06 – 3D model yourself

So…
You don’t know how to do 3D modelling but you know a little bit about programming and want to do cool stuff ?

Then read this post because today we will learn how to make a 3D model of a person in just 2sec … from a photo !

Yes It works ! Check this out :

The algorithm that does this is simple :
Give it a photo, and it will create a 3D model of the person in the photo.

Did I tried it my self ? Of course I did :

• 

• 

• 

Because I got a 3D printer, I could print the generated 3D models
Think of the opportunities ! This could make great gifts, you could also make a candle with your shape, or import yourself in a video game !
The technology was used by the Corridor crew in one of their video:

Ok, but how does it work ?

All the magic was made in the Facebook Reality Labs _{(or the Meta Reality Labs idk)} And lucky for us, they have described all of their work in a paper :

_{Read it ! That’s an order}

Their method consist of using a neural network architecture with several steps that can be independently trained, they state that :

“This approach significantly outperforms existing state-of-the-art techniques”

Doesn’t it sound great ?

They used for training hundreds of synthetically generated high quality scanned 3D human mesh models, you can by them here :

Finally, if you want to try the algorithm yourself and maybe print a tiny you, you can find more information on their GitHub page :

I hope you have fun trying it, I know I did
