Overview
Objaverse++ extends Objaverse by adding neural field representations (NeRF, 3D Gaussian Splatting) and richer annotations for simulation and high‑fidelity rendering. Official sources:
Neural Representations
- NeRF: learns a continuous radiance field; excellent detail, higher training cost
- 3DGS: many Gaussian splats; very fast rendering, great for interactive scenes
Background reading: NeRF (Mildenhall et al.) • 3DGS
System Requirements
- GPU: 24GB VRAM recommended for larger scenes (e.g., RTX 4090/A6000)
- RAM: 64–128GB for parallel preprocessing
- Storage: fast NVMe for neural caches; offload archives to NAS
- Software: PyTorch + CUDA; pin versions per project for reproducibility
Python Workflow
pip install objaverse-plus torch torchvision
import objaverse_plus as oplus
uids = ["n1b2c3","n4d5e6"]
neural_objs = oplus.load_with_neural(uids=uids, download_dir="./neural_data")
# Example: build a simple dataset wrapper
dataset = oplus.NeuralDataset(neural_objs)
Ensure CUDA versions match your PyTorch build. Use mixed precision where it helps.
Performance Tips
- Profile Gaussian counts and prune for target FPS
- Use caching to avoid redundant conversions
- Benchmark view sampling with a fixed camera path

FAQ
Is every object in ++ a neural field?
No; ++ adds many neural fields but not all objects have NeRF/3DGS versions.
Which is faster for real‑time?
3D Gaussian Splatting typically renders much faster than NeRF with competitive quality.
