I also did a similar thing with SmallVCM, another "educational" ray-tracer: https://github.com/yuriks/SmallVCM-rs https://github.com/yuriks/SmallVCM-rs There is also a written report with my experience and benchmark results, but unfortunately it's in Portuguese: https://github.com/yuriks/tg-yuriks-2014b/blob/master/final/preview.pdf?raw=true https://github.com/yuriks/tg-yuriks-2014b/blob/master/final/... One thing that surprised me a lot is that Rust ended up being noticeably faster than C++ (around 20%) even when compared with clang.

Do you mean compared to C++ compiled with LLVM (as opposed to GCC)? I've found that LLVM is generally faster than GCC and in some cases significantly so.

  Yes, I compared Rust and Clang using similar LLVM versions and the Rust version of the code consistently beat Clang.

    Not the same version then? :)

      For the moment Rust is using a custom fork of LLVM while waiting for its patches to be upstreamed.

        Hasn't this been the case like forever (at least for the past two years)?

        They keep coming up with new patches to upstream. :)
