We've been working on this for years 📈

Mesh intersections is hard ! Three years of agonizing pain summarized in my article that just got accepted to ACM Transactions on Graphics

dl.acm.org/doi/10.1145/...

The implementation and the expansion-based arithmetic kernel are available in geogram: github.com/BrunoLevy/ge...

New video of the Applied Algebraic Topology Network (AATRN): Mathieu Carrière (www-sop.inria.fr/members/Math...) talks about "Diffeomorphic interpolation for efficient persistence-based topological optimization."

Slides for a general introduction to the use of Optimal Transport methods in learning, with an emphasis on diffusion models, flow matching, training 2 layers neural networks and deep transformers. speakerdeck.com/gpeyre/optim...

Ho ho ho !!!
New versions of:
- geogram: the award-winning library, with remeshing, Delaunay, parameterization, CSG... github.com/BrunoLevy/ge...
- OpenNL: solve large sparse linear systems, multi-GPU support, github.com/BrunoLevy/ge...
- Graphite: GUI around geogram github.com/BrunoLevy/Gr...

My deep learning course at the University of Geneva is available on-line. 1000+ slides, ~20h of screen-casts. Full of examples in PyTorch.

New version (v1.9.1) of Geogram, the award-winning geometry processing library is out !

New in this version:

- much faster (2x speed) large-scale periodic Delaunay triangulation and power diagrams

- Linsolve/GPU: AMGCL + new nlCuda backend goes brrrr !

The paper on data-race-free OCaml is out! If you want to learn more about the zoo of new mode axes (contention, uniqueness, portability, ...) and cool new abstractions like capsules, it's all there!

Yeah here's my geometry processing starter pack. I hand-picked researchers and practitioners either in geometry processing or not, and some people are definitely missing so,
