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