C Programming: Rotating Cube with ASCII Graphics

The given code is a C program that renders a rotating cube using ASCII characters.

'The program uses the concept of 3D computer graphics to calculate the position of each vertex of the cube on a 2D screen and then maps the vertices to the corresponding ASCII characters based on their depth (z-coordinate) to create a 3D effect.

'The cube is defined using an array of vertices and faces. Each face is defined by four vertices and a normal vector. The cube is then rotated around the y-axis by incrementing the 'time' variable in each frame.

'The 'renderFrame()' function initializes the cube's vertices using a transformation matrix and then loops indefinitely to calculate the position of each pixel on the screen. It uses a z-buffer algorithm to determine the depth of each pixel and assigns the corresponding ASCII character based on the depth.

'The 'main()' function calls the 'renderFrame()' function to start the rendering process.

'Overall, the program creates a simple 3D rendering of a rotating cube using ASCII characters in the console window.
