Hi Wesley,
Done some more research, it has something to do with the fsaa flag. When I enable it on the Radeon X1900, the erase_color trails disappear.
Here's a patch:

have a look at the cv.jit objects.
http://www.iamas.ac.jp/~jovan02/cv/
they are built on the openCV technology.
Very usefull for tracking, shape recognition and more.
it will take some time learning how to use them if you are new to jitter but they are really worth the effort
good luck

Subject: [jitter] "prepend texture" vs "jit.gl.texture"
Message-ID: <1c81f.4700f1fd@www.cycling74.com>
Hi all,
-introduction-
I'm re-programming (restyling) a theather show for children, Farfalle/Butterflies of the italian TPO company, using a pc connected to a sensitive carpet with 12x9 pressure sensors, a dozen of proximity sensors, a infrared camera and 3 videoprojectors to create a immersive ambient.
I hope that someone can help me:
-question 1-
I've noticed that a texture created with the "prepend texture" message has a lower quality than one created by a jit.gl.texture (with the same image). I have to read the same image at the double of resolution (and more) to have the same quality.
-question 2-
With the "prepend texture" message I can delete the texture from the video memory with "deletetexture" message, how can I delete the jit.gl.texture memory? Only deleting "physically" the object?
-question 3-
How can I reproduce the "lighten" and "screen" layer's filters normally used in photo-editing software? I use many GL layers with blend_enable activated.
-question 4-
In a scene I have 48 "jit.gl.gridshape @shape plane dim 2 2" with texture (butterflies) moving around the screens with many many "drunk", "scale", "rotate", "line", etc. The movements slow down (low fps) but the cpu's graphic in the Task Manager show the cpu "relaxing".
Less GL-objects -> more fps and the cpu work more...
Why the cpu don't work well? It's a graphic card problem? I use two Radeon X1300 and a Core Duo 2 cpu.
Should be better with a javascript's programming?
-bug 1-
When I have the 3 windows in fullscreen mode in the 3 monitors and I resize the patch's windows, the borders make "garbage lines" and the windows don't resize really. I have to use the "window size xxx yyy, window exec" message or disable the fullscreen of the 3 screens.
Thanks to all
(and sorry for my english)

Do you have an example patch? I'm not really sure what you're
describing here. Are these messages to jit.gl.render? I would
recommend using jit.gl.texture for anything texture related. Also,
why do you need to worry about deleting the texture's memory? Is
there some kind of memory related issue you're coming across?
> -question 3-
> How can I reproduce the "lighten" and "screen" layer's filters normally used in photo-editing software? I use many GL layers with blend_enable activated.

You may want to render your scene to a texture and use jit.gl.slab to
do some kind of scene post processing.

use jit.gl.gridshape @displaylist 1. That should speed things up
quite a bit. Also, if you can express the patterns controlling the
gridshapes in a matrix, you may want to look at using jit.gl.multiple
for controlling the 48 gridshapes.

Again, do you have a simple example patch that reproduces this bug?
If its an interface bug, it's something that has probably been
addressed in Max5.

Hi Mattijs,
thanks for the patch. I can only speculate right now that there is
some difference in drivers between ato and nvidia causing this
problem. I could reproduce on my x1600 but my nvidia 8600 had no
problems. What erase_color with alpha is actually doing is not
erasing the color buffer and drawing a fullscreen black quad with some
blending over the scene so that it gradually disappears. I've
reproduced this effect in a shader which can be used as a drop in
replacement for cases where you're using additive blending. To use
the usuall @blend_mode 6 7 blending, you'll have to modify the shader
code a bit, but this takes care of the feedback network.

Same here, nvidia geforce 7300 has no problems, ati radeon x1900 has.

Thanks. I modified one line of the shader:
gl_FragColor = mix(framebuffer, current, erase_color.a);
And this seems to work. Thanks for the tip.
Btw what is the most convenient way to render multiple objects to the same texture? I was hoping that @capture scene could simply be applied to multiple objects, but it only seems to work with one at a time.
Mattijs
Fuzzy btw that your jxs code appears broken on the forum, luckily it is back in the textarea once I press reply.

