    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.

#perspective #sphere #pointcloud #hypot -- the distortion from this projection is clear here, because the two spheres should be concentric but it looks like they aren't

u/metamero

this dweet series is great
u/f8f82804

thanks! I'm having a lot of fun with it. Hopefully I'll be able to fix up the distortion a little and reivist some of these ideas
u/f8f82804

the distortion here is pretty bad because i'm applying the correction incorrectly! see d/11812
