    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.

3D #Lorenz Attractor 2

u/aleamb

#d3 #attractor
u/katkip

what is that rotation? clockwise or counter clockwise #illusion
u/katkip

not really 3D. the perspective is the save everywhere
u/katkip

it is 3D because the attractor is in space, but there is no perspective effect

Peter de Jong attractor. Changing the 1, 2, 3, 4 multipliers in the sine/cosine functions changes the shape.

Robbyg, here is a smaller version with higher resolution. Same equation, no need to create array: t||(h=X=Y=0);for(i=950;i--;) X=950+(S(1*Y)-C(2*h))*440, Y=550+(S(3*h)-C(4*Y))*230, h=X,x.fillRect(X,Y,1,1)
