Vuforia and the new iPad

By garyriches on Wed, 06/20/2012 - 17:11
Hi guys, this bridges Unity and iOS but as its on iPad I thought I'd post it here. I have an AR project that is swapping real life images for virtual images and on 3GS, iPhone 4S and iPad 2 it's all fine and the images replace perfectly but on the iPad 3 the image I map over the top is slightly smaller than the real life image I replace so you can see it's edges under the AR image I add. I am using the latest Vurforia version for Unity and an iPad 3 on iOS 5.1.

Can you clarify "swapping real life images for virtual images"? Do you mean you have an OpenGL rectangle that covers the trackable on which you paint another image as a texture? And on the iPad3 the calculations you make for the size of that rectangle come out smaller than the visible target?

In the simplest terms lets say you have a map in real life and the same map as an image. You have the map as an image as an AR target and have a plane mapped to exactly the same size as the target (don't forget this in in Unity so you can see the plane) that has the map texture also. The expected

Hi Gary, I've just tried this same test on a native implementation and I see the same effect. This may be due to our iPad3 camera calibration - we will look further into it. Thanks for raising the issue. :-)

No worries in terms of any updates from you guys will they be in this thread, a more general manner or both? Thanks.
