Meshroom (3D Photogrammetry)by alicevision
3D Reconstruction Software based on AliceVision framework. Turn photos of real objects into textured 3D meshes. It's also a popular Free Alternative to RealityCapture for creators who don't want to pay a monthly subscription.
What Is Meshroom (3D Photogrammetry)?
New to GitHub repos? Here's what this actually does, in plain language:
An industry-standard 3D reconstruction and photogrammetry application that transforms routine smartphone photo arrays into textured 3D geometric meshes.
Strengths, Limitations & Is It Safe to Install?
An honest breakdown before you install anything on your PC:
โ What It Does Well
- A genuinely capable free alternative to expensive photogrammetry software like RealityCapture
- Comes with a real GUI and a visual node pipeline, not just command-line scripts
- Exports textured models directly usable in Blender and game engines
โ What It Can't Do / Limitations
- Very compute/GPU-intensive processing โ reconstructions can take a long time
- Needs many good-quality, well-overlapping source photos for decent results
- Steep learning curve to get clean results โ bad photo sets produce broken/holey meshes
๐ก๏ธ Is It Safe to Install?
Safe, official AliceVision/Mikros Image research project. Requires an Nvidia CUDA-compatible GPU to run at all.

How to Use Meshroom (3D Photogrammetry) (Beginner Quick Start Tutorial)
First time launching this application? Follow our beginner operational workflow:
Take Overlapping Photos
Photograph your subject from many angles with 60-80% overlap between shots.
Import Photos into Meshroom
Drag all your photos into the Meshroom window to start a new project.
Run the Pipeline
Click Start โ Meshroom automatically runs camera alignment, depth mapping, and mesh reconstruction.
Export the 3D Model
Once processing completes, export the textured mesh (OBJ/FBX) for use in Blender or a game engine.
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.
