hi martin,
sorry i was wrong in stating that i was using:
pd-extended 41.4 release on osx 10.6.2
I am actually using the latest autobuild off hans site.... so:
Pd version 0.42.5-extended GEM: ver: 0.92.1
with this version of extended i get:
[pix_artoolkit]: ARToolKit support by Shigeyuki Hirai
when loading pix_artoolkit rather than:
error: [pix_artoolkit]: compiled without ARToolKit support!
on extended 0.41.4 so im assuming something was fixed (obviously :) maybe from out of the last discussion from last year? i cant find thread because it seems like the list is down again...
your on linux no?
its right outlet), I'd be interested in what camera,
ah... built in isight..
i left the printed hiro test pattern at the uni so ill give you some data printouts tomorrow morn when i get in...
I will take a look at your new patch you sent too!
Thanks! mark

now I compiled the current gem release 0.92.1 from sourceforge (I could not find pix_artoolkit in svn)
it contains some changes compared to my older version of pix_artoolkit source code, but unfortunately again no markers are recognized with my setup (pix_artoolkit does't output anything on its right outlet.)
I also had a look at the "cube" part of the help patch you sent me and also the sources of pix_artoolkit. It seems it outputs 7 values which are: the translation (position) as a vector x y z, an other vector 'x y z' which is the direction of the detected rotation axis (the "rotation normal") and a rotation angle around this axis. so the "draw cube" part of your help patch should work just fine if everything else (marker detection, marker recognition) works. maybe the size of the cube (40) is too big to see anything or the cube is only drawn behind the video. i changed that, see attachment.
when i was working with tracking data in general I scaled everything to usual gem units, so that for example a desired range of 0 to 40 cm went from 0 to 4. so it fits in the usual gemwin for quick tests.
I have no idea which units the external will output - choose a smaller size for the marker than 80, until you can see something useful.
my assumptions about the output of pix_artoolkit from yesterday are completely wrong (there's no matrix output) - so the patch I sent you before is pretty useless - sorry for that.
if pix_artoolkit is working for you (outputting anything on its right outlet), I'd be interested in what camera, resolution, version of Gem you are using. Some output of the external would also help me improving the help patch - if necessary.
cheers martin
