Trying to export lpy model into MTG or XYZ coordinates

Software Openalea
1

Hello,
I would like to export my Lpy model into some format in which my arhitecture can be understood by other people not familiar with LPy I don’t know if the best format is MTG or if there is a way to extract the spatial coordinates of my architecture.
I was aproaching the problem using the YOUTUBE lessons from prof @godin ( MC 15 LPy Application Programming Interface and LPy Tools library) and I discovered the LPy tools ( Point_sampler documentation — lpy_tools 0.1.0 documentation (inria.fr).

However I really can’t manage to install lpy_tools
I tired with:
1)

conda install lpy_tools -c mosaic -c fredboudon -c conda-forge

as suggested here: MOSAIC / lpy_tools · GitLab (inria.fr)

conda install -c mosaic lpy_tools

as suggested here: Lpy Tools :: Anaconda.org

I don’t know what I can do.
can somebody help me?

Thanks so much
Francesca

Hi Francesca,
Nice to read you.
With Fred(@fredboudon ), we have developed a full mapping between lpy and MTG in both directions (LPy to MTG and MTG 2 LPy). You can read the doc here : 9. Lsystem and MTGs — openalea.mtg 2.1.2 documentation
And there are several examples in the test repository (github.com/openalea/mtg/test)

from openalea.lpy import *
from openalea.mtg.io import lpy2mtg, mtg2lpy, axialtree2mtg, mtg2axialtree

exported_symbols = ['A', 'B', 'C']

def export_to_mtg(lstring):
  parameters = {}
  scales = {}
  for m in exported_symbols:
    mod = ModuleClass.get(m)
    scales[m] = mod.scale
    parameters[m] = mod.parameterNames
  return axialtree2mtg(lstring,scales,None,parameters)

To install lpy and mtg from openalea

conda install openalea.lpy openalea.mtg -c openalea3 -c conda-forge

Hi Francesca,

You can export your l-scenes as standard obj file just by saving it using a .dot extension:

scene.save(f’out/my_plant.obj’)

Thanks so much @godin I succeded in export it as .obj.
However I did not succed in export the mtg file @pradal the “ModuleClass.get(m)” output “none” and the rest of the code is aborted

anyway I hope that .obj file it’s ok for my purposes. thanks so much everyone

cheers,

Good afternoon,

thanks so much

Dear Francesca,
I am not sure I understand well your question. Can you explain why do you need to import .obj files in L-py ?
Best,

Ch.
