welcome to the cyberpunk future

it's so fucking annoying that any time you try look for papers or whatever about calculus/algebra it's all llm stuff. like, no im not actually trying to learn about anything above 5 or 6 dimensions thanks. auto social engineering malware sucks

wire mother @echo.northsky.social · 8h

correction: linear calculus is boring. i could fw complex calculus. i WILL learn your ways mr clifford

i wanna understand category theory so bad dawg

wire mother @echo.northsky.social · 8h

should have paid more attention in maths class. abstract algebra is rad, but calculus is kinda boring

one day I'll figure gf2 coz i just know there's gotta be a non-cryptography use for it like smth with raster bitmaps. maybe some kind of binary NURBS or smth

my downfall will probably be my aversion to using any code I don't understand. i love a succinct algorithm, but will spend lots of time figuring out exactly how it works to the point i can reproduce it from first principles. unfortunately i love theory much more than experimentation

wire mother @echo.northsky.social · 8h

going for smth like what if caves of qud/dwarf fortress/rimworld was on an unstructured mesh for a sphere/ring/disc world. but at this point more just a tool than a game (that'll hopefully come later)

wire mother @echo.northsky.social · 8h

with procedural generation stuff (like wave function collapse)

wire mother @echo.northsky.social · 8h

at this point, it's basically a geospatial library for fictional (gamedev) data

wire mother @echo.northsky.social · 8h

but gray curves aren't continuous (same with morton). the hilbert conversion stitches it together to make it continuous. which makes KNN search much more efficient with guaranteed locality

wire mother @echo.northsky.social · 8h

and gray curves (gray code + morton) are a simpler intermediary to hilbert curves. hilbert just adds local transforms to convert from gray index to hilbert. inverse gray coding is more expensive than forward tho. fwd is just y = x^(x>>1)

wire mother @echo.northsky.social · 9h

i drew from this code a bunch, but added some SIMD optimisation and wider bit capacity. but the morton-hilbert transform is not bit width dependent

wire mother @echo.northsky.social · 9h

if ur interested, z-curve/morton (bit interleaving), which can then be bi-mapped to hilbert curve with LUTs. you can see some code here (links to explanatory articles in the readme) github.com/rawrunprotec...

must remember that i never actually make anything without a defined objective. and "but i wanna play with it" is not one

wire mother @echo.northsky.social · 9h

no echo, you do not need to make a lisp. it is not relevant to anything you're working on no matter how much you want to play with NaN boxing

wire mother @echo.northsky.social · 9h

I've been reading too much abstract algebra theory coz it took me a minute to remember cardinality isn't just about infinities

wire mother @echo.northsky.social · 9h

well i guess it's "indexing" then? its nD to 1D in any case (space filling curve)

wire mother @echo.northsky.social · 9h

and with 3d points it's like, oh o got a whole extra 32 bits i could use there. looking to see if using that for vector magnitude improves locality for volumetric data. at the least i can use it for layer/height sorting (not interleaved with xyz) but multi layer locality would be cool

000

wire mother @echo.northsky.social · 9h

that's just a order encoding rly

100

wire mother @echo.northsky.social · 9h

does it even count as a hashing algorithm if it's bijective?

wire mother @echo.northsky.social · 9h

particularly with the hash being invertible

000

wire mother @echo.northsky.social · 9h

but probably good to minimise indirections. tho with the hashing, it should be fairly local memory access regardless, so cache misses shouldn't be a major issue

wire mother @echo.northsky.social · 9h

re: working better with triangulations, that's mostly just about having consistent 3-edge vertices instead of variable, which allows for some nice optimisations. but not particularly necessary with half/quad/winged edges

100

wire mother @echo.northsky.social · 9h

tho, i would like to investigate mixed area/radius cells with WFC. could be interesting

100

wire mother @echo.northsky.social · 9h

spatial hashing + quad edge rhombille should be plenty performant for WFC. don't see why the need for hex grid rhombilles. any delaunay/voronoi grid should work with area/radius constraints. and those constraints are implicit with poisson point gen, so doesn't require much

100

wire mother @echo.northsky.social · 9h

why are edge duals not more of a thing? quad edge meshes are basically canonical mesh structures already, implicit quads already there.

100

wire mother @echo.northsky.social · 9h

looking forward to confirming rhombille/quad tile generation from arbitrary polygon meshes by using edge vertices + adjacent face centroids. can't see any reason why not, and will mean unstructured grids can produce quad tiles. should work especially well for triangulations, but any poly works

100

wire mother @echo.northsky.social · 9h

need to test but should be good for approximate hamilton paths too (hilbert indexing), which is very useful for fast point/face loop detection

wire mother @echo.northsky.social · 9h

now quad/oct trees can all be implicit

wire mother @echo.northsky.social · 9h

spatial hashing code completed, with some simd optimisation to boot 🙂‍↕️

godzilla doesn't need to rely on a respiratory transport system because he has a reactor inside him (he needs to expel a lot of excess heat tho), but what about the other kaiju? do they all use some fission based anaerobic respiration? perhaps mothra's wings are giant tracheole networks?

if you found yourself in some kind of honey i shrunk the kids or downsizing situation, you'd probably just be high as fuck all the time from nitrogen narcosis

their respiratory capacity would be insufficient due to the square-cube law

the non-spherical stuff will actually be easier to implement tbh. no weird patch boundaries to deal with

ok, so my game project is sorta becoming a geospatial data tool for fictional worlds (with options for different topology like discs and rings) maybe it'll just be a tool

what if we just punched a hole straight through the earth along the polar axis, just so it was easier to project onto a grid
