DX.GL Multi-View Datasets for NeRF & 3D Gaussian Splatting

Multi-view training datasets rendered from CC0 3D models via DX.GL. Each dataset includes calibrated camera poses, depth maps, normal maps, binary masks, and point clouds — ready for nerfstudio out of the box.

10 objects × 196 views × 1024×1024 resolution × full sphere coverage.

Quick Start

# Download a dataset (Apple, 196 views, 1024x1024)
wget https://dx.gl/api/v/EJbs8npt2RVM/vCHDLxjWG65d/dataset -O apple.zip
unzip apple.zip -d apple

# Train with nerfstudio
pip install nerfstudio
ns-train splatfacto --data ./apple \
  --max-num-iterations 20000 \
  --pipeline.model.sh-degree 3 \
  --pipeline.model.background-color white

Or use the download script:

pip install requests
python download_all.py

Specs

Property	Value
Views	196 per object
Resolution	1024×1024
Coverage	Full sphere (±89° elevation)
Point cloud	~200k points
Camera distribution	Fibonacci golden-angle spiral
Background	Transparent (RGBA)
Lighting	Studio HDRI + directional lights

Camera Distribution

Views are distributed on a full sphere (±89° elevation) using a golden-angle Fibonacci spiral. The distribution is uniform in solid angle — more views near the equator, fewer near the poles — optimized for NeRF/3DGS training.

Pre-trained 3DGS Splats

We include pre-trained Gaussian Splat .ply files (nerfstudio splatfacto, 20k iterations, SH degree 3) for each object. Download them with:

python download_all.py --splats

Or view them directly:

• DX.GL Splat Viewer (all 10 models, use ← → to browse)
• SuperSplat Editor (drag-drop the .ply)
• nerfstudio viewer: ns-viewer --load-config outputs/*/config.yml

Training Parameters

ns-train splatfacto --data ./dataset \
  --max-num-iterations 20000 \
  --pipeline.model.sh-degree 3 \
  --pipeline.model.background-color white \
  --pipeline.model.cull-alpha-thresh 0.2 \
  --pipeline.model.densify-size-thresh 0.005 \
  --pipeline.model.use-scale-regularization True \
  --pipeline.model.max-gauss-ratio 5.0

Training time: ~10 minutes on RTX 4000 Pro Ada (70W) at the 196×1024 tier.

Rendering Pipeline

Datasets are rendered using DX.GL's cloud GPU rendering pipeline:

• Lighting: Studio HDRI environment with PBR materials
• Camera: Fibonacci golden-angle sphere distribution
• Depth: Tight near/far planes from model bounding sphere for maximum precision
• Point cloud: Back-projected from depth maps, ~1000 points per view
• Background: Transparent (RGBA)

Modalities

Modality	Format	Notes
RGB	PNG, RGBA	Transparent background, PBR-lit
Depth (8-bit)	PNG, grayscale	Normalized to near/far range
Depth (16-bit)	PNG, grayscale	RG-encoded, higher precision
Normals	PNG, RGB	World-space, MeshNormalMaterial
Masks	PNG, grayscale	Binary alpha from RGB alpha channel
Point Cloud	PLY, binary	XYZ + RGB, ~100k points
Camera Poses	JSON	4×4 camera-to-world matrices

Feedback

We're actively improving the rendering pipeline. If you find issues with depth accuracy, mask quality, camera calibration, or view distribution — please open a Discussion on this repo. Specific feedback we're looking for:

• Depth map accuracy at object edges
• Mask quality for transparent/reflective materials
• Point cloud alignment with RGB views
• View distribution quality for your training method
• Missing modalities or metadata
• Any other issues or suggestions?
