Vuforia SDK Version: 4.3.2 -
Description with steps to reproduce:
The tracking quality (Vuforia 4.3.2) is very poor compared to old Vuforia (Version 2.8.7). I have worked with a "Multi Target".
In the past in Vuforia 2.8.7 (and Unity 4.0) this Multi Target was very stable! There was a huge quality improvement from Vuforia Version 2.0 to 2.8! We could place the iPad on the table and there was no jittering motion anymore.
now, I recreated the Multi-Target online again (same images as in old Vuforia Multi Target), downloaded it as unity package and used it in Unity 4.6.5 and Vuforia 4.3.2: It works not very good anymore. Always jittering. I have found out that video stream looks more zoomed in than in the older vuforia version.
I have both apps on our iPa4. The old app works still perfectly compared with the new vuforia.
Tested on iPad Mini (2), iPad Air, iPad4 (Retina) and iPhone 5.
The worst tracking quality we had on iPad4 - here the video stream looks very zoomed in compared to the older Vuforia version.
why does this happen?
Development OS (Mac OS X, Windows, Linux): IOS 10.1 -
Mobile OS and Version: Apple IOS 8.3 -
Mobile Device Manufacturer and Model name: Apple iPad Mini (2), iPad Air, iPad4 (Retina) and iPhone 5. -
Do the Vuforia Sample Applications show the same behavior?: yes. but it cannot be recognized so easy because in our case the marker has a size of 2 meter x 1 meter. with such a big marker you can see every jitter very easy.
