    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.

strange... if you copy to new dweet area both d/11831 and d/11832 works (anyway exceptions still occurs, and it is the quine on each browser)
