Cool! Looking good! Like the animation of them...
Do you happen to have this as an expanded code to have a look at?

Wow! That is awesome! Too bad it's so slow...

You can change size and size1 to lesser multiples of 2 to make it faster, but I haven't figured out how to make it seamless... I'm sure it would be easy for Jukama...

Here'a a stupid question: What does x >> y mean? Is it a bitwise shift right like in C#?

This is the fastest way to get this without a shader.
http://forum.thegamecreators.com/?m=forum_view&t=145552&b=6

Here is my really fast version (dll is written in assembler).

sync on : sync rate 0 :randomize timer() : autocam off

color backdrop rgb(64, 64, 255)
set ambient light 35
ink rgb(0, 255, 255), 0

PerlinDll()
load dll "temp.dat", 1
 
rem image and noise size (128, 256, 512, 1024)
rem above 512 a update make no sens (not recommanded)
call dll 1, "PerlinMakeNoise", 1, 128

make object plain 1, 640, 480
move object 1, - 399
texture object 1, 1
ghost object on 1

rem interpolation line(0) oder cos(1)
rem cosinus is somewhat better (but slow)
call dll 1,"PerlinSetMode", 1

rem smoothing (1-5)
call dll 1,"PerlinSetSmoothing", 1

rem cloud cover (0-100)
call dll 1,"PerlinSetOpacity", 25

rem sharpness (0.50 - 0.99)
call dll 1,"PerlinSetSharpness", 0.95

repeat
    
    set cursor 0, 0
    print "FPS: ", screen fps()

scroll object texture 1, 0.001, 0.001
    
    rem noise updaten to next frame
    call dll 1, "PerlinUpdateNoise"
  
    sync
until mouseclick()

rem free all
call dll 1, "PerlinDeleteNoise"
end

`---------------------------------------------------------------------------------

function PerlinDll()
    if file exist("temp.dat") then delete file "temp.dat"
    open to write 1,"temp.dat"
    do
        read d$
            if not len(d$) then exit
            for i = 1 to len(d$) step 2
            write byte 1, GetByte(d$, i)
        next i
    loop
    dummy = memblock exist(1)
    close file 1
endfunction

function GetByte(d$, i)
    h = asc(mid$(d$, i)) - 48
    l = asc(mid$(d$, i + 1)) - 48
    b = (h - (h > 9) * 7) << 4
    b = b + (l - (l > 9) * 7)

You want it faster

:

PerlinSetSharpness 0.80

I think it's ok ...

42 fps using the assembler version. I am impressed, and wasn't aware you could do that sort of old school stuff in db. It reminds me of the old spectrum routines minus peek and poke, that I used to type in a short (lol) time ago. that's with an old geforce 7900GTX, and a quad 6600.
