Yup! The library itself is .NET Standard 2.0, so it'll run anywhere with a supporting runtime. The only issue is that some older JITs don't understand the SIMD intrinsics and will either barf or run 100x slower.

Thanks! XNA and its descendants have definitely had a big impact. (I remember early on sketching out the development plan for v2 and coming up with like 9 months of work... Things escalated.)

That's a good question. It almost wasn't; there was a period post-WinRT, pre-"microsoft open sources everything" where investing a huge amount of effort in the ecosystem didn't seem like it would make sense. I did c

To make things a little stranger, it's worth mentioning that I'm not sure if bepuphysics v2 works well with Unity right now. Attempts in the last several months by users trying to upgrade from v1 to v2 had... less than ideal resul

Unity is in the process of moving more of their codebase into C#, backed by some in-house compiler work, yes. And they did indeed use C# extensively before then for game scripting, even if not exactly 'pure' or high performance in

I included that for a couple of reasons: 1) It's unusual. Historically, C# is more of a businessy thing, with a bit of game stuff on the side, mainly in the form of scripting. Extremely high performance C# code is even stranger. 2) It&

I know some people are fiddling with it, but I'm not aware of any public projects using v2 yet. It's pretty darn early still- convex hulls got added only a few weeks ago. I did build it for a reason, though- over the coming weeks

I'm glad someone respects newt rights.

I feel a little gross about headlining aggressive benchmarks with other engines, especially since most of them are free and open source just like bepuphysics. Plus, I learned a lot from projects like bullet, box2d and friends. I'd reco

I wouldn't exactly consider myself optimistic about safe general AI either, but there are extremely strong incentives in the direction of developing greater generality. Not sure we have the luxury of not having some form of AGI in our

'Safe' AGI is a harder problem than 'any' AGI, so getting started early could be helpful. Especially considering how bad many of the AGIs in the 'any' category could be. Worst case, we don't get a mulligan

Yup, that's definitely true. It's going to be a fun transition period.

It's true that features of similar or greater complexity do tend to work pretty well already, but those features tend to be the ones that are practically fundamental and used everywhere. (edit: but I have hit bugs with scheduling too-

by rossnordby 8y ago
The likelihood of a feature being functional is usually based on two things: its hidden complexity, and how frequently used it is. HW ray tracing suffers on both of these counts (for now). It won't be truly common outside of major engi

Seeing the intrinsics APIs get filled out- in the open, no less- has been pretty exciting. The fact that something like AES would be implemented competitively in C# is not something I would have predicted even five years ago. It's rema
