swapping 3D engine

-
-
-3D engine implements visibility distance, far away objects will be -swapped into hard disk to increase framerate and reduce memory usage. -Visibility distance adjusts automatically. - -This techniqe allows handling of a very complex world (for QBasic). -World is broked down to 100x100x100 units sized blocks, -and stored on disk into separate files. One file per -block. - -This is just an experiment to test out the idea, -world will be synthezied and constantly updated. -Engine allows user to freely fly around using mouse and keyboard. - -

-System requirements:
-	CPU 500 MHz or better
-	MS QBasic (preferably QB 4.5) in your path

Swapping 3D engine

+Idea is to implement 3D engine that can run world with unlimited +complexity. To overcome RAM limits and keep good framerate, world is +divided into cube shaped segments. Those segments are swapped out to +disk when they are too far away. When you move around the world, +segments are swapped in on-demand. +

+ +

+Engine allows user to freely fly around using mouse and keyboard. +

+ +

+Sexment size is 100x100x100 units. Every segment is stored in its own +file within the filesystem. +
