PartVerse-XL (FullPart) — 3D Parts Dataset

A large-scale 3D parts dataset. It contains textured part meshes, whole-object meshes, annotations, captions. Related dataset: PartVerse.

Contents

• Split archives (parts):
  • textured_part_glbs.tar.gz00 … textured_part_glbs.tar.gz66 (67 parts)
  • normalized_glbs.tar.gz00 … normalized_glbs.tar.gz08 (9 parts)
• Other files:
  • anno_infos.tar.gz
  • text_captions.json
  • train.csv
  • val.csv
  • metadata.csv

What’s inside (after extraction)

• textured_part_glbs/: GLB meshes for each decomposed part with textures.
• normalized_glbs/: GLB meshes for full, normalized objects.
• anno_infos/: auxiliary files for part statistics and processing.
• text_captions.json: auto-generated captions for parts (from a VLM).
• train.csv / val.csv: instance lists for train/eval.
• metadata.csv: metadata aligned with Objaverse-XL.

Expected directory layout:

├── textured_part_glbs/
├── normalized_glbs/
├── anno_infos/
├── text_captions.json
├── train.csv
├── val.csv
└── metadata.csv

Download

Using huggingface_hub:

from huggingface_hub import snapshot_download

local_dir = "dataset"
snapshot_download(
    repo_id="dscdyc/partversexl",
    repo_type="dataset",
    local_dir=local_dir,
    local_dir_use_symlinks=False
)

Join split archives and extract

cd dataset
cat ${TARGET_PACKAGE}.tar.gz* | tar xzf - -C /path/to/target/

Intended uses

• Part-level generation, assembly, retrieval, and analysis
• Whole-object understanding and alignment with parts
• Text–shape alignment and retrieval
