Unstable objects using osgART
Reply with quote

Hi Everyone,

I'm testing my first app using osgART but I'm not getting the results I hope for. The object that I render on top of my marker is shaking a little bit. Even when both the marker and camera are completely still! Any ARToolKit only application works like a charm, the object stands still on top of the marker as it should. OSG only applications are also ok.
I tried using TransformFilterCallback but the result was a very slow response tracking, i.e. I moved the marker and the cube moved a lot slower until it matched the marker again. I messed around with the parameters but couldn't get to a satisfying result.

Btw, I'm running the osgartsimple example and it presents the same strange behavior.
What am I missing here?

Any suggestions?

Thank you in advance.

Cheers,
Theo

Hello,

I realize I'm bumping a 7 month old post, but I'd like some answers to be here for anyone looking!

ARToolkit has a history function that can smooth out some jumpiness at a slight loss of accuracy. (Very slight in my small experience).

Take a look at this page for some info: http://www.hitl.washington.edu/artoolkit/documentation/tutorialhistory.htm

Then you'll need to make a simple edit to the artoolkit plugin project in the osgART solution. (The line is there, it's just commented!) Build it again and build the "install" project.

Good luck,
Elliott
