📣 News

[2026-07] 🎉 InfiniSplat has been conditionally accepted to SIGGRAPH Asia 2026 (Journal Track)!

[2026-07] 🎉 Inference code for RGB-only and depth-sensor-guided 3D Gaussian reconstruction is available now!

🧩 What can InfiniSplat do?

InfiniSplat supports two practical modes for single-image 3D Gaussian reconstruction:

Capability	Input	Output
Monocular 3D Gaussian Reconstruction	RGB Image	3DGS
Depth-Sensor-Guided 3D Gaussian Reconstruction	RGB Image + Depth	3DGS

⚙️ Installation

Please see INSTALL.md for environment setup and checkpoint download.

🚀 Inference

RGB Only

Run a single image:

python -m src.demo.infer_batch_images --input examples/data/rgb_demo/pexels-masi.jpg

Run a directory using the bundled examples:

python -m src.demo.infer_batch_images --input examples/data/rgb_demo

Depth-Sensor-Guided Reconstruction

Run a single RGB and depth pair with matching filename stems in the same directory:

python -m src.demo.infer_batch_images \
  --mode lidar \
  --input examples/data/lidar_demo/eth3d_kicker.png

Run the bundled RGB and depth pairs:

python -m src.demo.infer_batch_images \
  --mode lidar \
  --input examples/data/lidar_demo

See docs/inference.md for camera parameters, output control, and other optional arguments.

🖥️ Web Demo

The local Gradio demo provides RGB reconstruction, staged PLY and standalone HTML downloads, and an interactive Gaussian viewer. After preparing the inference environment, launch it with:

python demo.py

Open http://127.0.0.1:7860 in a browser. The demo reuses checkpoints/infinisplat_rgb.ckpt when available and otherwise downloads the released RGB checkpoint from PLUS-WAVE/InfiniSplat. Set INFINISPLAT_CHECKPOINT to use a checkpoint at another path.

The hosted version is available on the Hugging Face Space.

🙏 Acknowledgments

We sincerely thank the authors of DINOv3, Depth Pro, InfiniDepth, and gsplat for their excellent work. InfiniSplat is built on top of these projects.
