraction comes from a depth of field simulation I made with glsl/gem a while ago.

If anyone wants to try it out, the depth of field patch is pretty self-explainatory and should work just out of the box. http://vimeo.com/30188933 Before being swamped with work I was interested in porting Vade shaders and other glsl stuff to PD. I implemented his blur shaders (motion blur, zoom blur and fast blur) and they all seems to work fine but a lot of work has to be done before using them as solid generic effects. http://guidotamino.it/__**download/glslBlur.ziphttp://guidotamino.it/__download/glslBlur.zip http://guidotamino.it/**download/glslBlur.ziphttp://guidotamino.it/download/glslBlur.zip A couple months ago I opened a discussion with Cyrille on the theme but we were both too busy with work to fully dive into the subject. since then, i made a good triangle blur shader to work with a modified version of guildo patch. i commit everything as a gem example yesterday. In the meanwhile I played around with the optical flow experiments by the jitter community with nice results, a demo could be seen here: http://vimeo.com/30517302 nice. I'm definetely interested in developing a set of glsl wrappers to make the whole thing easier for a beginner. I am a beginner myself and I had some tough times trying to figure out things like how to multipass glsl effects or how to feed multiple textures to a shader. This kind of stuff is almost undocumented and needs a lot of trial and error in order to be understood. there are few multipass example in gem. I try to make 1 example for each technical possibility. nothing is fully documented, but i think everything is documented. at least, everything that i'm aware of. (i was also a glsl noob before making gem examples...) do you think that more multipass example are needed? or is it just that since it's complex, it need time to be fully understood? cheer Cyrille Best, Guido Il giorno 27/dic/2011,

Re: [PD] [PD-announce] pd 0.43-1 test7 (!) available
The paragraph mode is not the cause of the freezes as far as I have
seen, it just highlights the situation when there are bugs. I think we
should first discuss fixing the bugs before changing the current mode of
operation.
As for the fixes in pd-l2ork, it would be great to have them in vanilla.
Could you refactor them against vanilla and submit them to the bug
tracker? Then they can be reviewed and included.

The challenge remains, though, regardless of the approach. If a
particular call was called and it shouldn't have, parsing it out as
part of a paragraph or a line makes no difference performance-wise,
but it sure does make a world of a difference in terms of gui (or
parts of it) becoming unresponsive, since when the parser is in the
paragraph mode one will lose up to entire paragraph instead of a
single line (which in this case would not have any effect since the
line should've never been called). This is the part I was originally
referring to in terms of porting forward. If you look at the pd-l2ork,
it has much more detailed sanity checks for individual calls inside C
to make sure those calls are needed at all in the first place. Once
they are identified, you can wrap them in their own catch inside tcl
code (it that is indeed where they are being called)...
As for sanity checks, I don't think that really makes anything better
per se beyond whatever user enters manually via message to pd since
the 0.42 code already checks for sanity of those messages in its syntax.
The only time I encountered tcl breaking in core code of the 0.42
branch was as part of the network code (please note I mention here
vanilla as I haven't checked all the externals for proper behavior).
And if you ever tried debugging that you probably noticed just how the
tcl breaks. Namely, you could clearly see how one message inside
buffer was asynchronously overwritten midstream by another ending up
in a garbled output. Now, I know from our previous correspondence that
socket data incoming from a netreceive object apparently should output
in sync with the main loop, yet this problem was persistent until I
changed how the netreceive object behaves. In pd-l2ork all netreceive
sockets schedule received output as part of the guiqueue rather than
directly pushing the message out of an outlet no matter when it
receives it (or whenever suggested scheduler tells it to read from the
socket). This problem network-wise was much more apparent when there
was a heavier network traffic, while it almost never happened in low
throughput situations.
Long story short, I have not had gui freeze in pd-l2ork for over a
year now and so far I see no benefit in switching into a paragraph
mode as even if there is a huge performance benefit, the potential
penalty is the return of the gui freeze which renders any such
performance gains useless.
Quoting Hans-Christoph Steiner h...@at.or.at:
That is definitely true. It is possible to make pd-gui execute
line-by-line by setting the buffering on the socket to be
per-newline, then reintroducing the logic that used to be in the C
code. But I think its faster to have Tcl parse, compile, and
execute the code in larger blocks, but I don't have any data to back
that up.

I believe the difference between 0.42 and 0.43 is that the C code in 0.42

The 0.42 code wasn't airtight (checked for newlines at which {'s were
balanced with }'s - this happened to work for all the TCL that Pd
generated,
but one could construct valid tcl code that gave false positives.) So I'm
not in favor of 'fixing' 0.43 to work like 0.42 in this aspect. But I sure
would like to be able to tell the interpreter to bull through if
any individual

when they manifest themselves.

The 'catch' is already in place in Pd 0.43 in
pd_connect::pd_readsocket, and that is indeed what is printing out
the Tcl error dump that started this discussion.
As for whether pd-gui stops working after an error or not, I think
this is a behavior of the Tcl interpreter, not Pd 0.43 or Pd 0.42.
In both Pd 0.42 and 0.43, fatal errors stop the Tcl interpreter.
Try sending a message with { in it. In both Pd 0.42 and 0.43,
the Tcl interpreter will print an error message for non-fatal
errors and then continue to execute the next commands.
About the bug report, that particular bug report shows a bug where
Tcl commands are being split in the middle of the line, causing
incomplete commands to be
Re: [PD] Android device for PdDroidParty
If all you want is something to act similarly to TouchOSC, then I'd say get Charlie Robert's Control http://charlie-roberts.com/Control/. You can design multiple interfaces a-la TouchOSC using simple-enough code, and it's available on both iOS and android. I tested it on a Samsung Galaxy and an iPad. If I'm not mistaken, PdDroidParty is self contained, meaning you don't connect to a network and communicate with a DAW on your computer, but rather the phone or tablet is running Pd to make the music. RJDJ and RJ Voyager also fall under this category, although I think they're originally intended for iOS only.

Or open the file on a sound editor that allows you to read raw data, and provide the number of channels, sr, etc. (probably you found out a solution by now, anyway) Send readsf~ a message open xxx.aif 0 124 2 2 b' (possibly replacing the 2 2 with a different number of channels and bytes per sample).

[PD] questions about PD-extended 0.43 build on Mac (GUI-oriented)
hey folks, new PD user here, coming from Max 5 on a Mac and trying to rewrite my patch in PD. i read about the new .43 branch builds of pd-extended and how they had a few usability improvements over the older branches. so far i've downloaded the 12/21 and 12/30 builds of pd-extended for Mac. i'll have lots of questions but for now these will suffice: 1. is there a way to get the right click context menu for objects working in .43 on the Mac? i read that a GUI plugin is responsible for this, but it seems it should be included in this extended build. 2. also read about key bindings-VERY interested in this as i have some RSI issues and shortcuts would be helpful for common tasks. 3. is there a way to edit GUI characteristics (global font size, key bindings,etc) by changing some items in a config text file? i've read that the rewrite uses Tcl/Tk but i'm not really a programmer though i can edit and modify simple CSS or PHP scripts. 4. lastly - i know the 0.43 branch is considered experimental, but if there's a relatively stable .43 Mac build somewhere that could be recommended it would be appreciated. the Dec 21 build is OK though right-clicking to get Properties or Help lags a lot. thanks in advance, scott ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
