u/noonat

~ is a bitwise not. It flips all the bits in the number to the opposite. Flipping again (~~) puts the bits back to what they were. It works does something similar to floor because it truncates floats to 32-bit integers as part of the operation. (But unlike floor, ~~-2.1 is -2 instead of -3.)

sierpinski triangle :D

It'd be nice to have a blog post explaining it :) (please?)
u/trupples

I didn't look much into it but it might have to do with a thing I read about once where if you have a point that "walks" half the distance towards a random corner of a triangle you'll end up drawing a sierpinski triangle sorta like you can see in https://www.dwitter.net/d/5097
u/trupples

And according to http://distrustsimplicity.net/articles/sierp… if you were to use 4 points instead of 3 you'd get a tetrahedron like in this dweet. Fascinating stuff
