ARImageReference rectangular image support

When creating an ARImageReference for ARKit, you specify two dimensions for the physical size ( see https://developer.apple.com/documentation/arkit/arreferenceimage/2941027-physicalsize, and https://developer.apple.com/documentation/coregraphics/cgsize )

Unity only allows you to enter one physical size, and so assumes the image is square. As most images are rectangular, this imposes quite a constraint on the detection.

Are there any plans to enable the entry of both sizes ( or at least identify if the physical size entered is for the length or height of the image, and the other value gets calculated based on the aspect of the source image ).

 

@Mal_Duffin Hey are you able to rotate and zoom in the Augmented objects?

 

You enter the smaller physical dimension and using the aspect ratio of the image, XCode deduces the larger dimension. See https://developer.apple.com/documentation/arkit/arreferenceimage/2942251-init

 

Thanks for the info jimmya!
