[PD] tcpsend disconnects

[Csaba Láng]

Hi list,

I am struggling with this for many years, and looks like cannot solve the
issue of the tcpsend object which disconnects by itself. Would be easy to
reconnect if I had an outlet with the info if connected or not like netsend
has.
Is there any solution to keep it connected stable?

Any hints welcome.

Or the other way around what video codecs and what extension can be used to
be played on Windows 11 by pix_film?

Re: [PD] Rectangle object does not understand [width 7( message

[Csaba Láng]

Cyrille,

thanks for your answer. I have not seen the sense to send a simple patch as
it would not show the behaviour of the rendered Gem window under wsl2.
Anyway, I have to use both Windows and subsystem Linux as on Windows does
not work the shell or command objects while under Linux the above mentioned
[width( command to the 2d shape objects such as triangle, rectangle or
circle.

Thanks for your support anyway.
Best,
Popesz

Re: [PD] Rectangle object does not understand [width 7( message

[Csaba Láng]

You misunderstood me. I did use a simple patch and of course I used the
width message correctly to the first inlet of the rectangle or circle
objects with numbers from 1 to 7.
Under windows works correctly.

Re: [PD] Rectangle object does not understand [width 7( message

[Csaba Láng]

I have found this discussion on the web.

https://github.com/microsoft/WSL/issues/2855
Does it take me closer to make it work?
I have a NUC i9 Beast Canyon computer with the integrated graphic card in
it https://simplynuc.com/beast-canyon/

Surely I have tried the simplest patch from the rectangle-help.pd. Tha was
my first to try

Re: [PD] Rectangle object does not understand [width 7( message

[Csaba Láng]

Indeed too complicated, especially taking into account that I have
something like 100 patches using the same thick lines. So it is not Gem
related according to you but openGL?

Re: [PD] Rectangle object does not understand [width 7( message

[Csaba Láng]

By the way, the same issue with the circle object. [width $1( is just
ignored with the draw line message.

[PD] Rectangle object does not understand [width 7( message

[Csaba Láng]

Hi list,

I have a windows system with wsl2 Ubuntu distro on it. Installing on the
ubuntu subsystem pd and compiling Gem from Dekken, the rectangle object
does not understand the [width $1( message in case I want to draw bordering
lines. On windows it has no problem and other ubuntu not subsystem can
handle the message as well.
Does anybody have any clue how I can fix it?

Thanks in advance for any ideas.

Best,

Is there a chance to have this issue fixed?
Without a correct Gem render, my life lost its sense.

for some time already my Gem window cannot render in the full Gem window
but only in the left bottom corner
[image: Screenshot 2022-06-23 at 13.34.04.png]

My default gem window is gemglfw3window as it was suggested earlier by
Iohannes.
I am on MacOS 12.3.

Re: [PD] Gem window and fullscreen on OS X Was: GEM and video playback broken in MacOS?

[Csaba Láng]

Peter,

In April I wrote this but never got an answer:

since I moved to  [gemglfw3window] as gemwin has not been created on since
Big Sur I am unable to make borderless screen.
Is there a workaround? [fullscreen 2( is not my option.

Best,

Popesz

[PD] Gem without gmerlin

Dear list,
I am trying to compile Gem on Ubuntu 20.04.3 LTS witrh pylon, but make
fails with gmwerlin problem.
I have found a 2 year old thread here
https://lists.puredata.info/pipermail/pd-list/2019-02/124601.html
which says that it is almost impossible to make gmerlin work due to bad API
and lack of updates. latest is from 2012.
Is gmerlin needed? Can i ignore it and compile gem without gmerlin?

Please advice!

Re: [PD] From telnet to netreceive whole sentence

[Csaba Láng]

Iohannes,
tried your way, bit tricky for my kind of knowledge, but the idea with
routing just was the perfect solution.
2nd outlet of [route] did the job, it natively adds 'list' to the front of
the words with sapces which was the missing part for text3d.
All works perfectly and all the words with spaces are just perfectly
rendered in gemwin.

Have such a lovely day as I have,

Re: [PD] From telnet to netreceive whole sentence

[Csaba Láng]

I try to make it simple without unicode, let's say.

What if I add [list $1 $2 $3 $4( to text3d where each $ is a word (max
number of $ is the amount of words in the longest sentence)
How can I achieve not to display 0 0 0 at the and of the list if number of
words are less than max number of words in the longest sentence.

Re: [PD] Gem: Looking for suggestions for camera / capture setup

[Csaba Láng]

When I started this project Gem used the pylon 2 backend. The new cameras
of basler are based on pylon 5. Iohannes that time updated the backend in
Gem to 5. You have to install pylon 5  before compiling Gem showing the
path to pylon. And that’s it.
GigE is not a good solution as the data is more than GigE can handle. I use
usb3 hybrid cables up to 50m.
By the way I use this camera:

If you wanna see some example videos, download the Rayaction squash app,
register (preferably with email as some functions are buggy still) and
check out the video under each exercise.

