Hello,
i try to make a connection between 2 numeric cameras and pd by wifi.
My idea is to get the picture from the camera in jpeg format into pd
"live and direct".
After i'll want to put some effect and then screen a picture made from
2 different sources.
Is there a lib that give that kind of work

I personally use a GK-3 (which really is the same as the GK-2) a wired my
own 13-pin to siz 1.4" jacks, which go straight into a Hammerfall Multiface.
The individual signals are quite but not unusably so, maybe around -30 dB
from full amplitude. That works pretty well.

thanks, cyrille, I did not know unpack~. also using "until" to loop 64
times at once (in the same logical time) is much easier coding. and
since one vector of 64 samples is always seen as one unit, this should
not make a difference in cpu load distribution.

The log is necessary to keep the distribution normal, and the range is

As is unfortunately often the case, I'm getting utility from something

Actually, it makes more sense for U1 to be distributed on [0, 1)
Because we need to take Z to be a finite n
Here's a histogram generator (binner) that shows the distribution of

Ah, here's a missing factor of 2 in the exponent. That should be
g(r)= 1/sigma^2 * e^-(r^2/ ( 2*sigma^2) )
And the correct formulae are
x=r*cos(theta) = sigma * sqrt(-2 * l
Wow, that's a gorgeous demonstraton Martin!
Everything becomes clear as time -> infinity :)
And somehow our little Earthling brains are able to
spot this signature distribution as we listen to rainfall.
Now I'm getting how uniform fall leads to

One thing I've been thinking of lately for pd is to synthesize a
impulse train with the poisson process. Many natural phenomena, like
the timing of rain drops, can be simulated with the poisson process.
It's just one of those ubitquitous relations that pops up everywhere.
