DynamicObjaverseProcessed

67,084 animated (4D) 3D meshes curated from Objaverse-XL, quality-ranked by ICP-based non-rigid deformation intensity.

Overview

Starting from 71,104 curated UIDs, the processing pipeline downloads, unifies formats to .glb, and classifies meshes by animation quality:

71,104 curated UIDs → 67,746 downloads → 67,639 unified .glb → 67,084 true 4D meshes

All meshes are in binary glTF (.glb) format with embedded animations.

Quintile Ranking

Meshes are ranked by ICP residual — a measure of non-rigid deformation after factoring out rigid-body motion (translation/rotation). Higher ICP = more interesting mesh deformation (e.g., character animation, cloth simulation).

Quintile	Files	ICP Range	Size	Description
Q1 (top)	13,417	0.039 – 0.996	32 GB	Strongest deformation
Q2 (high)	13,417	0.027 – 0.039	44 GB
Q3 (mid)	13,417	0.017 – 0.027	51 GB
Q4 (low)	13,417	0.003 – 0.017	38 GB
Q5 (bottom)	13,416	0.000 – 0.003	25 GB	Subtle / rigid-body motion

Usage

# Download and extract a specific quintile
from huggingface_hub import hf_hub_download
import tarfile

path = hf_hub_download("littlekoyo/DynamicObjaverseProcessed", "quintile_1_top.tar", repo_type="dataset")
with tarfile.open(path) as tar:
    tar.extractall("./meshes")

# Load the classification manifest
import json
path = hf_hub_download("littlekoyo/DynamicObjaverseProcessed", "classification.jsonl", repo_type="dataset")
records = [json.loads(line) for line in open(path)]

classification.jsonl fields

Field	Description
uid	UUID identifier (also the filename without .glb)
classification	true_4d / static / error
icp_residual_normalized	Non-rigid deformation intensity (normalized by bbox diagonal)
max_displacement_normalized	Raw vertex displacement (including rigid motion)
overall_amplitude	Keyframe amplitude metric (supplementary)
quintile	1–5 (1 = most deformation, 5 = least; 0 for non-4D)
icp_rank	Rank within true_4d (1 = highest ICP)
source_path	Original file path in the processing pipeline
