    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.

Schramm–Loewner evolution

u/Tesseract

If anyone knows how to get something that looks like brownian motion as a function of t in around 10 bytes, I'd like to know (it should replace C(t)).
u/rodrigo.siqueira

maybe C(t*i**8) is more random
u/rodrigo.siqueira

I see a very beautiful orange SLE (Schramm-Loewner Evolutions) here: http://www.statslab.cam.ac.uk/~jpmiller/teac… I wish this could be reproduced in javascript.
u/rodrigo.siqueira

I asked jpmiller about how he did that incredible beautiful orange SLE and got his answer, if you want to reproduce it The way that the image was made is using the following steps: "1) Sample an instance of the Gaussian free field (GFF) — see Page 24 of this paper for Mathematica code which produces it https://arxiv.org/pdf/math/0312099.pdf 2) The GFF is a function h defined on the grid {1,...,n}^2. If you consider its exponential exp(i c h), where i = sqrt(-1), c > 0 is a constant, then you get a vector field. 3) Then you can consider flow lines of this vector field by solving the equation eta’(t) = exp(i c h(eta (t)). The image essentially shows flow lines with angles +/- pi/2 starting from every point in the square where c = 1 / (2/Sqrt(128) + Sqrt(128)/2) — this is the value of c so that what you will see will be related to SLE with kappa = 128. Best wishes, Jason"

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.

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.
