The software doesn’t care what rez you are running your projector at, but it is important to configuer your mesh at the right resolution.

So: when you are configuring your mesh, make sure your projector is in 1280×720 (or whatever rez you want to work at). then do the mesh config stuff (ie project the white mesh full screen, then drag all your camera mesh points so they match).

Then check with the test view, and if the blobs line up you should be good to go.

(with a few caveats: some of the more complicated flash apps use the touchlib config files to calibrate themselves. BBTouch has a similar thing, but it is a totally different file, so you would need to rewrite that part of the code in the flash app.)

Also note: the TUIO information that BBTouch is generating presumes that the TUIO client app is running fullscreen, so if you aren’t running fullscreen you will need to account for that (ie convert the fullscreen TUIO coordinates to your current window)

Quick question: which flash apps are you using?

Also: about the screen going white: Yeah, that is a known issue. If you ‘Go Fullscreen’ on a view while another view is already fullcsreen, there is no way to get it back, and strangeness can occur :-)

Cheers!

thank you very much for coding this piece of really cool software!
I chose this one for my table, because i think the blob-detection is better than other available.
But, for which resolution ist the software optimized? My blobs detected and shown at BBTouch are OK, when sent to an Flash-Application, there is a offset of ca. 5cm(ca. 2inches). My HDMI-beamer shows native 1280×720, i switched already to 1024×768, but there seems to be no better result. Do you´ve a tip for this effect?
One hint: There are a few error, when changing the views around, then the screen is only white.

yeah, I think the way I am using the sequence grabber doesnt like those ‘non standard’ cams. I will have a look at those drivers. I may need to use the QTCaptureKit in the cases like those where the SG doesn’t work with them.

Thanks for the head’s up! (I updated the guide to mention those cams)

Cheers!

Great to see a quick guide. I have a few problems you might be interested in? (not that sort!)

Right it appears BBtouch doesn’t like Macam’s Drivers http://webcam-osx.sourceforge.net/ heres the link.

This is the only way i can get the two of the three obscure web cams to work with os x at all. i’ll list the crappy little lot:

Mikomi Typhoon
Logitech Quickcam express
Technika VGA RUBBISH! (doesn’t work with os x at all!)

These are all USB Web Cams.

I also use my much nicer Sony DCR-TRV20E DV cam which would be perfect if it wasn’t for the lack of constent power supply (ie not recharging the one battery!) and dodgy focus as its quite battered! Also auto power off which is factory set and not stopable even by winding a tape to the end a good trick with other handhelds.

Ultimately none of this will be a problem once the FireflyMV arives.

The reason i mention the macam usb problem is simply that others may want to use usb web cams? Have you experianced this?

Symptoms include grey blocky camera screen in BBtouch at a res of 640×480 and frequent crashes when changing to a lower res. For me USB web cams do not work.

Anyway thanks for a great little app cant wait for more from the Panda!
