sky spheres are too many polygons, an alternative would be a sprite drawn behind the 3d stuff, but that would mean you can't have other 2D stuff like buttons because they get drawn behind as well...any remedies for this?

How about a skybox instead? With the appropriate texture they can look as good as a skysphere ... and they only have 12 polys too.

yes but I will be needing a really big skybox because my matrix might be 100000 units... won't the polys increase a lot or will it still be fine?

you'll need a bigger texture me thinks, but the ploy's shouldn't increase, however having a skybox all around that matrix isn't necessary and it also means the player can touch the edge of your sky so if you make a smaller skybox but position at the players coordinates every loop, they are always surrounded by sky... yay!

you mean surround the player object and camera by the sky box and move it with them?

Ya dont make the sky so huge or your gonna have to have a really big BMP and high res for each plain on the sky box. Thats just gonna slow you down a lot. Instead I would do this.

Position the center of the skybox at the object coordinates (so the player is always in the center of the skybox and it moves with the object)

Set the fog on so you cant see those nasty lines where the skybox hits the matrix

but won't it be very obvious that there's a sky box around you? I mena it'll block out buildings and stuff behind it...
Would a sprite behind the 3D slow down the thing more than a big skybox?

skybox is the way to go, if you make it big enough so the buildings don't just suddenly appear but small enough so the texture doesn't have to be massive for it to look good then it'll be fine

hmm never heard of moving the skybox with the player cause at one point youll get to the edge of it which wouldnt look good if you move it say you walk to the edge the edge of the sky box want cover the matrix youll see the backdrop?

I always move position skysphere with to my camera position. I will check out the terragon to see if I can make a some nice textures, thanks Chris. Maybe I will try a skybox instead of a skysphere.

Alternatively you could use COPY BITMAP to paste a background bitmap to the 3D backdrop. Just load your background image into an offscreen bitmap (BITMAP 1 for example) and then use COPY BITMAP 1,0.

You could even use a lower resolution bitmap and scale it up as needed and it would always be behind your 3D objects. And if you're really ambitious you could scroll your background bitmap with the movement of the player or camera.
