What is it?

Meshroom is a node-based visual framework for building and running data processing pipelines. Each node performs one operation, and its output attributes can feed into later steps. When a parameter changes, only the affected downstream nodes are recomputed, while cached intermediate results are reused.

The bundled AliceVision plugin provides pipelines for 3D reconstruction from multi-view photos, camera tracking, HDR fusion from bracketed exposures, panorama stitching including fisheye and motorized heads, and photometric stereo. Additional plugins from MeshroomHub add segmentation, monocular depth estimation, dense feature matching, Gaussian splatting and geolocation.

Execution can run locally or be distributed to render farms. The interface includes a graph editor, per-node logs and statistics, and 2D and 3D viewers for inspecting outputs.

Key features

  • 01Node graph where changing one attribute recomputes only downstream nodes.
  • 02Photogrammetry pipeline turning multi-view photos into 3D models and camera poses.
  • 03HDR fusion and panorama stitching pipelines from AliceVision.
  • 04Local or render-farm distributed execution.
  • 05Built-in 2D and 3D viewers and per-node logs.

Use cases

  • Creating 3D models of objects or buildings from a set of photographs.
  • Estimating camera motion from video or image sequences.
  • Merging bracketed exposures into HDR images or stitching panoramas.
  • Running large batches of reconstruction jobs across a render farm.

Quick start
