SYCL is probably the most up-to-date CUDA alternative for all intents and purposes, at least if one likes modern C++ style (and lambdas inside lambdas). Expose it as C and get bindings to any other language for relatively little effort as well since it’s just C++. With AdaptiveCpp you can also compile SYCL to CUDA so both ways work with the CUDA dialect (PCUDA).

SYCL, as well as AdaptiveCpp, is a relatively active project though and has been for several years, feeding into the C++ standards committee work and is supported by several large organisations, including US national labs and several European universities. I suppose it’s worth keeping track of for people in related fields.

I suppose it’s just really hard to beat the head start and ecosystem integration NVIDIA has with CUDA.

Very nice project! I have played around with it for a while and noticed that the top right satellite/debris selector doesn't seem to be working correctly as the "Satellites Only" and the "Debris Only" options don't seem to change anything on the ground track view.

I'm wondering if you have any information on Celestrak data licenses and usage terms? Their data comes from Space-Track (plus some directly from operators) which isn't very permissive with its usage and I never found anything more specific on Celestrak's website.

Reminds me of a space version of Flighty, best of luck with it!

I’ll preface this by saying I mostly use C++ and have just basic experience in Zig, but as far as I understand comptime is much more procedural than C++ templates which are more declarative. With templates you get quite good pattern matching through the compiler’s machinery, for instance through template specialisation, while Zig, in my understanding, requires these to be handled manually in code. Personally, comptime feels like constexpr/consteval in C++ but with the ability to interact with the type system itself. The significant downside of C++ metaprogramming is that sometimes many features interact weakly and feel very much tacked on top of each other while Zig’s looks more cohesive. Perhaps someone with more Zig experience can weigh in.
