Hi Camilo,  
as far as I know, there is not yet a smooth pipeline, just bit and pieces  
The first step is to reconstruct the plant from the point cloud. I am using this: [User guide — PlantScan3D 1.5 documentation](https://plantscan3d.readthedocs.io/en/latest/manual.html)  
From plantscan3d you get an MTG file that you have to modify further

here you can see what I am doing, but it requires a bit of manual work

> Hi, I am using [plantscan3D](https://github.com/fredboudon/plantscan3d) to reconstruct the topology of a leafless plant from a 3d point cloud. Plantscan3D gives me the following mtg as output, that is a list of nodes, instead of internodes. Do you know if Openalea.mtg can convert this list of nodes in a list of internodes (with their length, inclination, and diameters)? CODE : FORM-A CLASSES : SYMBOL SCALE DECOMPOSITION INDEXATION DEFINITION $ 0 FREE FREE IMPLICIT P 1 FREE FREE EXPLICIT N 2 FREE FREE EXPLICIT DESCRIPTION : LEFT RIGHT…

Maybe in Openalea is easier? Let’s wait for the opinion of the Openalea experts
