LECO - Unicode Bitpacked

u/tomxor

This is actually 115 bytes so only an 11 byte reduction over hex encoding, because each of the 10 codepoints takes up 3 bytes each when utf8 encoded, (over the wire, in the DB or in a local file)
u/dee-gomma

Top!
u/NiVZ

Loving seeing all the remixes. I've had another observation. The top left and bottom right segments are always filled. That means the binary can be reduced from 15 bits to 13 bits. Or a max value of 32,767 to 8,191. Would that help to compress things further?
u/tomxor

@NiVZ redundancies are a good thing to look for, but the tricky thing is figuring out if it's worth the extra code to pull out the info from the other side, sometimes you just gotta try and see if it saves bytes.

#FDTD #Electromagnetic Sim - Rendering #Poynting Vector (EM Flux)

Show more comments…
u/tomxor

I don't really understand maxwell equations, I just wanted to see if I could fit an FDTD into a dweet, and the Poynting vector of the EM field flow looks kinda cool.
u/tomxor

It's essentially a 2D sim of a point oscillator in a reflective box (although technically left and right wrap around), it has absolutely no physical equivalence, all parameters are normalised and tuned for visual preference.
u/ximavus

basically waves bouncing in a box? This visualization is really good though
u/cantelope

oh. well if has no physical equivalence then...
u/tomxor

I just meant that it's more abstract, because FDTD is commonly used to simulate a particular thing in real life.
u/ximavus

yeah waves bouncing in a box is the only way I understand it its a lot more complex than that

Solitaire win screen - Procedural version

u/lewdev

That's amazing! You got 4 stacks of cards and had them randomly shoot out at random velocities, which is much more accurate to the original win screen.
u/tomxor

Thanks :D glad you noticed, I actually counted the L/R directions from videos to check the probability 3/4 left, but the velocities were mostly eyeballed. I also tried implementing with the full set of unicode cards, since they have a nice codepoint arrangement, but fromCodePoint just costs too much, and they are transparent, your choice of the joker was spot on visually.

Its the new trend!
