sorry i just noticed the title is wrong sorry

I'm wondering what i should do for my 3d world for a game I'm making.
I'm thinking of cutting it into segments so it will run faster. but i would rather one big world but how do i make a huge world with lots of objects not extremely laggy?

You can make a decently large world as one unit (at least on a computer with decent specifications). If you want it to be "huge" though, then you would probably have no other choice than dividing it into segments.

To limit the lag on large worlds, the two most important techniques are culling and Level-Of-Detail (LOD).

Culling involves hiding polygons that won't appear on the screen anyway. DarkBASIC will automatically cull individual polygons that face away from the camera, so the only thing you can do to improve this is use HIDE OBJECT or EXCLUDE OBJECT ON when objects go out of the screen.

Level-Of-Detail is the technique of replacing a model with different versions of itself depending on how close the player is to it. When the player is really close to the model, a high-poly version is present. As they move farther away, the high-poly model is deleted or excluded and a lower-poly one is shown.



Oh, and just for randomness, 3d words.