That's a tricky one. There are 3 ways to render to texture:
1) @capture, only works for that object
2) @capture with jit.gl.sketch and multiple drawobject commands
3) use jit.gl.lua and jit.gl.begincapture/jit.gl.endcapture commands
and this made me think of another possibility that might be quite
useful for a future version of Jitter
jit.gl.texture @capture_layer . This would render all all objects
assigned to a layer to a texture. hmmm. will have to think about
this some more.

This is a very simple patch, if you load the same texture, you can test the difference. It's better if you load images with thin orizzontally or verically lines.

I need to delete the texture's memory because the show is full of hi-res images and after a bit the max's window say "error: could not allocate matrix" "error: jit.gl.texture: unable to create cache: out of memory"
In the old version of the show I've used only "prepend texture" and with the "deletetexture" I've resolved the problem, loading and deleting texture during the show.

Yes, it's "only" a interface bug and only when I have all the 3 windows in fullscreen mode.

i came across that last night after posting. Between that, and Eric Singer's Cyclops, I think i have a notion of how to progress....now it's just a matter of learning jitter/, cyclops, connecting the hardware....oh and constructing a thesis out of all this :)
are there any tutorials you know of that use the cv object?

hi everyone,
i'm not a regular contributor here on the forum, but i wanted to let you know about this:
i have a series of motion paintings on display in amsterdam from october-december using max/msp jitter. there's more detail on my website and you can schedule a viewing if you plan to be in the city at that time:

Ok, so to explicity manage jit.gl.texture's allocated memory you may
want to use javascript to delete no longer used objects. I believe
there's a freepeer() method you can use to force freeing of a JS
Jitter object. Or you can send a texture object a very small matrix
and it should adapt its internal matrix to that size. BTW, what size
images are you using and how many? Sounds like you're really maxing
out on your computer's memory.

Subject: [jitter] More motion tracking!!
Message-ID: <1c84e.4701460b@www.cycling74.com>
Yes, also I am hopping on board the train called motion tracking.
I've been fooling around with then cv.jit objects for a little while know but don't really know how to solve this problem:
I want to write a patch which registers moving objects of any color (people filmed from above) against any background. So I calculate the difference between consecutive frames.
Great, so now I've got moving people walking around as trackable blobs. But there are 2 problems:
The computer forgets about them as soon as they stop moving (they "dissapear" because the computer only sees movement): I want the computer to remember them until they start moving again.
Also, I'd like to improve the way that cv.jit.blobs.sort works: I want it to not only see how close the blobs from this frame are to the blobs from the previous one. I want it to see how close the blobs from this frame are to the EXPECTED positions of the blobs from the previous frame (taking into account their speed and direction).
I'm hoping some of you will be kind enough to give me some good pointers 'cause I'm now trying to make my own cv.jit.blobs.sort and blob-remembering algorithm in Java and quite frankly it sucks *$#@!, big time.
Thanks!

try using a jit.slide with fast up_slide and slow slide_down, ifind its
easier to work with then a other methods. it will "swallow" obejcts that
stand to long at the same spot, but tweak tweak tweak.

nice one, there is the kalman filter that deals with estimated motion,
giving you a motion vector. i may be groslly mistaken about this, maybe
someone else can be more precise. i haven't used it. but its a tricky thing
as was mentioned in a this great paper on the subject of tracking.
"
Here again there's no silver bullet. In 1995 Azuma
showed that motion prediction can help considerably, to a
point... The most basic approach is to estimate or measure
the pose derivatives and to use them to extrapolate forward
from the most recent estimate?which is already old by the
time you get to see it?to the present time. The problem is
that it's difficult to predict what the user will choose (has
chosen) to do very far in the future.
Azuma pointed out that the task is like trying to drive a
car by looking only in the rear-view mirror. The driver must
predict where the road will go, based solely on the view of
the past and knowledge of roads in general. The difficulty of
this task depends on how fast the car is going and on the
shape of the road. If the road is straight and remains so, the
task is easy. If the road twists and turns unpredictably, the
task is impossible.
www.cs.unc.edu/~tracker/media/pdf/cga02_welch_*tracking*.pdf
"
another approach is to roll your own estimated direction vector based on
last reading and one before.
combining this with jit.sort is something else, the blobs.sort object is one
of the most important in the cv.jit library for what your doing.
cv.jitauthor mentioned its not that hard to roll your own, but I'm
sceptical ;)
I'm hoping some of you will be kind enough to give me some good pointers
> 'cause I'm now trying to make my own cv.jit.blobs.sort and

search the list, try to search for methods not ideas. like if you are
looking for background removal you'll get good results by searching for
cv.jit.ravg , for example.

