Object Capture API please

When I first got this app over a year ago it was fine compared to the competition and $5 for unlimited scans you can’t complain too much. Not that Apple Object Capture has come out it has rendered whatever algorithm Trnio uses completely useless. I have run the same photo set through Trnio, PhotoCatch on my Mac Mini M1, and an app I won’t name that uses Object Capture API. If Trnio even produces a result it’s not even close to being as good as Object Capture. Object capture will also use a turntable without any special background. Trnio is like most other photogrammetry programs and won’t do a turntable unless you give a solid black background with ring lights in a dark room. If Trnio could switch to the Object Capture API the app would be perfect

Developer Response ,

Thanks for the feedback. Trnio currently does not support your specific turntable use case. We will be updating the app algorithms shortly to support LiDar-photo fusion capture (not available in object capture) and turntable mode. Thanks!

Great program with even greater developers

While I have only reached the tip of the iceberg so to say in terms of making full use of this apps potential, having only done a few scans myself. The results from these scans speak for themselves and scans from the community further illustrate the capabilities offered. I’ve had a few small interactions with the developers via their Instagram and their interest in improving the app and taking feedback from users is very apparent. The only complaint which could be lodged against this program is long load times, which I don’t see as even a fair argument against the program seeing as it doesn’t have any kind of monthly subscription to pay for blazing fast servers, just a one time $5 entry price.
TLDR: App works great, Devs are great, worth every penny!

Wonderful reaults easy to use

Ive been enjoying this app - you can see my experiments on sketchfab under my account tmixer. I would like more detail in my models, allowance for manual photo capture and more photos as well as a manual crop mode. I hope AR mode keeps developing because its great for scenes. Good work devs and thank you for a one time purchase model. I tell everyone about this app in my creative circles. Cheers

Edit: thanks for the reply devs. I do realize you can import your own photos for processing but thank you for the tip. What I was referring to was the ability for manual control of the shutter as well as the auto shooting it does currently. Thanks for considering this. Maybe a pro option for would allow higher resolution models and more than 70 photos.

Best to you all

Developer Response ,

Thanks for the review! We're currently updating our queue to drastically reduce wait times, but we'll be adding editing shortly. You can actually import images. Click on the top left button to import any image from your camera roll. Glad you like the pricing. We're trying to keep it affordable.
