    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.

#waves on a #perspectives #sphere -- #d3 #pointcloud

u/f8f82804

this dweet uses a better perspective transform based on Math.hypot -- #hypot
u/f8f82804

The projection still isn't perfect, because I'm rotating the sphere's axis towards the viewer by positioning it below the camera. The resulting distortion is approximately corrected by scaling the Y coordinate with /.9.

u/magna

Awesome technique! You could potentially add a way to "seed" the generation with a number and then search for a seed that resembles the Earth the most using brute-force.
