Hi everyone, I'm working with Core ML for object tracking and have successfully trained a couple of models. However, when I try to use the reference object file in the object tracking sample code from the WWDC video, it doesn't work. I'm training the model on a single-color plastic spherical object. Could this be the reason for the issue? I also attempted to use USDZ 3D assets that resemble the real object. Do these need to be trained with the Object Capture app to work properly? Speaking of the Object Capture app, my experience hasn't been great. When I scanned my spherical object, the result was far from a sphere—it looked more like a mushy dough. Any insights or suggestions would be greatly appreciated!

Hi, Object Capture's original sample code was released last year, and this year there was a talk about adding area mode to it. The talk links to the old Object Capture code - when can I expect to have the new one with area mode, and is there anything I can help you with to have it published faster? Thanks!

I would like to enable users of my iOS app to place an object they want to scan, for example, on a turntable, instead of walking around it, in order to generate a 3D model of it afterward. How can I achieve this with the Object Capture API?

Hy my name is zubair and i a blogger. I have recently create a website on gold price in oman url omangoldprices.com I maked a well design header footer and every thing as compared with my competitors but the header of my website disabled and not working on Macbook and macbook pro and the logo does not showing on IOS version Iphone 6 12.6.1. I am very comfused about that can anyone help me in?

Im trying to take an object capture, and scale it. What I did so far is create a Reality Composer project, insert the .objcap file into the project, and then scaled it from 100%, to 200%. I then extracted it as a USDZ. it just won't show up in the Xcode preview now, and im not sure why it doesn't show. Is there any way to fix this? im going crazy trying to find a fix for this to work.

Hi ,

Hi everyone, is it possible to use a 3D USDZ file to train a model in Create ML, I see there is an image option but it would be good to use these files from Reality Composer from object capture? Or is this in the works for forthcoming Xcode updates? Many Thanks Stuart

Hello, I'm currently building an app that implements the on-device object capture API to create 3D models. I have two concerns that I cannot find addressed anywhere on the internet: Can on-device object capture be performed by devices without LiDAR? I understand that depth data is necessary for making scale-accurate models - if there is an option to disable it, where would one specify that in code? Can models be exported to .obj instead of .usdz? From WWDC2021 at 3:00 it is mentioned that it is possible with the Apple Silicon API but what about with on-device scanning? I would be very grateful if anyone is knowledgeable enough to provide some insight. Thank you so much!

Hi all, I took bunch of photos using Apple's 'Capture Sample' iOS app. Even though the all images in .HEIC/HEIF file format that CLI tool logs the bunch of the following errors and couldn't find any solution. 1-) HEIF file is expected. 2-) *** Assertion failure in OCReturn OCNonModularSPI_CMPhoto_readResolution(const OCHeicReadHandle, const NSURL *__strong, uint64_t *, uint64_t *)(), CMPhoto+NonModularSPI.m:1271

I'm really excited about the Object Capture APIs being moved to iOS, and the complex UI shown in the WWDC session. I have a few unanswered questions: Where is the sample code available from? Are the new Object Capture APIs on iOS limited to certain devices? Can we capture images from the front facing cameras?
