Hello,
i found it and SDL as nice approaches, bust as BrowserUk mentioned that it "... would require your computer to have approximately 226 PetaBytes of RAM."; because as i found out - "SDL_Init 65535", which means that it wouldn't even work for 100*100*100.
What considering PDL, i did a( maybe that's the problem) few testing which resulted not better.
Even on Windows platform, i serched for an app like Paint-Brush( because of its lurge x,y coordinates( something like 300,000*300,000)) but 3D, and found nothing.
I even hoped Macromeria products could evantually become handy for me, but than i found out how pourly coordinated they are.

If anyone can think of a comprihancive way to present such a Matrix,
please inform me.

P.S.: If anyone is inerested in what on Earth am i creating, i would more than glad to tell that i'm working on a matrix representation of the (Jewish) Torah (which has 304805 letters), and i what to "paint" each letter in a spesific colour, and so when i'll look-for a spesific word i'm more than sure that i'll see its (coloureful 3D) image among the letters ( when as if conecting the matching letters by lines - like drawing on stars).

It's an interesting idea, but even if you had the memory to hold it, you would need a 10,160 (80x127 grid) of the highest resolution LCD displays to be able to display a single slice through it. And that would be roughly 38 meters square!

At $8,000 a throw, that comes to around US$80 million. You might get a bulk purchase discount, but I doubt it would really help :)

On a more serious note, given that you are going to be unable to display the whole thing, or even a significant chunk of it in one go, it would be best to look at taking a different tack. Rather than building the whole thing and then displaying bits of it, you could build the bit you can display only, and then as you scroll around, you delete the bits that are leaving the screen and draw the new bits on the other side (top/bottom etc.). This is basically how those mega-world video games work.

That said, I am having great difficulty in tryng to visualise what it is you are attempting to display. Maybe you could try and explain using a limited alphabet (a-e?) and some ascii art?

test5.pl is very good looking

but an xyz space where i would be able to create coloureful dots by coorditates ?

As your dots are going to be colorful, you presumably intend for them to be viewed?

If so, how do you intend for them to be viewed?

P.S.: -304805 < (x=y=z)< 304805

To manage that volume of 3D space, assuming just 8-bit color, would require your computer to have approximately 12 226 PetaBytes of RAM. To put that into a rough context, according to one source on the web, that is roughly half as much again 30 times as much data as is currently available on the entire WWW put together.
