If you are using a supported browser, then you will see this button around the bottom right of the 3D model
Supported browsers include Safari for iPhone users and AT LEAST Chrome or Brave for Android users (maybe others).
I'm an iPhone user and haven't been able to confirm another browser that this works with. I did try it on my Android tablet and it worked with Chrome and Brave for the ones I tried
When you click that button from the previous step, you'll be greeted with an option to "View in AR" 👉 CLICK IT
Then just move around your phone camera slightly on a surface you want to have the model show up on and 💥BAM💥 IT'S ALIVE!
Now, you can click and drag it to another spot on the table, or to another surface entirely
You can also use 2 fingers and zoom in, or rotate
From the pic on the right you can also see there is an option to snap a pic where it is in space
The last option is at the top you'll see "AR" or "Object"
We have been on AR view, but you can press Object view to see the model in it's own space with a blacked out background
Then when you're finished, just click the "x" at the top left to return back to the website
Thanks for playing!
