How do I render point clouds?

I received some emails/messages asking me how did I render point clouds in P2P-NET and LOGAN.

Here is how:

• Convert the point cloud into a set of spheres, and save it in an obj file. You can use the matlab code under "pc2sphere".

• Use Keyshot to render the obj file. The software provides a library of nice materials. The education version is $95/yr.

• You can also write a python script to render a batch of files. See the document here.

Hope this is helpful.
