I've been working on [tkwidgets/text] but it's still a bit buggy.

I am not really a fan of svn:externals and before we start using them
a lot, we really need to look at the issues. Thomas' system has been
working for years. If it ain't broke, don't fix it :).

hi,
i think pd-dev people should remove externals/grill and like pdmtl / gridflow checkout your svn. it will avoid many questions about flext not being updated and such.
but i can't checkout your svn. i think you need to permit anonymous checkout. pat

Here is a dll of Frank's moogladder~ v.02 compiled against pd 0.40_2 The code should go in svn somewhere. ( I replaced 2*M_PI in the code with TWO_PI to avoid a multiply (compiler optimisation maybe does that already)).
Thanks, Martin!
Out of curiosity - what compiler did you use? I've never compiled externals on win xp but would like to learn how. Is it possible to use the free version of MS Developer Studio? Other alternatives?
I'd like to try to make a stereo version of moogladder~ and also try tanh optimizations to reduce the cpu load.

I now made a version where cutoff and resonance are signals. This version is a bit more CPU intensive now, as some computations had to move into the DSP loop to react to the changes in center frequency.
Awesome! To my ears it sounds great - very close to the Csound-version.
I played a bit with a rational tanh approximation from the music-dsp list but it didn't sound good anymore. If someone wants to play with other approximations e.g. table lookup: Just change the function "mytanh".
Some optimizations are needed for reducing cpu load, true, I'll look into it.
The filter response gets nasty and loud if the center frequency is near or above the sampling rate. Maybe it should be restricted as well. But then, resonance at 1 will make everyone jump, too...
Yeah I noticed that aswell. I think the Csound-version has cutoff restricted to 0...1, which is 0...11050 in hertz.
Thanks again.

Only resonance is restricted to 0 and 1. It is in the pd version as well. I made some tests now and it seems it's not the cutoff frequency alone that makes the filter run wild. With resonance set to 0 a cutoff of 96kHz when running at SR = 48kHz doesn't go wild. But set resonance to 0.1 and it runs away.
So in the end I'd say, just be careful and if in doubt [clip~] your input values.
Another issue may be denormalization, so some PD_BIG_OR_SMALL checks could be useful.

Did you define that yourself? My math.h doesn't have TWO_PI ...

i posted this a few days ago i guess it didn't came through...
hi i just got 2 logitech webcams at once running & started playing around with them. my curiosity is orbiting around computer stereo vision & construction of depth. is anyone experienced with things like binocular disparity algorythm for stereo vision & might have some recommendations? as far as my nose dipped into research there's nothing within pds extensions?! thanks for hints & salutis olsen

i think olson wants to do the opposite: take a stereo-image of the
real-world (with two cameras) and try to somehow get a "model" of this
real-world into softworld; rather than synthesizing a pseudo-3d visual
of a virtual world.
simon: you are right, color-separated anaglyph images are currently
done in red/green, and if you want to change that you would have to
recompile Gem.
i think this is an issue that should be solved; but then, i also think
that rather few people really use this feature, and if they do so they
are probably up to do the compilation stuff; at least nobody has yet
complained are filed a feature-request.
olaf: seems like there are no computer-vision experts around here; at
least i am not one of them; this might explain the lack of answers to
your original mail (which at least i received)

Hi IOhannes, any tips on where to change this? I can only find red/blue glasses here in town (maybe I could add a 4th mode for red/blue rather than red/green rather than replacing it so everyone can be happy?) Best Luke

O, just saw the "stereoSep" etc. messages, probably better to do it that way, like stereoColor 0/1 for redgreen/redblue or something

even cooler would be a way to specify the colormask via messages, so people can use any other combination they come across.
anyhow, the relevant code is in Base/GemMan.cpp:714-715 where you can shose which colormask to apply for the 2 views (0=red, 1=green, 2=blue).
however, on the (not so) long run this should be moved to abstractions
