New #webGL 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

} // 122/140

    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.

drop in a t*=3; to hurry it up. change "with(g." to "with(c, " while remixing. change c back to g before posting.

safer for editing #webgl

u/IV

manga's original is grand, this is safer than my previous attempt in terms of editing and not getting errors which cause a reload :)
u/IV

the prblem with this is that youd have to clear both contexts which costs more bytes

I've no experience with webgl but it seems like you need twenty lines of code to draw a square...
u/katkip

That's true
u/New_Core

I've no experience with webgl either.. but saw you could do a square just adding: enable(SCISSOR_TEST),scissor(200,200,400,500) ..to clear a rect in that pos and size ..
