Re: [PD] Extended View Toolkit

Hi, in GEM the object pix_film delivers a bang when the last frame is
reproduced,
when the movie ends bang to [1 (   and starts the others videos...also you
can bang a zero and stop the current movie.

Re: [PD] Extended View Toolkit

[Ignacio Aguirre]

Hello all

 im currently working with EWK (great tool!) for my pre grade thesis. i have
a simple question, and hope someone can help me...

 is there a way to know when the last frame from a video is played?

 im editing the ev_vid.pd patch, and putting a "print end vid $1" in the
last outlet of pix_film (it should send a bang when the movie ends) but im
not getting anything. I also try with the [end( message, but still having no
results.

 the idea is when the videos from a group ends, its automatically starts a
second group.

 Thanks for your time guys!

hope to let you know soon about mi thesis made with pd and kinect.

Re: [PD] four PS3 Eye on Mac Pro and Pd-ext and GEM

[Pagano, Patrick]

I find both OSX and ubuntu start to tweak out after 2 /dev/videos are started
I have tested this on ubuntu 10.04 with pdp_qt running 2 logitech Pro 4000 
webcams

I find much better response with multiple hauppauge cards with s-video ins
I can get 4 without squawks

I think two of those cards might draw too much power to run at the same time?  
Also, check the PCIe lane speeds and try running them at 4x or 8x rather than 
16x.

AS far as getting 4 of the same cam running, it depends on how the driver 
presents multiple cams to Quicktime.  It might show up as one device with four 
inputs, for example.  Use the 'dialog' message to check it out.

Thanx Mathieu,

I will give it a try with your tips.
I have started to install Ubuntu 10.04 on the Mac Pro and i think i will
use this OS.

In fact, i am crazy because i have installed two ATI Radeon HD 5770 on
this Mac Pro (version 5.1). Each card has 2 Mini Display Ports and 1 DVI
port. On the Apple website it is write each graphic card accept a
resolution of 2560x1600 px. When i plug 2 TV screen (HDMI and each
screen with 1280x768px) on the 2 Mini Display Port on one card (with an
adapter Mini Display Port/HDMI), it works fine. But if i use the second
card with the same configuration (so 4 TV screen on the 4 Mini Display
Port), it seems the computer have not enough power, the Finder quit each
10 second.
I use MacOSX.6.6 and this is not the lastest version (the lastest is
X.6.7 and maybe it is working with this version but now i have no time
to test this config).

With Ubuntu, the sytem start to load then the 4 screens stay black. I
have to unplug the 2 cables on one graphic card to boot normaly. So i
can only use 2 screens.

I don't know where is the problem (power ? Apple computers ?).
If someone have any experience on this problem, i will be happy to
listen him.

Now, the solution that i am going to use :
1 Mac Pro with Ubuntu and one graphic card (ATI Radeon HD 5770)
1 PC with Ubuntu and one graphic card (NVidia GT 440 or NVidia GTX 460)

Zero ;-)


My point is that it is not zero, that looking at a pile of things and saying 
that it is a pile of one or two or three is something that can be observed 
without a mathematical model, without even counting or any more elaborate 
language than these few words for these small quantities. But they have become 
so wrapped in the rest of our words for numbers that it is difficult to make the 
distinction. Think about of what words like pair mean, is pair a number? is it a 
synonym for two? or is it a directly observable quality which is quite different 
from either a single thing or a few things? Or thinking about the distinction 
between singular and plural forms of words. This is why the languages I 
mentioned are so interesting in this context.





Certainly most people can look at four matches on a table and see that
there are four, without doing any counting at all.


That's "four matches", not "the number four".  If by "number" you mean
the characteristic property of all sets of 4 elements, you're perceiving
something (the matches) which has that property, but you can't directly
perceive the property itself (i.e. its `intension'), because it's a


this is the core of what I am saying - that three or four are something other 
than  the result of counting the members of a set, and that for some unusual 
people quite surprisingly large numbers are perceived directly, independently of 
the process of counting. Occasionally the different status of these 'numbers' in 
language can be seen, they can be seen as words for some observable quality 
rather than as the first few of an infinite series of integers, used to describe 
a characteristic of sets of things.



function (in the mathematical sense) from all possible entities (let's
ignore possible worlds for now) to a truth value indicating whether or
not that entity is a set-of-four.  This view is pretty unsatisfying for
a number of reasons (for one thing, it doesn't work well for anything
other than positive integers), but I hope it suffices to show that "the
number four" can't be perceived directly.  The same sort of argument
goes for other "simple" qualities like volume, mass, density, color etc
-- this stuff has had epistemologists tearing their hair out for
centuries.  There are 2 main camps, and I'm more or less solidly in the
one that says "numbers exist" :-)


I am also in this camp, models do 'exist' in the way I use the word exist, but 
there are other ways to use this word, and so discussion gets tricky. I was 
suggesting that small counting numbers are a different kind thing to the other 
quantities listed here. They are observable in a different way, without the 
constructs that other measures require. They fit into a much narrower definition 
of exist than the others.


What I am saying about numbers is referring to your earlier remarks about pi and 
sqrt(2) in the context of discrete v continuous. Sqrt(-1) has a very practical 
and useful place in talking about physical spaces, it exists in exactly the same 
way the 1,734,834 exists. If you leave irrational numbers like sqrt(2) out of 
your model for describing lengths, and limit the non-integer numbers you talk 
about to those you can construct by divide two integers, then you get into 
trouble because those 'rational' numbers are not continuous, there are gaps 
between each one. Whether the possible values of 'length' is a continuous thing 
or a series of discrete possible values depends hugely on context, but models 
using continuous values are very useful all the same.


But I think that very small counting numbers do have a directly observable 
nature, the quantity four is recognisable without using some way of counting in 
a way that larger numbers are not. This becomes much more noticeable with the 
rare person who can just see a pile of 51 things as the same as another pile of 
51 things, and different from a pile of 52 things, without counting them or 
calculating or constructing the number in some way. The numbers here are not 
derived from counting the objects, but are some quality recognised directly in 
the pile as a whole. The words for numbers in the languages mentioned seem to 
suggest that those words may be referring to this observable quality of a group, 
rather than being part of a counting system and a way of talking about numbers 
more generally. I think I read about the person who could 'see' 52 in one of 
Oliver Sacks books, and maybe elsewhere as well.





In some languages, where mathematics hasn't become part of the language,


huh?  do you happen to know of one specifically?


I can't recall the details of the examples given, but there were a number of 
languages with this kind of counting, that is with no words to quantify sets of 
things with more than a few elemen
