I’ve wanted to do this particular kata for a long time and finally got to it.
There are some post hoc notes I’ve written down if you’re interested in reading stream of grumpy remarks (with the pictures of the intermediate steps!).

Thank you for your contribution. I enjoyed it completely. I love that you used massiv I think that it is a awesome library that demonstrates Haskell’s laziness allowing fusion and control over evaluation for parallel and concurrent programming. I’m not gonna lie geomancy is really giving me some SIMD envy. This is a good example of Haskell’s numerical strengths. I hope to contribute in this way more in the future. I also hope to see more contributions from you.
Found out there’s a gotcha then adding multiple
-with-rtsoptsargs in a package. Had to collect them into one pile of- '"-with-rtsopts=-s -N -A64m"'to avoid the repeated overwriting of it. Gotta check the rest of my packages for this…
This is #18117: It's not possible to specify multiple `-with-rtsopts` flags · Issues · Glasgow Haskell Compiler / GHC · GitLab, it might be helpful to chime in there.
The
intervalclass is just a pair of numbers, with extra functions. I briefly dived into Hackage archives, but the solutions are way to complex for the task.
There is indeed a zoo of libraries for intervals on Hackage. As a maintainer of data-interval: Interval datatype, interval arithmetic and interval-based containers, I’m curious if you can identify any possible improvements.
I ended up removing the Interval entirely. It was only needed to find the closest positive hit (if any).
The next book has BVH building chapter and I’m going to take data-interval for a walk.

What’s the next book?
Next two books, actually…
- RTOW - the basics
- The Next Week - optimization and advanced materials
- The Rest of Your Life - sampling intricacies