Subject: [jitter] Help!! Full-screen DV preview ? Need for show soon!!
Message-ID: <1c857.47015f69@www.cycling74.com>
Hi all, I need to be able to preview the live output of a DV / Firewire camera in real-time, in fullscreen, for a couple segments of a theatre show. I made a patch which does this but it's far too choppy to be useful -- Powerbook G4 is what we have to work with :(
iMovie previews much more cleanly and smoothly, but I've searched in vain on how to make the preview window go full-screen. Seems you can only see your clips fullscreen, not the live capture.
Anyone know a trick for iMovie, or another little app that will do this, or a way to optimize the preview in Jitter (don't think this will work, it was still choppy even at lowered resolution).
Don't need to record or capture, edit, anything. Just preview.
Wish we had a better computer, I'd much rather use Jitter for its flexibility, but this is what we've got.
Thanks -- replies ASAP pleeeeease!!!

I vote for @capture_layer X
Would be very nice! Doing it in jit.gl.sketch is what I normally do,
but it is clunky (hard to edit/replace commands - even with all the
abstractions available)

jit.record only allow me to record only video, so to use the mating machineone looks to tricky, it is more clean to use the grab to disk function although why i can't see the actual recording?, it will be in the future?, like imovie does?

Message-ID: <1c883.47021d3f@www.cycling74.com>
I see. So:
1) @capture, only works for that object
2) @capture with jit.gl.sketch and multiple drawobject commands
3) use jit.gl.lua and jit.gl.begincapture/jit.gl.endcapture commands
4) use to_texture with jit.gl.render
5) @capture with jit.gl.render
6) depth_grab (only for depth)
7) copy_texture with jit.gl.render
8) drawswap -> jit.matrix -> jit.gl.texture ?
Is this a complete list of available methods to render to a texture?
Maybe we can work out an example that illustrates the preferred and most reliable method of rendering a scene, capturing it to a texture and processing it with a slab.

I'm trying to get java objects to work in win xp profesional 2000, using last max 4.6.3 and jitter 4.6 so when i start max the maxwindows says basically
that it could not find java 2 runtime environment
s
o the only version in java sun that first appears in every place is java 6 update 2, i download that but max crash at launch
i heard that java change their versions name (to make everything more complex) so 6 it's really 1.6 version so i should download 1.2
i download jre- 1.2.2 and it doesn't crash though send this error
error: could nof load class 'com/cycling74/jitter/jitterobject
error could not find jitter jar
there is many many java downloads around and since i don't know nothing about java i need help to understand what i have to download to make my patch work

Hello,
Joshua's patch works great, but yes it would be handy to make the process on GPU. has anyone worked on it?
I'd do it myself but I'm still getting in touch with shaders, and it'll take a little while yet..
Thank you

hahah nice! Small world, I love Otto (hes always on tour! I miss him), and Dan Doormouse is finally warming up to me.
David is a cool guy, really into this kind of music and heavy in the motiongraphics community. Seems to randomly know everyone.
Keep in touch! Add me if you got AIM! Peace mate!

Max/MSP comes with a fisheye shader but it has not worked for me on either
Windows or a Mac machine. That being said, as an academic exercise I did
release a collection of shaders titled "shaders ahoy!" that are based on
photobooth filters which also include a fisheye shader that will offload
such processing to the GPU (obviously only if the GPU is shader-capable).
You can download the collection including example patch at
http://ico.bukvic.net/Max/
Hope this helps!

Right now, the Recipe 40:SceneWarp patch is probably the best, most
reliable example for doing texture readback of OpenGL scenes. Doing
slab processing on the output should be pretty straightforward.

I think you're missing a chunk of text. I just get a blank patch, but
a jit.window does pop up.

Thanks Andrew,
In other words: give every object in the scene a unique name and send a message 'drawobject ' for every object to one jit.gl.sketch that has @capture . Route the texture through a slab, put the output of the slab on a videoplane. All within the same render context.
Is it true that this method doesn't support the use of different layers for the various objects in a scene?
Cheers,
Mattijs

Yes, it doesn't respect layering because you're explicity telling the
objects to draw. Render to texture with groups of objects and
layering is something we're thinking about for future releases though.

