how to put 2d starfield in intro?

category: code [glöplog]
Hi guys, i was wondering how on earth can I put a 2d starfield like this one
--> http://www.pouet.net/prod.php?which=14559
into my intro? I hope I have the theory correct ---

- Generate lots of random numbers
- get some co-ordinates from those numbers
- move those co-ordinates into memory
- draw pixels/lines at the co-ordinates
- every time timer clicks, increment X coord and draw to buffer

Could anyone give me some source on how to do this with DIB, especially in MASM32?

Thanks :)

By DIB you mean GDI?

if you can draw a circle, you can draw a 2d starfield! :P
There's plenty of stuff on hornet, e.g.: http://goo.gl/AAKx0

tomaes: FWIW, I discovered the "les bp, [bx]"-trick while tinkering with pascal's 20-byte starfield. you can get a 19-byte starfield by replacing the 3 pops at the start with "lds cx, [bx]" :)

2d starfield = random dots moving in the same direction at slightly different speeds.

@xTr1m, go on
that 20b (or 19 now) starfield is insane.

@el generalissimo : i haven't link, but sn0w32 intro are more crazy)
For me, the ridiculous part of that 20 byter is the super cheap'n'dirty PRNG. :)
