New blog post: Relativistic Quaternions I briefly discuss what quaternions and dual quaternions must become in spacetime in order to represent physically meaningful motions. terathon.com/blog/relativis…

Lock-free, intrusive thread-pool in 200 LOC: gist.github.com/kprotty/17af8d… Submission is wait-free. Removed all CAS-loops outside ring buffer steal. Basically zap v2. Context: zig.news/kprotty/resour…

しずくシミュレータが遊べるようになりました！スマホ・PCからどうぞ oimo.io/works/drops/ "Drops" is now playable! Try it out with your smartphone or PC ...maybe source code available later?

I finally got graph coloring working properly in the solver with good performance. Now large piles can be solved on multiple threads in deterministic order. It really helps with stability. Big thanks to Erin Catto pointing me in the right direction!

Joints in the multi-threaded solver. While simpler to implement in theory, multiple violating constraints are much more sensitive to ordering, making them challenging for graph coloring.

Initial steps on integrating the blob system with the liquid system.

Herding cubes.

I'm working on a series of posts about Monte Carlo methods! The first (thenumb.at/Probability/) is a review/overview of continuous probability, including random variables, distributions, expectation, variance, probability bounds, and the Dirac delta.

Monte Carlo integration lets us integrate high-dimensional functions exponentially faster than traditional methods! Part two (thenumb.at/Monte-Carlo/) explores how and why it works.

New blog post! "Load store conflicts", in which we look at some performance sensitive code that has surprisingly dramatic performance swings based on the compiler and the microarchitecture used. RTs appreciated! zeux.io/2025/05/03/loa…

It's finally time to announce my game: Island Architect! Sculpt seaside towns in Island Architect, a relaxing builder inspired by coastal Europe. Build winding streets, whimsical towers, or calm fishing villages in this cozy experience. Wishlist now on steam!

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/10.1145/37… The implementation and the expansion-based arithmetic kernel are available in geogram: github.com/BrunoLevy/geog…

I think this might actually be the must unreadable code I've ever seen Something about the underscores and the parens makes my brain not able to read it

tell me again about how locked in you are