Message-ID: <1c8c9.4702ac80@www.cycling74.com>
Dear all,
It is my pleasure to announce the 6th annual Spark Festival for Electronic Music and Art. Below you will find the call for works.
Site is:
http://spark.cla.umn.edu/
Call is:
http://spark.cla.umn.edu/submissions.html
---------------------------
CALL FOR ARTISTS, COMPOSERS, and PRESENTERS
Submission Deadline: 11:59pm PST, October 26, 2007 (postmarked)
The University of Minnesota West Bank Arts Quarter is proud to present the 2008 Spark Festival of Electronic Music and Art, February 26-March 2. The festival will be held on the Minneapolis campus of the University of Minnesota (USA) and neighboring Minneapolis performing arts venues, and will feature guest artists Iancu Dumitrescu, Anna-Maria Avram, Richard Devine, Paul Demarinis, and others to be announced. Starting this year, Spark is cosponsored by the University of Minnesota’s new Interdisciplinary Program in Collaborative Arts (IPCA), a new initiative that encourages and invites cross-genre works in the University arts community.
Now in its sixth year, the Spark Festival showcases the newest groundbreaking works of digital music and art. Last year's festival included innovative works by over one hundred international composers and artists, including featured guest artists Morton Subotnick, Paul Birken, and Zeitgeist. Leading scholars and technology specialists also presented papers relating to new technology and creativity. Audiences for the concerts, installations, and lectures last year totaled approximately 4,000 people and garnered multiple mentions in local and national media.
Spark invites submissions of art, dance, theater, and music works incorporating new media, including electroacoustic concert music, experimental electronica, theatrical and dance works, installations, kinetic sculpture, artbots, video, and other non- traditional genres.
Spark also invites submission of scholarly papers on Collaborative Arts, Interactivity, Cognition, Compositional and Artistic Process, Social and Ethical Issues in the Arts, Art, Music, Video, Film, Animation, Theater, Dance, Innovative Use of Technology in Education, Scientific Visualization, Virtual Reality , intermedia composition, performance, human-computer interaction, software/hardware development, aesthetics, and history and all topics related to the creation of new media art and music. For Spark 2008, we are particularly interested in papers discussing collaborative and interdisciplinary work; but submissions outside this topic are also welcome. All accepted papers will be published as part of the Spark proceedings.

Hi all,
Here is a little patch I cooked up for laughs that demonstrates a
classic rolling waves animation using OpenGL, complete with bobbing
floaters.
http://pile.pixlpa.com/patches/buoys.zip
For those that are into GLSL, the included shader makes use of the
"discard()" message to manage transparency while still using a depthbuffer.
Best,
Andrew B.

Ah.. but if you render a scene you need either layers or non-automatic rendering (banging the objects in a custom order depending on the distance to the camera).
Does the drawobject with jit.gl.sketch method allow for non-automatic rendering? I don't really see how..
Btw could it be true that the drawobject message is not documented in the html help of either jit.gl.sketch or GL Group?

jit.gl.sketch will render the objects in the order that they appear in
the list. For example,"drawobject a 0,drawobject b 0,drawobject c 0"
will render "a" first, then "b", then "c". Look in the
"object_messages" portion of the help patch. It is admittedly an
underdocumented feature, but you should be able to work it out.
Best,
Andrew B.

Is it possible?

Ah, now the puzzle is complete! Perfect, I think the time has come to rework our scene rendering system :)
Thanks a lot,

Subject: [jitter] to know what application the O.S. is focused in max
Message-ID: <1c91d.4703b8c5@www.cycling74.com>
how can i know if an external application its at the front of max? for example, i'm opening an external application from max in windows and this application goes fullscreen so if you quit you have the max patch behind but for some reason i need to make a bang when you quit the external application the issue is that i need to know when
so can i know what application its the S.O. focused on?
(like to know what application (or window) the SO is choosing by control + tab or command + tab)
thanks

Subject: [jitter] tracking motion on a mouth
Message-ID: <1c959.470405fc@www.cycling74.com>
I am creating an installation which requires me to track the motion of viewers entering the space and more specifically tracking the movement of there mouths when they move or talk. Ideally I would like to have a black bar placed over the viewers mouth when an instance occured like speaking. I have been using the some of the subtractive methods for recognizing movements but im not sure if this get's too specific to even track. The space is all white so I figure theres a chance....after all. There's always a possiblity with max right? Cheers everyone.

