Hi there from the MFADT class!
Awesome ideas & executions in these projects. I really want to learn more about pv3d and other AS related stuff from you.

Hi Chaco, here’s some pseudocode:

function onEnterFrame(e:*)
{
if (_webcam.activityLevel < 25) return;

var b:Boolean = _flarDetector.detectMarkerLite(_flarRaster, 80);
// etc.
}

great idea please in the meanwhile can you explain more about this. do you mean that if there is no activity you put some kind of delay in the detecMarker function?

[Because in this demo the camera is assumed to remain stationary for the most part, I’m doing a simple check of the webcam’s activityLevel, and if it’s below a certain value I skip telling FLAR to do a detectMarker, which is where most of the performance hit comes from.]

Thanks a lot for your comment! I’m looking forward to your code. Don’t rush with it :-)

Pipo, I’ve greatly simplified the algorithm for the snapshot part which allows it to be applied to any kind of mesh, not just to a plane or cube face, and hope to post a demo and the code for it soon. (I’ve really wanted to do this sooner but have lacked the necessary alignment of time + energy.)

Because in this demo the camera is assumed to remain stationary for the most part, I’m doing a simple check of the webcam’s activityLevel, and if it’s below a certain value I skip telling FLAR to do a detectMarker, which is where most of the performance hit comes from.

Could you please explain how to take a snapshot of a particular area and to use it as BitmapMaterial for example on a Cube?

How do you got such a good performance? :-)
