You are doing geometry processing, you need precision, performance, and easy compilation on Linux/Mac/Windows ?
My fork of the mini-gmp lib is available here:
github.com/BrunoLevy/mi...
Use it wisely ! (with great power comes great responsibilities...)

github.com/BrunoLevy/le... has just reached 3000 stars on github.
What is it ? a hand-on tutorial to learn processor design with FPGAs.
In a couple of evenings, you will create a full-fledged Risc-V.
Why would I want to do that ? Why not !!

RING meeting in Nancy,
Cyprien Plateau--Holleville presented presented his awesome work on exact integration of the differential quantities involved in Partial Optimal Transport. And that's not all: It comes with a combined physsim - Optimal Transport - rendering on the GPU !

Hichem's method first creates a superset of the Minkowski sum (first image) that needs to be cleaned (second image). For the cleaning phase, my algorithm in dl.acm.org/doi/10.1145/... seems to work reasonably well...

Our article "Large-scale semi-discrete optimal transport with distributed Voronoi diagrams" (with Nicolas Ray, Quentin Merigot and Hugo Leclerc) just got accepted by Journal of Computational Physics. Pushing the limits of Optimal Transport by several orders of magnitude !

Mesh intersection algorithm (dl.acm.org/doi/10.1145/...) just got faster !
... Nice, but ...
... does it really work ?
Let's put it on the testbench.
