问题 I'm trying to place a large 3D object (generated from .obj file) in front of camera and not able to do it. The model gets placed considering the hit result as the center point.

ARCore Compatible devices

阅读更多关于 ARCore Compatible devices

问题 What are the next Android smartphones to be compatible with ARCore? Is there a known list of future compatible devices yet? Maybe a general project schedule? We are about to purchase some units for AR development assessments, at first we thought about trying one of the Tango devices out there (we already had a good experience with Tango), but our current bet is that the ARCore platform will beat it in terms of market share.

问题 Good day everyone, I am currently on the process of creating my first AR application using unity and vuforia sdk.

My question is while the phone scans for image target there should be a message saying "Scanning for image target"

阅读更多关于 ARCore + Unity + Augmented Images - Load different prefabs for different Images

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
