New #stereograph dweets

function u(t) {

c.width=1920 // clear the canvas
for(i=0;i<9;i++)
x.fillRect(400+i*100+S(t)*300,400,50,200) // draw 50x200 rects

    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.

You can switch clockwise and anticlockwise rotation in your brain if you try hard

To tilt it downwards, change 540 to 540+99*S(a)

#stereograph #d3 donut, cross your eyes for a 3D effect

so cool
u/BackendForth

Nice!
u/magna

Nice! The z is inverted for me...
u/tomxor

Neat. Magna, are you uncrossing your eyes by any chance? :P (i.e making your eyes further apart)
u/magna

u/tomxor yeah! I've gotten used to relaxing my eyes and looking "afar", from the way SIRDS normally work. I don't I can cross my eyes without looking at something actually close to my eyes. I suspect most people are more comfortable with relaxing their eyes than crossing them...
u/smtsjhr

so fun!
u/joeytwiddle

If you are a person like magna, change: fillRect(w to fillRect(3*w and +w*j to -w*j

#stereograph Cross your eyes until the images are on top of each other for a 3d effect!

u/taupelink

whoa
u/magna

Nice! I relax my eyes (i.e. as if looking at a distance) instead of crossing. Then the smallar squares appear closer, not farther away. But amazing regardless! More of this technique please!
