 * This application creates a 3D scene containing a textured cube and a dynamically generated

 * mesh based on input parameters. It showcases the handling of 3D transformations, animation,

 * camera movement, and basic input from the keyboard to manipulate the scene. Additionally,

 * it includes a real-time FPS counter overlaid on the scene to monitor performance.
