    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.

Star pulse #sphere

u/deobfuscate

I cannot explain with words how cool this is.
u/donbright

if i undersand it, the "twinkling" really adds alot. they aren't all the same size of white particle?
u/rodrigo.siqueira

The "twinkling" is given by the particle size (2 last parameters of x.clearRect). Pixel size is defined by 3*S(i)+1, so it's between "3+1" and "-3+1" and the "i" makes it almost random for each pixel. An extra twinkling effect could be made by adding "t", but I thought it would be too exaggerated. You can try by changing to: K=5*S(i+t*4)
