[![CII Best Practices](https://bestpractices.coreinfrastructure.org/projects/2997/badge)](https://bestpractices.coreinfrastructure.org/projects/2997)



Meshroom is a free, open-source 3D Reconstruction Software based on the [AliceVision](https://github.com/alicevision/AliceVision) Photogrammetric Computer Vision framework.



Learn more details about the pipeline on [AliceVision website](http://alicevision.github.io).



See [results of the pipeline on sketchfab](http://sketchfab.com/AliceVision).



Continuous integration:

## Photogrammetry



Photogrammetry is the science of making measurements from photographs.

It infers the geometry of a scene from a set of unordered photographs or videos.

Photography is the projection of a 3D scene onto a 2D plane, losing depth information.

The goal of photogrammetry is to reverse this process.



See the [presentation of the pipeline steps](http://alicevision.github.io/#photogrammetry).

## Customization



### Custom Pipelines



You can create custom pipelines in the user interface and save it as template: `File > Advanced > Save As Template`.

You can define the `MESHROOM_PIPELINE_TEMPLATES_PATH` environment variable to specific folders to make these pipelines available in Meshroom.

In a standard precompiled version of Meshroom, you can also directly add custom pipelines in `lib/meshroom/pipelines`.



### Custom Nodes



You can create custom nodes in python and make them available in Meshroom using the `MESHROOM_NODES_PATH` environment variable.

[Here is an example](meshroom/nodes/blender/ScenePreview.py) to launch a Blender rendering from Meshroom.

In a standard precompiled version of Meshroom, you can also directly add custom nodes in `lib/meshroom/nodes`.

To be recognized by Meshroom, a custom folder with nodes should be a Python module (an `__init__.py` file is needed).



## License



The project is released under MPLv2, see [**COPYING.md**](COPYING.md).

## Get the project



You can [download pre-compiled binaries for the latest release](https://github.com/alicevision/meshroom/releases).  



If you want to build it yourself, see [**INSTALL.md**](INSTALL.md) to setup the project and pre-requisites.



Get the source code and install runtime requirements:

```bash

git clone --recursive git://github.com/alicevision/meshroom

cd meshroom

pip install -r requirements.txt

```



## Start Meshroom



You need to have [AliceVision](https://github.com/alicevision/AliceVision) installation in your PATH (and LD_LIBRARY_PATH on Linux/macOS).



 - __Launch the User Interface__



```bash

# Windows

set PYTHONPATH=%CD% && python meshroom/ui

# Linux/macOS

PYTHONPATH=$PWD python meshroom/ui

```



On Ubuntu, you may have conflicts between native drivers and mesa drivers. In that case, you need to force usage of native drivers by adding them to the LD_LIBRARY_PATH:

`LD_LIBRARY_PATH=/usr/lib/nvidia-340 PYTHONPATH=$PWD python meshroom/ui`

You may need to adjust the folder `/usr/lib/nvidia-340` with the correct driver version.



 - __Launch a 3D reconstruction in command line__



```bash

# Windows: set PYTHONPATH=%CD% &&

# Linux/macOS: PYTHONPATH=$PWD

python bin/meshroom_batch --input INPUT_IMAGES_FOLDER --output OUTPUT_FOLDER

```



## Start Meshroom without building AliceVision



To use Meshroom (ui) without building AliceVision

*   Download a [release](https://github.com/alicevision/meshroom/releases)

*   Checkout corresponding Meshroom (ui) version/tag to avoid versions incompatibilities

*   `LD_LIBRARY_PATH=~/foo/Meshroom-2023.2.0/aliceVision/lib/ PATH=$PATH:~/foo/Meshroom-2023.2.0/aliceVision/bin/ PYTHONPATH=$PWD python3 meshroom/ui`



## Start and Debug Meshroom in an IDE



PyCharm Community is free IDE which can be used. To start and debug a project with that IDE,

right-click on `Meshroom/ui/__main__.py` > `Debug`, then `Edit Configuration`, in `Environment variables` : 

*   If you want to use aliceVision built by yourself add: `PATH=$PATH:/foo/build/Linux-x86_64/`

*   If you want to use aliceVision release add: `LD_LIBRARY_PATH=/foo/Meshroom-2023.2.0/aliceVision/lib/;PATH=$PATH:/foo/Meshroom-2023.2.0/aliceVision/bin/` (Make sure that you are on the branch matching the right version)
