that's just cool! ...bravo!

I haven't released it yet, because of a few issue, managing gem images, using latest version, ...

what problems are you having? will you release the external as GPL?

If my sourcecode of pix_artoolkit is useful for the artoolkitplus external, I will joint the davide morell's work for pd-gem.

well, I don't see why we should restart an already done job! looks like your external is working fine, no?

ciao, Davide.

hello,

i was waiting to see if more people would show an interest in this project. i can't believe how much the traffic is low for a technology that will be everywhere in a near future (forums on ar).

anyway the good news is that james tittle is interested in this project and davide morelli already did a big part. we just need the source of pix_artoolkit write by shigeyuki for max/msp. we will port it to pd and then we will try to use artoolkitplus!

shigeyuki can you share your source?

maybe other developers will be interested in joining this effort to bring augmented reality to a dataflow environment. that's why i still cc gem-dev and artoolkit forums.

I'll be following closely Morelli's work and altough right now I didn't really put any of my code available, I'll do it pbly in january when it is a bit more advanced.

I didn't write anything really useful, it was just a dummy gem external that should use the GEM chain to feed the artoolkitplus markers detection function. it doesn't output any position matrix, any marker list.. I hope I can find some time to try to use latest artoolkit release..

ciao, davide.

hello,

i apologize to respond late. my machine i develop gem4max has a trouble to access sourceforge.net. i uploaded the source of pix_artoolkit

http://www.kyoto-su.ac.jp/~hirai/max/pix_artoolkit.zip

thanks, i've added the object to the regular Gem.

and also upload an archive file including code warrior project and examples.

http://www.kyoto-su.ac.jp/~hirai/max/pix_artoolkit.dmg

unfortunately i don't know how to use this here (on linux) so i have no idea, whether the code works or not (at least it does not crash).

i removed the calls to argInit() (which removed the dependency to ARgsub (and glut)). so know, Gem only needs to link against libAR.a

ah yes, [pix_artoolkit] will only be available if configure can find the ARToolKit libs.

please download them.

thanks,

neat! thank you shigeyuki, thank you very much for sharing your work! also big up to IOhannes for putting pix_artoolkit in cvs of gem. it compile fine and can loadcpara:

[pix_artoolkit]: ARToolKit support by Shigeyuki Hirai [pix_artoolkit]: loaded camera parameter file:(/me/camera_para.dat)

the only thing is not working is loading a marker: error: [pix_artoolkit]: can't set marker number 0

MAX_OBJECTS is define in pix_artoolkit.h to 16

void pix_artoolkit :: loadmarkerMess(t_int n, t_symbol *marker_filename) { if (n > MAX_OBJECTS || n <= 0) { error("can't set marker number %d", n); return; } if ((m_object[n - 1].patt_id = ::arLoadPatt(marker_filename->s_name)) < 0) { error("ARToolKit: pattern load error (%d) !!", m_object[n - 1].patt_id); return; } post("loaded a marker file (%s) as %d...", marker_filename->s_name, n); m_object[n].patt_name = marker_filename; }

is there an error here?

no the error is in class_addmethod(): pd does not allow to have messages of with arguments "<float> <symbol>" automatically typechecked (the reverse "<symbol> <float>" works fine). i have changed that to use A_GIMME but have forgotten to check it in...should be fixed now. it should appear in the anonymous CVS soon (in the meantime, just download it from the webCVS interface)

we are close!

we'll see...

hi!

it's working: i can load a marker: [pix_artoolkit]: loaded a marker file (/me/patt.hiro) as 1...

now i think that gem for max/msp is working with pixels? take a look at the output of the second outlet of pix_artoolkit:

draw_particles1: -208.106 -143.641 961.829 0.644829 0.131227 0.140218 42.285 draw_particles1: -208.106 -143.641 961.829 0.644829 0.131227 0.140218 42.285 draw_particles1: -208.106 -143.641 961.829 0.644829 0.131227 0.140218 42.285

am i wrong?

afaics, the values you get are directly taken from ARToolKit. probably they are normalized to fit within their glsub-rendering system (for easy use). it should have nothing to do with pixels.

btw, where does "draw_particles1" come from? is this just your [print] or some memory corruption?
