giving the impression of an endless repeating scene

Hi there, basically i wanna make a scene that infinitely repeats in all directions, can anyone give me a clue how? or maybe just pointing me to some links, thanks!

almost forgot my simplest concept is when the camera view reach the end of level/scenes it should automatically draw the opposite view of the scenes, but that just for the camera.

try this way :

-load the worldmap or the world mesh 4 times;
-make as the current world the containing camera world;
-make camera range less than size_world/2;
-get each frame the camera position resulting which quadrant it is in;
-position the others world at the corresponded quadrant;
-when the camera passes outside of the current world, make the current world the world containing actual camera position;

take a look here:

yeah it's work, but i guess we'll be lack of performance if we load a huge scene...don't we?...hey, how 'bout this, if we place camera on each quadrant(near each border end), and true we need to reduce the camera farValue, so we only need to switch which camera is active.....????(yeah something like that...

) maybe it will give the same result....thehehehe...thanks dude!

this it is not a good idea for a huge map, it is to simulate a huge map, scrolling others smaller maps

indeed my friend, my mega super bbrain acknowledge that, but i'm to brilliant to do that....so any advice on how to do that

well at least some method, if you don't mind....

I personally wouldn't suggest a sphere, unless you actually want a spherical effect
To create a seemingly flat plane you'd need a pretty huge sphere, and it would be a much worse pain to manage than a paged terrain for example

weww...maybe you're right, but then what you're best approach then? i try to create 4 camera and additional 1 camera, but found problem with the sky when i switch the camera

If you're looking for a completely open terrain this could become a problem, if you'd pose some limitations on where you could go on your terrain you could use a streamed terrain which repeats after a while

"streamed terrain?

" don't know that yet.....but i think i'll try to cover that later or if i've got a dead end...anyway thanks a lot dude, that give me another option to try!

It's a technique of loading and unloading parts of your terrain from disk when needed, it can be hard to do without bottlenecks but it can produce huge terrains without memory overhead, and could be adjusted to support repeating terrains

Is there a tutorial on streamed terrain somewhere ??
It sounds like what I may need to try on my server side proggy

Hmmm....sound interesting, would you mind pointing to some link, uh..oh i mean not the whole source code, but the main concept.....(well, some example will be nice too

), i really appreciated if you do that...thanks again dude!

I believe the DirectX SDK has a sample implementation of a terrain streaming mechanism, you could always check that out

i see, although i'm not to friendly with DirectX, guess i'll check up that too....many2 thanks dude
