Great Work Guys! Conratulations!

It is running very smooth and fine on my Intel MacMini (the newest one with 2GB ram, osx 10.5.5).

Just a few things i noticed:

- would be usefull to be able to change the camera resolution (without editing the XML file)
- adding/deleting horizontal points for calibration (shif/+/-) is messed up - no matter what i am doing i can only add or delete points for the vertical axis
- it would be usefull to manipulate the minimal moving distance for blobs (right now they are very sensitive - even if you don’t move your fingers, the blobs a shaking around slightly)
- i noticed that the FLOSC client terminates with a java error after using it a while (tbeta is still running and sending TUIO messages and i can run our native TUIO compatible OSX-MT apps) - is there an overflow problem? I am not sure but i think this happens when more then 6-7 fingers are touching the surface simultanously…

Keep up the good work! Amazing results what you have achieved allready…

Cheers!

Hello sandor,

to adding/deleting y points for calibration you use “shift"&"=" or “shift"& “-” (its the minus from the numberpad) this works for German keyboards.

(it took me a lot of trial and error to get it :-( )

The Problem with the hanging of the application seems to be a osc bug . I’m in contact with cerupcat and told him the issue. He will fix it as soon as possible.

Cheers from near cologne

@ M. van Veen: Yeah, you can’t use the CMU driver with tbeta as it’s not supported. But, the good thing is, the directshow driver for tbeta is just as fast as the CMU driver. So go back and use the normal driver that came with your fire-i and it’ll work.

@ sandor:
* the editing of camera resolution/fps in the config.xml file is temporary, it’ll eventually be within the interface. Are goal is to have no editing of the config since that’s annoying heh.
* As for adding y-axis points, make sure you’re holding shift as mentioned above. I don’t have a mac, so let me know if it’s a mac only issue. I’ll probably change it so hotkeys aren’t used and buttons are instead. If you can’t get it working, you can go into the calibration.xml file and change the GRID X/Y manually before starting.
* Also, as mentioned above, I’m working on a fix for the OSC issue. I think I may have it worked out and will have a new release up very shortly. It’s hard to get every request/feature in a first release; especially a beta release. smile We have many small additions that’ll be added in for performance and easier use.

UPDATE: I fixed the OSC issue. An error on my part. Now it sends without crashing and is about 4 times faster smile I’ll have new bins up probably tomorrow.

TomT, you can add as many photos as you’d like. Just add photos to the images folder and then in the images xml file, add the name of the photo. Same goes for the videos.

Thx Cerupcat, i´ll test it immediately.

I looked for the AppLoader and found one. But at the packete is only a AppLoader.exe for Windows. Does anyone know this application alreday compiled as .swf, so it does work for Mac, too? Or a AppLoader.app?

Just trying to get this working on os x with a fireflymv.  Touche and BBtouch work fine with no extra drivers needed!  Any thoughts on why tbeta doesn’t like the firefly?

Cheers!

ajlovegrove, I’m not sure about the firefly right now.

We’re using the openframeworks library, there’s a post about the firefly on mac here: http://www.openframeworks.cc/forum/viewtopic.php?t=439&postdays=0&postorder=asc&highlight=firefly&start=30

I don’t have time to take a look at every individual bug right now, so if there are camera issues, I would recommend helping me out and going through the openframeworks forum first since camera issues are really an openframeworks issue, not a tbeta issue directly. If you find helpful info, let me know and I can try it out. When I get a chance i’ll see what I can do. I don’t have a firefly camera so it’s not the easiest thing to test.

The source will be out soon and then you’re free to adapt to your needs while we work on the addon/lib.

How soon is soon? smile

Ok thanks.  I know it not easy when everyone is clamering for your attention!  I will check the open frameworks for the firewire cam stuff.

Cheers

To got the firefly mv work, you have to install the PGR FlyStream Driver, maybe you have to install it manualy thru the xp harware manager if the driverControlGUI from PGR fails. The flystream driver supports directshow witch is needed for openframeworks.

Currently our firefly only works at 14 to 16 Fps, depending on the resulution. If anyone have an idea to got this work with higher framerates please let me know.

Awesome application, I love the simplicity and ease of use.

Everything seems to work ok. I haven’t tried calibration though, because I just made a quick mtmini. However, the GPU mode doesn’t work, the filters and tracked image just goes blank.
CPU usage is around 22%.
The camera framerate will sometimes drop low, 9ish fps, but stays at around 15fps. (Cheap USB cam).

My PC specs:
CPU: Athlon 64 X2 4800+ Skt939 Toledo @ 2.4Ghz
Motherboard: Asus A8V-E SE
VidCard(s): BFG 9800GTX 512MB PCI-E; eVGA 6200 PCI (Secondary)
Mem: Corsair 2x1 gb TWINX C2 PT XMS
HardDrive: Western Digital 8m Cache 250GB 7200RPM
Monitor(s): 2x CRT 17” Phillips 107B5/107T6 and LCD 22"wide Samsung 226BW (Triple Display)
