Thanks to Eric and to weasley who reported the solution he found.
I spent an entire day in trying to understand why everything was working nicely on my PC but not with my web site and I finally understood.

What am I supposed to do with the source code you provide? I removed everything that had to do with squareContainer and squareShape and instead copied the lines in this page. My webcam is working and the marker is detected, but no circle appears. Could you help me? Thanks!

@Eric: Thank you much! I found the problem and have fixed it. My old IISA server would not deal with the .pat, .dat or .dae files because the MIME type was unknown. Here’s a Microsoft link with more info in case anyone else is running into similar problems:

Couldn’t have solved it without your recommendation for using LiveHTTPHeaders.

Eric, Thank you for the suggestion. Before I got your response, I discovered that video works when I uncomment the source video line “this.addChild(this.video);” in the camera source file. I get a mirror image of the video, better than no video at all when the line is commented out. The markers aren’t found, but it’s progress.

With LiveHTTPHeaders running, it’s reporting 404 Not Found errors on the cameral parameters and pattern files, files that I can see in the directory structure on the site where the URL says they should be?! I copied the entire blasted project folder to the server in my mad attempt to make sure nothing was missing, yet still am having trouble.

Thanks again for your help and suggestions.

@weasley: most likely you didn’t upload all of the resources files that FLARManager/Toolkit needs to load at runtime. try running in Safari with your Activity window open, or in Firefox with LiveHTTPHeaders running, to see what’s not getting loaded.

Thanks for the great tutorials and well commented code. Unfortunately, I’m having trouble figuring out why the FLARManager examples work great locally but the video fails to display when I run them from my website and no markers appear to be detected. If anyone has any suggestions, I’d appreciate them. I’m relearning programming after working with p-system pascal in a former life and so I may be missing something obvious.

I just noticed that (at least in my svn downloaded src) for the FLARManagerTutorial_3D that the FLARPVGeomUtils were not found as the import was missing the .geom part of the path.

The src I had said: import com.transmote.flar.utils.FLARPVGeomUtils;
But needs to be: import com.transmote.flar.utils.geom.FLARPVGeomUtils;

Just a little thing.

Thanks for the tutorials and examples.

@stuart: I was trying the very same thing, and now have it working. E-mail me for the source. It will be on my blog soon, fingerpuk.tumblr.com . The reason you are getting your errors could be because FLARManager is seeing markers but your switch doesn’t reference them.

Hello. I didn’t know that, but do now However, is there a way to pass these values to TweenMax simply? I’m not great at AS3 at all, still learning a lot. I think I’m almost there, I can use the switch to get my marker id, convert that o the string value of my movieclip, but then I get odd errors when trying to pass that to TweenMax. I think maybe it’s a display object issue as it’s buggering up on rotationZ.
