Re: [PD] pd-l2ork feedback

Thanks for the report. mknob is not accelerated, so you will get slowdowns, but those should not be any slower than vanilla pd. I will investigate further to see if I can reproduce that here and if so, find the source of the problem.

pd-l2ork feedback
by András Murányi 03 Mar '13

03 Mar '13

So, I've played around with the last git, here are some things I've noticed: - miXed/toxy is not in pd-l2ork and it's perfectly alrite because some kinds of [widget] work while others not. - [flatgui/popup] is installed by default but it throws an error when clicked on: Invalid command name "pdtk_canvas_mouse". - moving a simple GOP abstraction with a single [mknob] in it takes like 5 minutes (!) on a 2.4GHz dual core when the patch is big. It's fast however when the patch is simple. Undoing the movement is not instant but it is quick (~5sec). - nested GOP subpatches show off their outlines and xlets. -- Murányi András

Gem:Convert 3d shape(obj) into a string of characters
by ronni montoya 03 Mar '13

03 Mar '13

Hi, i was wondering how can i convert a 3d shape (obj file) into a string of characters using Gem/pd? Is it possible to get a list with all the vertex values of a obj file using Gem? If not, which other options do exist? thanks in advance R.

Hi , i was wondering if anybody have implemented the shannon entropy function in pd? Do anybody have tried measuring entropy of a signal? cheeers R.

Simple Kalman filter
by Joel Matthys 02 Mar '13

02 Mar '13

I just completed a very simple 1D Kalman filter Pd external. I haven't really done any documentation on it, but it seems pretty robust for cleaning up 1D sensor inputs. The source is here: https://github.com/jwmatthys/kalman-pd Joel

debian: patch with some gops stalling
by João Pais 02 Mar '13

02 Mar '13

Hi everyone, I have a subpatch with ~20 gops showing (each with an array). When opening the subpatch, or changing desktops to the desktop where the patch is, there is a pause of ~1m, until the subpatch draws. During this time no sound can be produced, and only shortly afterwards does midi work again. This happens only in debian, not in windows 7. is there something that can be done to make this better? I'm using debian squeeze 32b, on a thinkpad x61 (2 cores, 4Gb mem) Thanks, JoÃ£o

Re: [PD] check this out
by Marco Donnarumma 02 Mar '13

Yes, it's emg+accelerometer detecting fingers position as hand gesture. Although, it's difficult to call it a "gesture" recognition. Besides, possible gestures seems to be limited to the recognition pattern they provide. Which overlook the real capability of gesture following, which is the possibility of defining gesture to recognise on the go. As Pedro pointed there has been a good amount of research in this area, specially in HCI, for the past 5/6 years. This is the natural outcome of those studies. They're trying to bring to the general public and out of the labs a gestural biosensing device, and this is great. Still, in my experience, emg sensing has very different calibration time, which depend on some bodily aspects unique to each person, and the environment where the user is. That is, for some, an emg sensor may calibrate in one minute, for others in 20mins. They claim to have better (and yes, patented) electrodes. Unfortunately, we'll see the device next year (claimed ship "late 2013"). As often these days, media run the (fast and soon forgotten) hype of a good 3d mockup and a well-edited video of applications. Let's see what happens later on when we can try the real thing! It's exciting to see a follow up in the industry to this specific artistic and research area of interest. and I'm sure there will be more of those coming out. from us too :P -- Marco Donnarumma New Media + Sonic Arts Practitioner, Performer, Teacher, Director.

create/access udp sockets from within pd
by Matthias Blau 02 Mar '13

02 Mar '13

Hi list, is there a way in pd to send/receive udp packets via sockets? The problem at hand is to control an Outline ET250-3D turntable from within pd. This turntable can be controlled via udp, which works in principle by using mrpeach's udpsend. Unfortunately, the table responds to a different port every time a udp packet is sent to it, which means that udpreceive and friends will not receive the answer, as they listen to pre-defined ports. One can however communicate via sockets, i.e. in python, the solution is: ---- from socket import * ServerIP = 'xx.xx.xx.xx' Port = 6667 data = bytearray([4, 0, 0, 0]) # command to query table position client_socket = socket(AF_INET, SOCK_DGRAM) client_socket.sendto(data, (ServerIP, Port)) recv_data, addr = client_socket.recvfrom(2048) recv_data= [elem.encode("hex") for elem in recv_data] ---- Is this possible in pd as well? Or, as an alternative, how would one use a python function from within pd to accomplish this? Thanks, Matthias

can't load gridflow 9.13 on Mountain Lion?
by Tedb0t 02 Mar '13

02 Mar '13

Hi all—I've been trying to install Gridflow, but it doesn't work entirely yet. I added the /Library/Pd/gridflow and /Library/Pd/gridflow/abstractions paths but when I try to (for instance) make a #redim object, I get: #redim ... couldn't create /Library/Pd/gridflow/gridflow.pd_darwin: dlopen(/Library/Pd/gridflow/gridflow.pd_darwin, 10): Library not loaded: @executable_path/../../lib/libpng12.0.dylib Referenced from: /Library/Pd/gridflow/gridflow.pd_darwin Reason: image not found [import]: can't load library in 'gridflow' and if I try to make (for instance) a #many object, I get a whole ton of ...couldn't creates but without further information. Am I doing something wrong? —t3db0t
