i'm not seeing the connection between all kinds of stuff there. i'm not super-interested but if you do feel like having another crack at illustration, try imagining with 8 bit state var(s)

### Re: CMWC8II

There is a consensus that we should not use a generator's full period. There have been many proposals - one such is to limit to the square root of the period. interesting, though to the sqr seems extreme. maybe they suggest that to for simple design. yeah 2^32 is way too short what's this 2^30 in r...

i hope you find the right tooling to satisfy your needs. my Gen 4 accumulator is done. i now store a decently accurate floating point average in a byte. it's awesome. though in my random ray shooter, i discovered i'd "need" to track write counts per pixel, which Gen 4 "doesn't have en...

i often find myself sitting for minutes trying to word something so it's either somewhat clear and hopefully thoughtful. Writer's block. I get that. There are many ways to combat it. What works for me is to save what I have done and then do something else for a while. Very typically when I return, ...

i did a search on 1d sharpen, found a post mentioning origin [0 1 0] + sharp [-1 2 -1] but it doesn't do radon justice. i might have an idea of how to proceed next: make a delta of source and inverse radon, then analyze radon of that.  by "analyze radon" i mean compare a radon angle ...
