    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.
    x: A 2D context for that canvas.

u/sigveseb

waaa with texturing! awesome!
u/tomxor

Thanks :) I just realised I missclassified these. Although it is 2.5D with 3D texturing as Wolfenstien/Doom pioneered, the 2D distance is found using #raymarching rather than casting, which is necessary for size and implicit surfaces.

The lack of x.fillStyle is amazing.
u/pavel

Save 3 chars by incrementing Z by .1 instead of doing the math every time: A=S(t);B=C(t);for(c.width=X=128;X--;x.fillRect(X,36-125/Z,Z**.5/7,250/Z))for(Z=0,R=T(X/81-.8);(A*t+24+(R*B-A)*Z^64+(R*A+B)*Z)%15>1;)Z+=.1
u/tomxor

Ah yes! thanks pavel :) I did try to get rid of Z/8 once but didn't go far enough with the constants as you did.
u/tomxor

Can also now play with the marching granularity more easily to get smoother results... although it's very slow without an SDF for the fractal for larger initial steps.
