    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.

An attempt at Truchet’s Tiles, but with vector graphics

This reminded me of a book I have named "The black art of 3D game programming" and it does cover vector graphics. Its also from 1995 so its DOS programming

i had to golf this code to get the original d/19898 under 140, but lost the "focal point" effect achieved here. In need of a shorter way to compute the (euclidean) distance from the focal point (defined by "d" in the code).
u/smtsjhr

please excuse my poor etiquette for i have now learned about code blocks and replacing EVAL with THROW to display compressed code, and the Discord for chat : )

nice!
