[공부기록]100일_59일차

어제 ARKit을 맛보면서 든 생각

 

- configureation이 무엇일까?

- AR 컨텐츠를 사용하기 위해서는 convert과정 또는 apple이 제공하는것을 써야겠구나

- usdz도구?

 

 

ARConfiguration

An object that defines the features enabled in your AR session

 

: AR 세션에서 활성화된 기능을 정의하는 오브젝트

 

USDZ도구로 ar컨텐츠를 변환한다

잘 모르겠다,,,,,,,

 

 

음,,,,,,,뭐를 어떻게 공부해야하지요
