I replaced pixels with rectangles and it works like it should. It's a little bit slow, though. It looks the best with 60fps, but only compiled languages can achieve that on my computer.

Code:
set window "Bubble Universe", 512, 512

r = 6.283185307179586 / 235

mw = 512

mh = 512

hw = mw / 2

hh = mh / 2

x = 0

v = 0

u = 0

t = 0

k = rnd(190) + 64

set redraw 0

while 1

    set color 0, 0, 0, 255

    draw rect 0, 0, 512, 512, 1

    for i = 0 to 255

        for j= 0 to 255

            u = sin(i + v) + sin(r * i + x)

            v = cos(i + v) + cos(r * i + x)

            x = u + t

            set color i, j, 255 - i, k

            draw rect int(hw + u * hw * 0.4), int(hh + v * hh * 0.4), 1, 1

        next

    next

    redraw

    t = t + 0.01

    k = rnd(190) + 64

wend

I'm far away from my home and computer, but it would be fun to see how it runs in n6.

RE: Draw pixel and alpha channel - Tomaaz - 02-09-2024

I tried, but a Linux version of N6 seems to be not working on my machine. I can't be bothered with installing the Windows version through Wine. Maybe someone who's got N6 and N7 installed on a Windows machine could check the difference in performance?

Well, with my eyesight, it still looks impressive! Yes, just a touch slower, but runs very well... Nicely done!
