After seeing its announcement a few days ago I didn't think much of it, but after looking into it a bit this looks awesome !

Box3D was released a few days ago by legendary developer Erin Catto accompanied by a blog post, this is the person behind the popular Box2D engine.

In the blog post he explains that his work stems from his collaboration with Dirk Gregorius, "Principal Software Engineer II and Physics Architect" at Valve, the person behind Half-Life: Alyx's physics engine "Rubikon", which Box3D is based off.

Facepunch has also revealed that they have been using Box3D for about a year now as well in s&box. Showcasing a cool demo

An interesting quote from the blog post:

On the Valve side, Rubikon continues to evolve and Dirk has developed optimizations (similar to those in Box3D) in a new engine called Ragnarok. Look for that in future Valve games.