It won't be easy, but luckily you got cv.jit library to help you
along the way.
There you'll find cv.jit.faces object which can be of particular help.
I had one simple project where I needed to track specific parts of
the human face, so the cv.jit.faces would find the bounding box of
the face, and then using typical human face proportions would try to
locate handy points for tracking edges of the mouth, tip of the chin,
nose and eyes.
Also, try to search the list/forum for the 'cv.jit.faces', there were
some discussions about the object.

Oh I'm sorry for this.
But, with a touch of humor, I meant if he would handle some shiny,
glossy, neon-colored lipstick to the people before they enter the
space and asked them to put this on their lips, maybe it would be
easier to track the color/movement of their mouthes.
As they say on the page: "MAXalicious Naughty and Nice".

Very clever. I too thought it was some user-made patches. But once the splash page loaded and Carmen Elekrtified appeared in the toolbar I thought something was up. I will keep the lipstick in mind if I run into troubles....

Subject: [jitter] IR tracking
Message-ID: <985233.99245.qm@web30915.mail.mud.yahoo.com>
Greetings Folks
I am working on a project that involves tracking IR LED's used as markers -
one issue is that an LED is not real large -particularly at a distance - so I am working on creating a larger marker...
In my testing with cv.jit.track and jit.findbounds (tutorial 25) the CV object loses the VERY small led much more easily than the findbounds...
I did try using the cv.jit.dilate object as a precursor to the cv.jit.track object in hopes of making my object bigger and thus easier to track...
I was hoping to us the cv.jit object due to the ability to track several objects - particularly ones that come through the same color...
any ideas with this one?
thanks
jamie

Message-ID: <1c9eb.4705687a@www.cycling74.com>
I'm trying to transition over to the use of jit.vcr rather than jit.record for recording the output of my patches because I'd like to record the sound aspect of the jit.qt.movie object as well as the video (in sync). I'm having trouble doing this. Using the method I had in place for the jit.record, jit.vcr only records one frame of video with no sound. I've included this patch. Any help is much appreciated (my trial runs out tomorrow, and I'd like to finish this up before then). Thanks!

sorry - I didn't think it mattered as I had not really gone very far - but here's all the info
as I mentioned I was looking at cv.jit.track and then tried making the tracked object bigger using cv.jit.dilate before tracking with the cv.jit.track
I'm finding that jit.findbounds works better - I can post that patch as well if it would be helpful
I'm on a 2.4 Ghz macbook pro, 4 gigs of ram, jit 1.6.3, max 4.6.3, OS 10.4.10, quicktime 7.1.6,
thanks for any thoughts...
essentially just a simple hack of the help files as follows:

Don't use cv.jit.track for these situations. Use cv.jit.label + cv.jit.blobs.centroids or cv.jit.blobs.bounds. cv.jit.blobs.bounds in particular works essentially like jit.findbounds but can track several objects at the same time.

Hello again
I tried using cv.jit.label but it sees the background as one large blob.. and does not see the two small points
any suggestions - I'm just working with the help file - no mods...
thanks

You need to process the image before sending it to cv.jit.label. If you are tracking LEDs than I assume they show up as bright spots. Your object sequence would then be something like:
[jit.qt.grab]->[jit.rgb2luma]->[jit.op @op >]->[cv.jit.label @charmode 1]
The cv.jit.blobs.bounds helpfile is built this way. You need, of course, to provide jit.op with the proper threshold value. If it picks up the whole backgound, then your threshold value is too low.

sorry for late answering , a place you may want to have a look at is the Musical Gesture Project at the university of Oslo, norway.
http://www.hf.uio.no/imv/forskning/forskningsprosjekter/musicalgestures/
it might be good place to look at for your thesis research, get inspiration . there are some patches, applications to download for motion analysis >software>Musical Gesture Toolbox.
good luck

CV objects also have threshold value argument (default 20). Try changing the value.

