The EU AI act doesn’t force C2PA or any particular standard. Yes many people will use C2PA erroneously, but C2PA is not meant for indicating content was virtually generated, but that it was not modified from origination. C2PA is fallible if your origin is fallible. SynthID is a better standard for designating something was created with GenAI, though is limited in what it covers. For example, 3D content is currently a poor fit for both SynthID and C2PA. Audio is also imho poorly served. There are a few things in the works for 3D…audio is an area I’ve tracked less. Wacom have a synthid like embedding for geometric data https://youtu.be/AEi083BtgvU?si=Lu9EO4b1SPcfXiQU And Apple just recently merged a authorship setup into USD https://github.com/PixarAnimationStudios/OpenUSD/pull/4188 (I didn’t realize it was merged till looking it up for thi

s response) But crucially , none of the global regulations require C2PA specifically. And with all synthetic data , you’re really relying on honor system for transparency. It’s not like the sensor to display pipeline that C2PA and Apple’s Reference Image can provide when enforced in hardware.

If you don't have an iphone, you can view he model by downloading them in the "options" drop-down menu to obtain the usdz file, which you can then use either with Pixar open-source suite https://github.com/PixarAnimationStudios/USD or other software that support the format. Or you can use an online file converter like https://products.aspose.app/3d/en/conversion/usd-to-obj and see the result in Meshlab. Direct in-browser visualization is possible but https://products.aspose.app/3d/fr/viewer worked but the scale was wrong and prevented to zoom enough. You can also view some high quality scan in the Apple's demo https://developer.apple.com/augmented-reality/quick-look/ (Edit: The ones with the "Made with object Capture" label which this service is a front-end for https://developer.apple.com/augmented-reality/object-capture... ).
