On Tuesday 09 December 2025 , Candice Bentéjac and Fabien Castan presented Meshroom at an open source after work event hosted by Cap Digital and co-organized by CST, and FICAM. The session concluded with engaging discussions among the attendees.

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 to challenging scenes and materials.
The work introduces four main contributions:
This thesis advances the pursuit of high-fidelity geometry reconstruction in complex and previously unresolved imaging scenarios.

Meshroom has now become a node-based visual programming toolbox for creating, managing, and executing complex data processing pipelines, with a new plugin architecture.
Standard computer vision pipelines such as photogrammetry, camera tracking, HDR panorama, Lidar Meshing, Raw image files conversion and color calibration are now unified within the AliceVision plugin, featuring numerous improvements and optimizations.
Additionally, new AI-powered capabilities include a semantic segmentation plugin and a collection of open-source extensions available via the new MeshroomHub: https://github.com/meshroomHub. This platform enables Gaussian Splatting, monocular depth estimation, and other exploratory features, welcoming developer contributions to expand and enhance these capabilities for upcoming releases.
AI segmentation nodes that identify and isolate image objects using natural language prompts, enabling intuitive content-aware processing through foundation models.
We’re excited to introduce new experimental Machine Learning plugins available on MeshroomHub.
These plugins showcase the future of Meshroom workflows, though they currently require developer setup and cannot be installed through the user interface yet.
Based on AliceVision 3.3.0.
The César & Techniques Innovation Award 2025 was awarded to MPC.
MPC is a company that offers comprehensive, tailor-made VFX solutions for feature films and series by finding technical and creative post-production solutions that enable them to bring their vision to life.
Presentation of the innovation
MPC has developed Meshroom an open source tool to automate camera tracking. This innovation accurately estimates camera movements during filming, saving valuable time when starting VFX work.
AliceVision Receives Support from CNRS’s OPEN Project.
We are proud to announce that AliceVision has received new funding from the OPEN project of the CNRS (French National Centre for Scientific Research) led by Jean-Denis Durou: “DOPAMIn : Diffusion Open de Photogrammétrie par AliceVision/Meshroom pour l’Industrie”.
This support will strengthen the project’s development, expand its features, and foster industrial collaborations. Integration within the CNRS 3D-HN consortium will further ensure that AliceVision’s technologies are shared and adopted by a broader scientific and technical community.
This partnership marks an important step toward advancing open, collaborative, and high-quality 3D reconstruction technologies for research, culture, and industry.
New version of Meshroom 2023.1 with new Color Management, improved 3D Reconstruction and Panorama pipelines.

Carsten Griwodz, Simone Gasparini, Lilian Calvet, Pierre Gurdjos, Fabien Castan, Benoit Maujean, Yann Lanthony and Gregoire De Lillo have been awarded to Best Open Dataset and Software Paper Award at MMSys 21 for the publication “AliceVision Meshroom: An Open-Source 3D Reconstruction Pipeline“.
AliceVision Receives Epic MegaGrant to Boost Open-Source 3D Reconstruction
We’re thrilled to announce that AliceVision, the non-profit organization behind the open-source photogrammetry framework and Meshroom, has received an Epic MegaGrant from Epic Games!
This grant will accelerate our mission to democratize photogrammetry by improving the Multi-View Stereo (MVS) component of AliceVision—making 3D reconstruction faster, more reliable, and easier to maintain.
Our focus is on enhancing the readability and performance of the MVS code, profiling current bottlenecks, and optimizing the depth map estimation process—one of the most computationally demanding stages in 3D asset creation.
With Epic’s support, we aim to deliver a smoother, more interactive experience for creators and researchers alike, bringing high-quality 3D digitization to everyone.