Hi.
I am displaying 4 small videos on the same screen.
Each one is on a jit.gl.videoplane
Each video have a scrolling text. The image is running fine, but the text is not running smooth at all, kind of jumping...
Is there anyone who know where this can come from?
The video is running perfectly when i play it in the quicktime player, i only have this problem when i play it from Jitter.....
Many Thanks.

these things look fantastic. I am looking at what kind of cameras to use for this project. If I'm tracking 3 dancers in the xyz system, it seems for these systems, it's ideal to use two cameras: one pointing down (to get xy) and a forward facing camera to record the xz plane. Systems that rely on sensors seem to be prohibitively expensive.
thanks for the great advice again!

Subject: [jitter] Jitter + Macbook Pro => ATI or Nvidia
Message-ID: <1ca7e.4706a1db@www.cycling74.com>
Hello
I as much as possible use the GPU resources in my Jitter patches.
Which is the best on the graphics choice of board to use with Jitter, and to exploit the resources Open GL as well as possible (like slab and other shader…). ??
ATI Radeon X 1600 /256 Mo
Nvidia 8600M GT /256 Mo
According to an article seen on the site
http://www.configmac.com/actu/article31.html
“on Macbook Pro, the graphics board replacing of ATI X 1600 on is
a NvidiaGeForce 8600M GT with 256 Mo of SDRAM:
more powerful with Quartz, but much less with OpenGL according to the application Xbench 1.3”
Is it necessary to prefer?
Macbook pro 2.33 GHz + ATI Radeon X 1600 /256 Mo
or Macbook pro 2.4GHz + Nvidia 8600M GT /256 Mo_
For best exploitation GPU and returned of Jitter
ATI or Nvidia. ?
Would you have an opinion?
Thank you for your councils

I profiled this benchmark with OpenGL profiler. Essentially it's
measuring a few functions:
glCallLists along with rotate, scale, and translate and push/pop
matrix. A better test would use vertex buffers and shaders to measure
memory performance and fill rate. I wouldn't trust this test for very
much. As a counter example to this test, I found a 300% increase in
using vertex buffers over display lists with large models. Modern
cards are tuned for buffer objects, not atomic opengl calls like this
test carries out.
GeForce 8600 GT
Stream Processors 32
Core Clock (MHz) 540
Shader Clock (MHz) 1180
Memory Clock (MHz) 700
Memory Amount 256MB GDDR3
Memory Interface 128-bit
Memory Bandwidth (GB/sec) 22.4
Texture Fill Rate (billion/sec) 8.6
ATI doesn't publish comparable specs so its hard to do a 1:1
comparison. Major limiting factors for 3d graphics and GPU video
processing are texture fill rate. Many things are fill rate bound.
Shader architecture is also important. The ATI and NVIDIA cards have
completely different architectures. The ATI card has a fixed
architecture with dedicated vertex and fragment shaders. The NVIDIA
card has a flexible architecture where depending on what operation is
being done a shader until will operate as a vertex, geomety, or
fragment shader. The other major difference is that the 8600 supports
shader model 4.0 and the ATI only supports 3.0. This means that the
NVIDIA card can do geometry shaders which will be incorporated in a
future version of Jitter. The things allow for geometry instantiation
on the GPU among other things.

BTW,
I personally went for the 8600. I'm not sure how it compares to the
x1600 in a fair head to head test, but I suspect that if they are
comparable now, there will be improvements over time as the card is
new and driver updates can give significant speed improvements as I
have a hunch will be the case when Leopard comes out. But that is a
hunch so I could very well be wrong.

I don't have any specific numbers to quote, but I've found empirically
that the 8600 seems to be a much better performing card for my uses,
which typically involves heavy vertex and fragment shading and large
numbers of vertices. Bear in mind that my experience is pretty limited
with the ATI card, and there were probably other limiting factors. I
personally opted for the NVidia card. The support for geometry shaders
will probably also be a big deal to you at some point if you are into
OpenGL now. (coming to a future version of Jitter, I hear)
Another thing of note with the newer model MacBook Pro is the increased
resolution of the built-in iSight.
YMMV,
Andrew B.

You can't really do it in a shader. You can normalize on a per-pixel
basis i.e. a vector normalization. If you want to normalize planes,
you need some kind of histogram function which doesn't really exist in
a shader. scalebias is the closest shader to jit.normalize.

the thing with scalebias is it does not adjust its
