arcore

问题 I am a beginner in the field of augmented reality, working on applications that create plans of buildings (floor plan, room plan, etc with accurate measurements ) using a smartphone. So I am researching about the best AR SDK which can be used for this. There are not many articles pitting Vuforia against ARCore and ARKit. Please suggest the best SDK to use, pros and cons of each. 回答1: Updated: October 30, 2019 . TL;DR Google ARCore allows you build apps for Android and iOS, with Apple ARKit

问题 How do I assign different prefabs to different images? right now, I have all my prefabs loading in on top of each other but how do I get it so each prefab loads in only once on top of one image so each image has a different prefab? I've modified the sample code (the frame corners) to load in my own prefab and used a dictionary to pair the prefabs with images from the database but when the program runs it instatiates all the prefabs in the same place rather than putting one prefrab on each

问题 Is it possible to have Cloud Anchors be accessed after 24 hours and/or the feature points re-activated? 回答1: Cloud Anchors stored at Google ARCore Cloud Anchor Service expire after 24 hours .
