i ! i try to use a patch in pdmtl : gems.multicrop . I want to paste a pixblob in each square of the grid and connect a camera for, with a alpha fade, for do appear that there are areas or movement. But it's a very very good and interesting patch and i don't understand where can i put my pixblob. Do you use it ? do have any council for me ? thanks ! thomas. _____________________________________________________________________________ Ne gardez plus qu'une seule adresse mail !

[PD-announce] Pd 0.41-2 released
by Miller Puckette 21 Feb '08

21 Feb '08

Hi all, three more bug fixes, including one I forgot to throw in the release notes: I figured out why cutting/pasting text into boxes didn't work on MACOS or Windows. The others: a crash bug on windows when restarting DSP repeatedly, and netsend/netreceive sometimes dropping data. cheers Miller _______________________________________________ PD-announce mailing list PD-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce

the behaviour of [list length] has changed!!
by matteo sisti sette 21 Feb '08

21 Feb '08

Hi, Up to at least version 0.40.1, [list length] used to output the number of arguments of a list or message (exactly as documented), which means that [walk the dog( had length 2, not 3. Now, in 0.41-2, it treats the message as a list and outputs the length of the list, that is [walk the dog( has length 3 which is the same as [list walk the dog( Just compare how the help patch for [list length] behaves in version 0.40.1 and in 0.41.2 (not sure where the change happened). This new behaviour may perhaps be "better" than the old one (it is more coherent with the behaviour of all other [list] objects which always convert any message to a list), however: 1 - this is DISASTROUS for backward compatibility. Patches written for older versions will behave differently on the new version! 2 - the documentation (help patch) is unchanged, and there is no ambiguity in it: it describes the old behaviour. Was this change intentional? Is there a reason so good to be worth such a huge break in backward compatibility? If so, the help patch should be updated. -- Matteo Sisti Sette matteosistisette(a)gmail.com http://www.matteosistisette.com

Dynamic Object Connections through OSC
by Jonny Martyr 21 Feb '08

21 Feb '08

Hi there, I'm new to this mailing list and I have a question regarding dynamically connecting objects together using OSC commands. I would appreciate any help that anyone can provide. Essentially I am building a Flash application in which the user can connect together different blocks to build synths, much like a simplified version of PD. I am able to pass messages between Flash and PD using OSC, and so can dynamically create objects and edit their parameters from Flash. However, I do not know how to create the connections between the various objects in PD without actually drawing them manually. Does anyone know of a way around this? Possibly using send and receive commands? Many thanks, Jonny Martyr _________________________________________________________________ Telly addicts unite! http://www.searchgamesbox.com/tvtown.shtml

Re: [PD] [GEM] model UV texture map

Is there a way to map an image along a model's uvs? the [pix_image] seems to use a rectangular projection image mapping system.

pd/gem per-pixel image manipulation
by Martin Leopold Grödl 20 Feb '08

20 Feb '08

hi everybody, i want to do per pixel image manipulation in gem (running pd.extended 0.39-3). so far i've been trying pix_dump with a lister and then until with packel to access individual rgba values in a loop. after i do the manipulations i accumulate them back into a list using repack and send it to pix_set. it all works out pretty smooth. only problem is the list that gets sent to pix_set somehow seems to get one float prepended, which effectively shifts all the rgba-values one step and messes up the colors. any advice/examples on a correct pix_dump / pix_set setup? ...any other solutions? thx, martin

detecting file error in readsf~
by matteo sisti sette 20 Feb '08

20 Feb '08

Hi, As everybody knows, [readsf~] outputs a bang on its last outlet when the end of file is reached. If you send it an [open xxx( message and then a [1(, where xxx is an _invalid_ file name (i.e. a file that doesn't exist or cannot be opened), I have observed the following behaviour: After the [1( has been received (1.45 msec later logical time: is it one signal block?), a bang is output through the last outlet, as if the end of the file was reached. That is, playing a file that does not exist is equivalent to playing a zero-length file. Do you consider this to be the correct behaviour? It becomes a practical issue when for example you want to implement a loop: when the end is reached, play again. If an invalid file name is used (which cannot be detected in any way), this will generate a dsp-block-rate loop. In my ideal world, it would work like this: -readsf would have one more outlet and would bang on this outlet in case of error, and would _not_ bang the end-of-file outlet on error -the error bang would be output when the invalid [open( is received, not when the 1 is received (which is when the error message is currently printed) I think an invalid file name is a very common situation and it should not be considered as an "exception" (i.e. error message on stderr + do nothing), but rather as a detectable condition so that it can be reacted upon (e.g. showing something on a GUI, inhibiting operations that would generate error messages, etc). On the other hand, while a file-error-bang outlet does not exist, although strictly speaking I think "playing an unexisting file" is more equivalent to "not playing" than "playing a zero-length file", I do recognize that the current behaviour is practically better, since it at least permits to detect the anomaly (e.g. by using a [timer] to detect a too-early end of file), though it cannot be distinguished from a too-short file. I guess some kind of "serious" error/exception handling won't probably be considered before a version 2 of PD, but I think this is an example of "anomalies" that should not be considered errors/exceptions at all (at a pd level) but rather special conditions to be handled by the patch. In my opinion, trying to open a file that cannot be opened is as "normal" as sending a 2-element list to a [list split 4]. -- Matteo Sisti Sette matteosistisette(a)gmail.com http://www.matteosistisette.com
