Meshroom is an open-source, node-based visual programming framework—a flexible toolbox for creating, managing, and executing complex data processing pipelines.

Meshroom uses a nodal system where each node represents a specific operation, and output attributes can seamlessly feed into subsequent steps. When a node’s attribute is modified, only the affected downstream nodes are invalidated, while cached intermediate results are reused to minimize unnecessary computation.

Meshroom supports both local and distributed execution, enabling efficient parallel processing on render farms. It also includes interactive widgets for visualizing images and 3D data. Official releases come with built-in plugins for computer vision and machine learning tasks.
