Is it possible to use deep learning with 3d point cloud?

I am working with a point cloud.

I would like to develop a deep learning method which is able to recognize specific 3d geometry in a point cloud.

Is it possible to work directly with deep learning and point cloud or i need to make 2d projection of my 3d object ?

Yes, you can use PointNet to recognize the point cloud data. You do not need the 2d projection and directly feed point clouds into the PointNet.

This is a demo for PointNet classification. I hope it helps you.
