Mapping UID to original Objaverse objects

[0010SS]

Hi! Thanks for your wonderful work. I'm wondering whether there are ways in which we can map the UID of an object back to its original record in the Objaverse annotations so that we can directly download the mesh object from Objaverse. Thanks!

Hello -- if I recall, our UID is the same as Objaverse's UID category. So you should be able to access the Objaverse objects using our UID and their API

Hi @0010SS , thanks for your interests~

As Chris said, all of our uid for Captions and PointClouds (can be downloaded at https://huggingface.co/datasets/tiange/Cap3D) are named with the uid provided by Objaverse.

I provide one example here for your reference:

# load our captions
import pandas as pd
captions = pd.read_csv('Cap3D_automated_Objaverse_no3Dword.csv', header=None)

## captions:
##                                        0                                                  1

# download via Objaverse API
import objaverse
import multiprocessing
processes = multiprocessing.cpu_count()

uids_download = captions[0][:100].values
objects = objaverse.load_objects(
     uids=uids_download,
     download_processes=processes
 )
