(GEM) Getting the z-buffer value of a pixel in a rendered image
by Matteo Sisti Sette 16 Jun '11

16 Jun '11

Hi, Is there a way in GEM to take a snapshot of a rendered scene (such as with pix_snap) and save the z-buffer information, for example saving it as an extra channel? (e.g. have the z value saved as the alpha channel)? I'm interested in getting an image of the scene as it would appear if it was captured by a depth sensor like a Kinect... Thanks m.

file/print function?
by João Pais 16 Jun '11

16 Jun '11

Hi, I was using the file/print function [not the print class] last week, and ran into some issues. Does anyone use this function regularly? My system is XP with pd-ext 0.42, or pd-van 0.43 (I think there's no change between versions). All versions save the file with no problems. But, on windows, the file can't be opened by any program: Gimp, Inkscape, Acrobat, ... But in Ubuntu (same Pd versions) the file created has no problems. I also have the following suggestions: - printed surface: print only prints the visible canvas area. Which is not good, if you have a big patch (or in my case, a data structure score of around 22 A4 pages, canvas size of ~10000 points). I tried editing the patch with a text editor to make the canvas size bigger, but it didn't help. I would suggest to either to make the whole canvas exportable by default (independently of what's visible in the window), or an option to either keep it as it is, or export the whole canvas. - a couple more print formats would also be nice, if that's not complicated. For example: - direct to the installed printer (might assume an new print settings window, etc, a bit complicated) - tiff or png Best, JoÃ£o Pais

The final question about Arduino
by Matteo Sisti Sette 15 Jun '11

15 Jun '11

Hi, At the end, in order to figure out all the weridnesses regarding the apparently different behavior of the Arduino on different platforms, I only need to answer a simple question, well two simple questions: 1. Does the StandardFirmata firmware send the firmware name and version every time it accepts a connection on the serial port, or only when it is powered up or reset? 2. Is the action of opening the connection (i.e. the "open" message you send in Pd to the [arduino] object) supposed/expected to cause the arduino to reset? This is slightly OT but it is relevant for working with [arduino] in Pd. Thanks m.

Hi, With Pd 0.42.5, Gem 0.92.3, Ubuntu 10.10, sometimes the gemwin randomly closes itself (without crashing Pd). Has anybody experienced the same? thanks m.

pix_film can't open almost any file after upgrading to Ubuntu 10.10
by Matteo Sisti Sette 15 Jun '11

15 Jun '11

Hi, I've recently upgraded ubuntu 10.04 to 10.10, and I had to uninstall pd-extended and reinstalled the new package for 10.04. After that, pix_film crashes when I try to open many video files that I used to be able to open without issues. It crashes with a few MOV files encoded with mjpeg but doesn't crash with some other AVI files also encoded with mjpeg (don't know if it was the exact same codec or not) (all these are files it used to be able open), and so far it crash with ANY new file that I have tried to encode with ffmpeg, with avidemux, both mov and avi and with several different codecs. I can't find any format I can generate with ffmpeg or avidemux that pix_film will open without crashing. Has anyone experienced anything similar? I'm desperate, as this breaks almost all the patches I was working on and I can't seem to find even a workaround, such as recoding all videos to a format that would work. Just hoping someone has had a similar issue and figured out what got broken when upgrading to 10.10... This is Pd Extended 0.42.5 which has Gem 0.92.3, as it ships in the Package for Ubuntu 10.10 downloaded from puredata.info. Needless to say I can open these files in just any other software other than Pd. Thanks in advance m.
