-Idea is to implement 3D engine that can run world with unlimited

-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

** Swapping 3D engine
-TODO: description goes here ...
+This QBasic program is a 3D wireframe rendering engine designed to
+render potentially infinite 3D worlds. It achieves this by dynamically
+managing world data through a partitioning system that loads and
+offloads cube-shaped fragments of the world into and out of RAM as
+needed. This allows for the efficient use of memory, making it
+possible to explore large virtual environments without excessive
+resource consumption.
+
+World data is stored on disk, and only the necessary parts are loaded
+into RAM, allowing for the potential rendering of very large worlds.

** 3D land
+This QBasic program creates a visually engaging 3D shaded landscape
+with perspective and distortion effects.
+
+The program loops through each point in the grid, applying a cosine
+distortion based on the distance from the center of the grid. This
+creates a wavy, undulating effect across the landscape. Perspective
+transformation is then applied to give the illusion of depth.
+
+The transformed coordinates are used to draw quadrilaterals, which are
+filled with colors that alternate to create a checkerboard pattern.

** Anaglyph
-TODO: description goes here ...
+This QBasic program creates a real-time anaglyph projection featuring
+bouncing cubes. Cubes are created and placed within a 3D space. Each
+cube has its own position and velocity, which determine its movement
+and interactions within the environment.
+
+Anaglyph images are used to provide a stereoscopic 3D effect when
+viewed with glasses that have two different colored lenses, typically
+red and cyan. The program provides insight into how anaglyph images
+work, which can be a fun and educational project for those interested
+in stereoscopy and 3D visualization.

** Ray casting engine
-TODO: description goes here ...
+This QBasic program is a real-time 3D rendering engine that uses a ray
+casting technique to create a dynamic 3D landscape. The landscape
+includes various features such as hills and towers.
+
+Real-time Rendering: The engine adjusts the rendering quality
+dynamically to maintain a constant frame rate of 10 frames per second,
+ensuring smooth performance even on older hardware like an Intel
+Pentium 200 MHz in DOS mode.
+
+Users can move around the landscape using arrow keys and other
+specified keys to turn, look up/down, and even jump.
