Rockstar🎓
Top SchoolMathieu Westphal is a C++ software engineer and VTK/ParaView expert with 13 years of experience building visualization and graphics tooling at Kitware and in research environments. As co-creator and maintainer of the fast, minimalist 3D viewer F3D and a regular contributor to ParaView, he blends deep backend C++ skills with practical UI improvements and broad format import support across 3D model ecosystems. Based in Villeurbanne, France, he has driven features from robust file importers (3ds, obj, glTF) to nuanced ParaView enhancements like ArrowGlyph improvements and better UI handling for information-only widgets. Trained at ENS Lyon and INSA Lyon, he pairs rigorous academic foundations with long-running open-source stewardship, often solving interoperability gaps that make advanced visualization tools more usable in production.

Fast and minimalist 3D viewer.
Role in this project:
Back-end Developer
Back-end DeveloperContributions:58 releases, 3615 reviews, 631 commits in 3 years 4 months
Contributions summary:Mathieu primarily contributed to enhancing the 3D viewer's file import capabilities. They implemented a `vtkF3DMetaReader` class capable of reading various 3D file formats like `.vt*`, `.ply`, and `.stl`. Further improvements were made by integrating dedicated importers for formats such as .3ds, .obj, .wrl, .gltf, and .glb. These additions extended the software's ability to handle a wider variety of 3D model file types.