Re: [PD] Gem: Looking for suggestions for camera / capture setup

[Csaba Láng]

Hi All,

I have made an interactive squash system with Pd based on Basler's high
speed cameras for machine vision. I use mainly above 200fps of 5 USB-3
cameras each of them on a separate USB bus.
The balls can fly with a 200km/s speed and I hardly have a problem
analyzing their position with pix_movement.
Surely the biggest problem is having a display with a similar fresh rate,
but if you do not need to render the image then it is fine.
The computer is a 3GHz processor and 32MB RAM with Ubuntu 19.04 if I
remember well.

Best,
Popesz

Re: [PD] Image from shader back to Gem

[Csaba Láng]

I am totally lost, I attach my shader and the patch which I made the
screenshot of at the beginning of this thread.
Could someone show me how to achieve the texture on a rectangle 16 9 so I
can rotate and crop it and not only as a mask, as it is now in the patch.

Probably totally easy just cannot figure out how to add the pix_snap or
pix_snap2tex

Thanks Miller, indeed this is exactly what I am looking for.
Fighting with pix_snap no images coming to the texture. Is anybody
interested in the shader? Should I share the folder?

I used pix_snap before for correction but it was a hand made correction,
while with the shader I can make it automatic and more accurate.Can it be
this too (shader and Gem) somehow connected?

Re: [PD] OSC problem

[Csaba Láng]

Gents,

the problems is that oscars for some reason does not send the / at the
beginning of the osc signal, just 'list trigger0 0'
and for this reason the routeOSC does not understand what it has to route.

What do I miss again?

I have
[udpreceive 7000]
|
[oscparse]
|
[list trim]
|[routeOSC /trigger0 /trigger1]

and nothing comes out on the outlets.


hmmm

Re: [PD] OSC problem

[Csaba Láng]

Scott,
thanks a lot. Using the extOSC, Unity started to send me the OSC signal,
after using the magic solution for Windows problems, which is a simple
restart.
Now I have the only problem that sometimes the slash is missing for an
unknown reason but if I fix it, I am OK.

Thanks for all the solutions you guys suggested.

Have a nice day!

Re: [PD] OSC problem

[Csaba Láng]

Scott,

thanks for the Unity part suggestions. Screenshots are welcome, patch is
even better :)
Just to be clear you suggest both solution in one time: extOSC and the
udpreceive - oscars, or the udprevceive works already with the OSC I use
now from Unity.

Will come back if tested the extOSC package for Unity, probably in 12 hours.

Best,

Popesz

Re: [PD] OSC problem

[Csaba Láng]

I haven’t used slipdeck at all. It is somehow built in the tcpreceiver as
the message from the console is from the moment I changed the port to the
required 7000.

[PD] OSC problem

[Csaba Láng]

Dear list,

I have made a little program in Unity to send over OSC (port 7000) 60 times
per second if a trigger was touched or not (1 and 0 respectively)

However, any of my tries if it was over localnetwork or via IP to port 7000
nothing comes to Pd.
Tried udp, tcp and netreceive but cannot catch any of the signals which
looks like this
/trigger0/0 or /trigger34/1

Anyway, netreceive print to the console: slipdec: maximum packet length is
65536.

What could go wrong?
When I use Arena or Artnet the OSC is running with all the info I need, but
Pd is muted totally.

Best,

The reason I thought of removedollar, to not have 10 elements on the

Looks like [list store] will be the easiest choice.

[PD] matlab camera calibration app to Pd

[Csaba Láng]

Dear list,

I have found an app on Matlab, which can handle any lens distortion with a
fisheye lens.
https://uk.mathworks.com/help/vision/camera-calibration-and-3-d-vision.html
My camera would send the image through the matlab app to have a flat image
which I would like to send to GEM and analize with the pix_movement if
there are any changes between the frames.

Did anyone try it before? Is it possible to pass through live cam input and
send the corrected one to Pd immediately?

Hope someone has a good idea or made it before.

Re: [PD] Subprocess CPU core check

[Csaba Láng]

Dear list,
I am getting closer to the solution of binding process to a certain core
with taskset.
e.g. taskset 0xa gedit will bind the gedit to the tenth core.

Now the problem is that I cannot identify the subprocess by its name as it
will be pd too, and the PID will be always different so cannot use that
number too.
What would be the logical solution for starting the subprocess from pd with
the taskedit command?

Thanks in advance for any help,

Re: [PD] object opposite of change

[Csaba Láng]

Chuck,

thanks for the hint, sounds good. I will give a try tomorrow, but already
started to have some other solutions, and I played with time delay. I mean
under it to compare XYZ coordinates in time, if delta is close to the
noise, than I expect that the object (hand) is still.
However, there are bigger problems, as the hand disappears if the hand
touches the background, in this case I have a lost hand. Assuming that I
lost on the very last position, just before touching the wall, I can get a
quite close parameter of the hand.
Still need some tests, but together with yours probably can have a better
assumption.

