I want to create an application like this app https://youtu.be/5PIZ_qo9rUg .After searching I found this article
but I could not do two things.
The first I could not run on the mobile and give me a problem using the camera
The second is that I can not create a custom marker instead of the default marker https://stemkoski.github.io/AR-Examples/markers/hiro.png
Thanks in advance
