Mesh - getParticles()

[HarshithaBR]

Dear Organizers,

I am trying to get a mesh for the cloth in the dressing task, and have been following example_cloth_attach.py.

I have modified test_dressing.py and I am trying to check the data and get the particles from the mesh.
Q1) What is the best way to get the path for the cloth mesh.

     t_shirt_path = os.path.join(mesh_path, 'Tshirt.obj')
     mesh = env.LoadCloth(path=t_shirt_path)

Q2) If I print mesh and mesh.data, I am getting the below. Can you please suggest on how to work with the same?

type(mesh):  <class 'pyrcareworld.attributes.cloth_attr.ClothAttr'>`

mesh.data: {}

hence, position1 = mesh.data['particles'][500] would throw an error.

Thanks and best Regards
Harshitha B R

Hi @HarshithaBR does this example work for you? https://github.com/empriselab/RCareWorld/blob/phy-robo-care/pyrcareworld/pyrcareworld/demo/examples/example_cloth_attach.py

Which commit is it at before you did the pull? I highly doubt some local changes might have affected this since we haven't updated the example player for a while.

Hi

I was at commit : 30d03bf
before i did the git pull

Except for doing the pull, did you install anything else? The newest commit works on my side. You can try rebooting your system and see if it works. If it still doesn't work, you can try installing the environment from scratch. Especially, see if these commands will help:

sudo apt-get update
sudo apt-get install libassimp-dev libopenblas-dev liblapack-dev

It looks like the libraries are not working.

okay, i will try it out

Thank you!

Hello!

I also ran into the same issue. The 'example_cloth_attach.py' works for me but once I run 'cloth.getParticles()', it returns None in the 'test_dressing.py --graphics'. Would you be able to check this? I installed today with the latest update on Ubuntu 20.04
