rayon #18

Closed owenthewizard closed 2 years ago

owenthewizard commented 2 years ago

Would it be possible to add rayon support? Right now par_bridge can't be used because the iterators aren't Send.

You should be able to use .rows() iterator. Splitting parallelism per pixel is going to have prohibitively large overhead.

Big brain; thanks. 😣

Worked for my path tracer. Rayon is designed to split extremely small workloads. (But only if it knows the size up-front.)
