Summary

Rockstar🎓
Top SchoolGuillaume Buisson is a veteran software engineer and CTO with 11+ years building high-performance graphics, image-processing and photogrammetry systems for film, VR/AR and large-scale visual installations. He has led architecture and engine development at Ubisoft (Vertigo/Shining) and now designs semi-automated video-mapping pipelines for complex façades at LOTCHI, combining algorithm design with production tooling. A pragmatic C++/Qt/OpenGL specialist, he has applied his skills across real-time rendering, path tracing, and XR platforms, and contributed backend improvements to the well-known AliceVision photogrammetry framework (mesh masking, visibility and caching). He pairs R&D rigor with product focus—shipping features from secure B2B clients at Dashlane to immersive experiences at DreamCorp—and regularly brings low-level optimization and cross-platform pragmatism to teams. Notably, his background spans both hardware-accelerated rendering and practical deployment concerns like mask undistortion and cache management that bridge research and production.

Contributions summary:Guillaume primarily contributed to the `meshMasking` program, which appears to be part of a photogrammetry pipeline. Their work involved adding functionality to mask and filter mesh vertices based on visibility criteria derived from image masks. This included implementing mask loading, visibility computation, boundary smoothing, and incorporating options like mask undistortion. Furthermore, they refactored code to use data from dense SfM data and implemented a cache system for mask management.
