Algorithm/code behind alignment tool

[VictorGimenez]

Hi,

I am giving a try in the align tool gluing the main mesh where I want to take as default and the rest of them I am selecting points manually (for example in person: nose, mouth, belly button in each .ply...) with point based glueing and it's working until the moment for my purpose, but I am doing it manually and I wish to automate this alignment as soon as in each .ply was found similar points and regions between each .ply, I would like to know how could I find these similar points/regions like using this align tool for example, I glue the firsh mesh and glue the next mesh finding points (like manually) but finding similar regions through code between two point clouds to reconstruct the entire object, any tip, algorithm?

Lot of algorithm for doing automatic matching. None of them have yet been implemented robustly inside MeshLab. Sorry.

I discovered by myself two days before yesterday the ICP (Iterative Closest Point) after making some research by specific keywords (computer graphics unfortunately isn't my research area but I am working in a project involving few applications about computer graphics) according my needs and it attended me, I was researching about a similar algorithm and it's aligning not matching. No problem that it wasn't implemented inside MeshLab I got it well, But thanks so much for trying to help!
