Meshroom

Meshroom is an open-source, node-based visual programming framework for creating, managing and running complex data-processing pipelines. Each node is one operation, and the output attributes of a node feed the next steps; when an attribute changes, only the affected downstream nodes are invalidated and cached intermediate results are kept. Pipelines can run locally or be distributed across a render farm, and interactive widgets visualise images and 3D data.

The README explains the core concepts: a graph of connected nodes, attributes that control each node, templates that bundle ready-to-use pipelines from plugins, and local or render-farm execution with progress, logs and resource tracking. Official releases ship with built-in plugins for computer vision and machine learning, led by the AliceVision plugin, which covers 3D reconstruction from multi-view images, camera tracking, HDR fusion, panorama stitching and photometric stereo, plus plugins for segmentation from natural-language prompts, depth estimation, RoMa matching, Gaussian splatting, research, MicMac and geolocation. Pre-compiled binaries are available, or you can build from source.
