    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.

Do Fall ! #game

u/tomxor

Use left + right (focus the iframe with mouse first)... If you hit the top, you die, if you fall too far, you die, if you fall too fast you fall through things, you die. High Score: throw u=B<0|B>72?u:t|0
u/tomxor

Forgot: If you fall just right, you live :)

Ray Marching SDF Sphere+Bumps

u/tomxor

Specifically, sphere tracing, with axis aligned field, i.e no perspective, marching along Z only. The sphere is not rotating, the simple displacement map is just being pushed through it's x.

#LargerThanLife #Automata Bugs Rule

Show more comments…
u/tomxor

The Larger Than Life "Bugs" rule R5,C0,M1,S34..58,B34..45,NM. You can introduce more entropy by adding spaces to the code (to restart) which causes i&1 to be combined with existing state in the rule's dead space.
u/tomxor

This uses a sliding window to efficiently compute the sum of arbitrary radi Moore neighbourhoods (i.e box blur kernels). It naturally wraps to the next line giving it a kind of twisted toroidal space, which takes less code and is more efficient since it is only necessary to initialise the sliding window once per dimension: O(2n+2r). The FPS is half of what is displayed since every other frame is used to sum the transposed sum of x.
u/tomxor

Other sized w must be a power of 2 and i must be at least w**2+r+1 (r=neighbourhood radius) to allow the sliding window to correctly initialise, otherwise a bad sum will propagate throughout the grid usually causing everything to die.
u/KilledByAPixel

👍 Thanks for the explanation!
u/tomxor

hmm the larger than necessary i seems to be introducing artifacts... change to i=w*w+6 if you want to see the pure rule.
u/katkip

Woow! I remember it from the The Powder Toy game
