Viewing rich USDZ files with ARKit consumes a lot of memory.
Even in 3D with a file size of several tens of MB, the memory consumption due to rendering will be several hundred MB, and if you try to display multiple files, it will drop.

I usually use SceneKit, but…

After read this, you will have already known how to use TensorFlow Object Detection API.


The sample notebook

You can try the inference of TensorFlow Object Detection API by just running the cells in the sample notebook one by one. …
