Meshroom
Node-based visual programming toolbox for creating, managing, and executing your data processing pipelines.
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.

mrHelloWorld: A hands-on tutorial series for building Meshroom plugins
mrHelloWorld is a pedagogical repository containing seven progressive, functional Meshroom nodes across six tutorials. Each node introduces new concepts — starting with a simple image copy and ending with a pretrained deep learning model for semantic segmentation. The goal is to give developers a clear, working reference instead of having to reverse-engineer production plugins. This… »

Baptiste Brument Thesis Defense
We are pleased to announce the PhD defense of a thesis dedicated to improving the robustness and accuracy of 3D reconstruction methods by integrating explicit models and leveraging physical (reflectance, shading, refraction) and geometric (gradients, silhouettes) properties. Rather than proposing entirely new approaches, this research enhances existing geometric and differentiable rendering frameworks, extending their applicability… »