Re: [PD] expression with arctn

[Csaba Láng]

Back to the difference of Iohannes' suggestions, looks like [expr atan...]
gives results only from -90 to 90 degrees, [atan2] gives from -180 to 180.
And the atan2 is 90 degree rotated: atan2 results 0 degree on (1;0) while
the expression gives 0 degrees on (0;1) and (0;-1).

[PD] expression with arctn

[Csaba Láng]

Dear list,

how would you calculate with an expression this formula:

arctg(y/x)


looks like tan, sin, cos cannot be in the expression, does it mean I have
to brake it into parts?

Dearest list,

is there any object which only gives me a value from a constantly changing
random numbers when it stops for a while, let's say for one second or so?
I am looking for the parameters of tracking hands from Kinect like motion

Re: [PD] audio via HDMI output terminates Pd

[Csaba Láng]

Did not manage to fully repair the audio problem on HDMI.
Reinstalled pd with apt-get, and started with *pd -alsa -alsaadd pulse
-audiooutdev 5 -noadc* where 5 is the HDMI output.
Now the 2 minutes video play until the end and quits with error as below:

pd: pcm.c:1167: snd_pcm_prepare: Assertion `pcm' failed.
Pd: signal 6
pd-extern: EOF on input

and

pdsend errorname: >>error writing "sock55d791aa9930": connection reset by

Does it mean anything which takes me closer to solve this issue?

[PD] send a multiatom control message via netreceive

[Csaba Láng]

Dear list,

I need to send a control message back to the sender on the network if the
message has arrived to Pd.

this part works fine:

[list /LOGIN 6(
|
[send /OK $1 $2(
|
[netreceive]

Or the first message can be [list /BEGIN CODE50(
I need to make in the first message after list 2 or 3 variables [list $1 $2
$3( where the variable sometime a float, or a symbol. With [pack s s s]
does not work, as even I change the float to symbol, it won't accept it. It
should not be so difficult, but I am stuck totally.

Re: [PD] ugly font edges on non-black background

Hi Roman,
I tried many fonts, truefonts behave the same way.
Check the screenshot:
[image: uglyfontwithalpha.png]
I tried all the font sizes from 5 to 100 (20 is default) and play with the
Z axe to make it smaller, the final effect is the same every time.

Does anyone have a best practice with the fonts on alpha on any background
than black?

[PD] multiprocessing for GEM

[Csaba Láng]

Hi dearest list,

I am looking for a multiprocessing solution for GEM itself.
What I found from Miller's paper:
http://www.pdpatchrepo.info/hurleur/multiprocessing.pdf
clearly deals with only audio multiprocessing as the object pd~ indicates
its usage.
Is there any method to spread GEM calculations among 4-8 processors?

Best,

Re: [PD] Gem window bigger than fullHD

[Csaba Láng]

True, looks like I forgot something at the end.
Anyway, my latest solution to send big resolution to multi projectors is
NDI through gigabit ethernet.
Just make the rendering in gemframebuffer, the Gem window is just a preview
on my main screen.
https://github.com/gogo2/pd-ndi/releases
I honestly recommend it.

Thanks,
Popesz

[PD] Gem window bigger than fullHD

[Csaba Láng]

Dear list,

I have 2 fullHD screen connected to my pc with Ubuntu 18.04, but pd cannot
create bigger Gem window than the size of my first screen.
Is there any trick I do not know about? Dimen 3840 1080 just does not make
any difference.

Re: [PD] fish eye camera distortion correction

[Csaba Láng]

I am getting closer to the solution, however have a bigger problem than
expected.
As the camera is pointing at the projection surface, I have the classical
video feedback effect. As a result, the corrected image is getting bigger
and bigger, and I loose more of the image,
than the fish eye correction was made with the [curve3d].
how could I move the image after gemframebuffer and move back with the
offset of the pix_snap?
Or what for the offset is made?
Is there any method to avoid the video feedback in pix_buffer?
Looking forward to any brilliant idea :)

Re: [PD] fish eye camera distortion correction

Thanks for the ideas.
Luckily I will snap the pix just once a second or two. Hope the processor
can handle it.
Which correction is easier, curve3d or the shader?

Re: [PD] fish eye camera distortion correction

[Csaba Láng]

Looks good, but now a bigger problem came up.

My aim is to correct the fish eye distortion for pix_movement and
pix_multiblob analyses.
Which means first I have to make the curve3d correction and then use those
pixels in pix_multiblob.
Is it possible?

[PD] ignor bigger blobs with pix_multiblob

[Csaba Láng]

Dear list,

I would like to detect small objects with pix_multiblob, but to be sure if
anything bigger than my observed object appears in the view of the camera,
it will not be taken that into account.

I tried to achieve it like this:
for the beginning checking 3 blobs with [pix_multiblob 3] and with list
split separate all the parameters multiblob gives.
Examining the sizes of each blobs, packed it to one string and trying to
tell which number is the smallest, that x y positions I want to follow.
Unfortunately big objects are divided into very small blobs, so this method
does not really work well. Is there any other solution to find the smallest
blob out of 3-6 blobs and find the position of that blob?

Hope it is clear what I tried to explain.
Best,
