Readit NewsI think hacker news manages to be ok since it doesn’t rely on advertising which makes it much more palatable.
Hey, do DSPs have special hardware to help with FFTs? (I’m actually asking, this isn’t a rhetorical question, I haven’t used one of the things but it seems like it could vaguely be helpful).
So you could presumably also write a Lisp interpreter AND a Forth interpreter using it?
(Might as well write a Turing machine interpreter too for the trifecta... assuming one can decide on the syntax...)
That plus some additional functionality to make it more usable in the general sense (adding math functions, string manipulation, maybe some basic I/O) and it might be a VERY interesting instructional tool.
I've heard the term "thunk" but I forget what it means...
int a=1, b=2; auto thunk = [=]() { return a+b; }One of the authors of PhastFT here. Thank you for your interest.
We went out of our way to configure FFTW for AVX-512. The Rust bindings don't do it, but the FFTW itself in the benchmark does.
It's worth noting that with FFTW you have to choose between building it for your CPU and making it non-portable, or targeting the lowest common denominator of CPU features so that it runs everywhere but much slower. Meanwhile PhastFT detects the available CPU features at runtime, and will utilize the fastest CPU features without sacrificing portability.
Lastly, we are currently working on support for interleaved format [1]. That should ship in the next release.
1. It's been my experience that distros don't configure AVX properly for it, and
2. PhastFT takes its inputs de-interleaved in separate real/imaginary arrays which is generally not how complex data is provided, so that overhead doesn't appear in PhastFT.I'm guessing that adding physics, collision-detection etc. on top of this is non-trivial compared to using a mesh?
But I feel like for stuff like tree foliage (where maybe you don't care about collisions?), this would be really awesome, given the limitations of polygons. + also just any like background scenery, stuff out of the player's reach.
