Still working on hashtag#geogram / geogram+ / Tessael boolean operations for meshes,
Making them faster without sacrifying robustness and generality.
More to come ...

Recently introduced, numerical methods for fluid simulation relying on Optimal Transport offer new guarantees as compared to classical algorithms. The fluid is modeled with a Lagrangian point of view,...
Chris Hanson put the source code to the Amiga Juggler demo (1987, by Eric Graham) on GitHub.

Recovering Eric Graham's 1987 Juggler raytracer source code AlphaPixel often gets involved with modernizing and updating old performance and graphics code. Sometimes that means client work under NDA. ...
Working with Cyprien Plateau-Holleville, Charles Dapogny, Edouard Oudet and Roya Mohayaee on shape optimization / partial optimal transport. A lot of work remains to do (in particular, Virtual Element method in 3D)
Preprint (2D version) here: arxiv.org/abs/2409.07873
Under the hood: HUGE Laguerre diagrams (fig 1), used to compute the large sparse matrices (fig 2). Grid 5000/SLICES has nice "pocket calculators" (fig 3), so we played with them and obtained interesting timings (fig 4) on a smaller problem (120 million points). Can we do even better ? More to come.
