Using a Substance Painter IRay render image (the robot) and an Arnold render image (old woman) that I made in my last 2 semesters of university, I compiled the image files as a .MIND file.
As a .MIND file, these images can be used as targets for a webAR application!
By utilizing the MindAR.JS library and AFrame.IO library in a HTML page, I created a MindAR application and deployed it to GitHub pages:
Go here on your phone and point your phone camera at the images of the robot and the lady.
