Hi,
I've been searching for a solution and tried tips and trix in your documentation but can't get my model to stand still on the target.
My target has a 5 start rating but it doesn't seem to matter. My code is based on the Android example code and I'm using the Java version with ImageTarget and rendering i OpenGL ES.
May it be something wrong with the model and is there something I can do about this?
I'm attaching a video recording where this problem is very obvious. It seems to jitter more when moving the phone. The distance to target is about 1.5m and it doesn't matter if I use extended tracking. The phone I use in this example is LG G3 but I've tried a Samsung Note 4 as well as a Nexus 5.
Am I missing something here?

Jittery model on image target
Finally I can reply on the forum :)
So I tested with the stones target and got kind of the same problems. I'll attach a video of this as well.

From the video it appears that the distance to the target is making the target appear a little bit small in the camera view, which is probably part of the reason for the jitter.
The relatively large 3D model (compared to the target size) is then making the jitter much more noticeable.

Yes we are using continous autofocus at the moment and "unforunately" we will be showing large models. 4-5 times bigger than the one I used in the videos.

Sounds like yes. If you already tried Extended Tracking, and autofocus options, and if you really need to display very large 3D models (compared to the target size), applying some filters to smooth out the jitter is probably your best option.

Thanks for your help guys.
We have applied averaging of a pre defined amount of frames/matrices in a buffer and are trying to remove matrices that stand out compared to the previous one returned from vuforia.
