it's interesting how often ideas come to me when I'm sitting in silence at a park/garden/forest.
I realised a very efficient and minimal way to do tile-based shadow-casting (in C) that's completely software rendered - not using the GPU at all.
this draws in <1ms

PEP: Prediction-Encoded Pixels
This format is able to compress images (up to 256 colors) smaller than GIF, PNG, QOI, BMP, in almost all cases.
A lot of passion and research (and fixation) has gone into this:

3 years ago I had an idea to make a metaprogramming language that would utilize TCC's near-instant compile times to also act as a scripting language.
last night I finally realized the final piece to make it work...
it's Python-like, via a macro-abstraction.

when anyone complains about C and how it's easy to make mistakes, I just think about this moment from 'The Incredible Machine' from 1968.
the computer never makes errors, it is doing exact what you told it to do.

main thread rendering at about 800fps,
second thread (the one that does all the collisions, bucketing, and motion) at 120fps.
the idea is that you'll never actually need to have this many entities at once, but hept can at least handle it well~
