This will sometimes result in a background that looks a little blurry, so it"s best khổng lồ avoid intricately patterned backdrops.

To create such a photo, choose 3d Photo when post to Facebook, and use new portrait mode on i

But how does it work under the hood? I lượt thích to learn new ideas by reading other people’s code. So I was curious enough to lớn learn how they implemented this effect at Facebook. Here is the story. If you just want to know the tech, skip to lớn the “how it all works” part.
First guess, fragment shader?There is a popular way of faking 3 chiều with shader, by using depth map and distort image pixels with fragment shader in Web
GL:
Check it out live here. Everything is flat here, it’s just 3 chiều illusion.At first I thought facebook team went for that, as it’s very easy lớn do, and the image kích cỡ is quite small. But that’s not how they made it.
