3D Gaussian Splatting (Inria)by graphdeco-inria
Real-time radiance field rendering for 3D scene reconstruction from video/photos with 1080p 60fps rendering. It's also a popular Free Alternative to Luma AI & NeRF for creators who don't want to pay a monthly subscription.
What Is 3D Gaussian Splatting (Inria)?
New to GitHub repos? Here's what this actually does, in plain language:
A revolutionary real-time rendering framework capable of transforming simple location video sweeps into photorealistic, navigable 60fps 3D cinematic environments.
Strengths, Limitations & Is It Safe to Install?
An honest breakdown before you install anything on your PC:
โ What It Does Well
- The original research implementation behind one of the most exciting recent breakthroughs in 3D scene capture
- Produces impressively photorealistic, navigable 3D scenes from ordinary video
- Can train a usable scene in around 15 minutes on suitable hardware
โ What It Can't Do / Limitations
- This is research-grade code, not a polished consumer app โ expect rough edges
- Needs a strong Nvidia GPU with good VRAM (RTX 3080/4090-class recommended)
- Requires comfort with Python environments and CUDA setup โ not for casual beginners
๐ก๏ธ Is It Safe to Install?
Safe, official academic research repo from Inria. Flagged clearly: this is for advanced/technical users, not a beginner's first project.

How to Use 3D Gaussian Splatting (Inria) (Beginner Quick Start Tutorial)
First time launching this application? Follow our beginner operational workflow:
Capture a Video Sweep
Film a smooth video walking around your subject or scene, covering it from multiple angles.
Run Structure-from-Motion First
Process your video/photos through COLMAP to estimate camera positions โ this is a required prerequisite step.
Train the Gaussian Splat Model
Run the training script pointing at your COLMAP output โ this takes roughly 15-30 minutes on a good GPU.
python train.py -s <path-to-colmap-data>View Your 3D Scene
Use the included real-time viewer to fly around your reconstructed 3D scene.
Troubleshooting & Fix Common Errors
If you encounter unexpected errors or installation failures, apply these verified diagnostic fixes:
Root Cause: Your GPU VRAM is full because the AI model batch size or resolution is too high.
Root Cause: The required software is installed but not added to your Windows Environment System PATH.
Root Cause: Installed PyTorch binary does not match your Nvidia GPU CUDA driver version.
Root Cause: Another WebUI or Python background process is already running on the default local port.
