🚀 Interactive Spaceship Controller (OpenGL)

An interactive, real-time 2D spaceship simulation built with C++ and OpenGL (GLUT). This project demonstrates core computer graphics concepts including 2D transformations, interactive UI rendering, and basic physics/animation.

✨ Key Features

• Advanced 2D Transformations: Smooth implementation of Translation, Rotation, Scaling (Zoom), and Shearing (Skew) using matrix operations.
• Sci-Fi Responsive UI: Custom-built overlay panels featuring rounded corners, alpha blending, and real-time telemetry updates (Position, Angle, Scale, Shear).
• Dynamic Environment: A continuous, auto-generating starfield background and a glowing celestial body (Moon) using GL_BLEND.
• Weapon System: Directional laser firing mechanics mathematically aligned with the spaceship's current transformation matrix (Rotation & Shearing).
• Responsive Design: The viewport and UI elements dynamically scale and reposition upon window resizing.

🚀 How to Build and Run

On Linux (Ubuntu/Debian)

1. Install the required OpenGL libraries:

   sudo apt-get install freeglut3-dev

2. Compile the project using g++:

   g++ main.cpp -o spaceship -lGL -lGLU -lglut

3. Run the executable:

   ./spaceship

On Windows

• It is recommended to use an IDE like Code::Blocks or Visual Studio with the GLUT libraries pre-configured.
• Simply add main.cpp to your project, link the OpenGL libraries (opengl32.lib, glu32.lib, glut32.lib), build, and run.

🧠 Core Architecture Highlights

• Main Game Loop: Driven by glutTimerFunc executing at ~30 FPS for smooth animations.
• Trigonometry & Physics: Lasers calculate their trajectory using sin() and cos() of the current rotation angle, adjusted for the shear factor.
• UI Rendering: Orthographic projection (gluOrtho2D) ensures UI elements remain perfectly aligned with the screen boundaries regardless of window size.
