OpenGL Airplane Animation

A lightweight 2D airplane animation built in C using OpenGL and GLUT.
The project demonstrates basic graphics programming, animation techniques, and modular scene rendering.

---

Features

• Gradient sky background
• Seamless, animated cloud movement
• Custom airplane model (body, wings, tail, nose, details)
• Smooth 60 FPS animation with timer-based updates
• Modular and readable codebase

Getting Started

macOS (Homebrew)

1. Install dependencies:

   brew install freeglut

2. Build and run:

   gcc main.c -I/opt/homebrew/include -framework OpenGL -framework GLUT -o airplane && ./airplane

Windows (MinGW)

1. Install MinGW and FreeGLUT binaries.

2. Place the FreeGLUT files:

   • Headers (freeglut.h, etc.) → C:\MinGW\include\GL\
   • Libraries (libfreeglut.a or .lib) → C:\MinGW\lib\
   • DLL (freeglut.dll) → same directory as the executable or in C:\Windows\System32\

3. Build and run:

   gcc main.c -lfreeglut -lopengl32 -o airplane.exe
   airplane.exe

Code::Blocks

1. Create a new empty project.

2. Add main.c.

3. In Build Options → Linker Settings, add:

   freeglut
   opengl32
   

4. Build and run.

Visual Studio Code

1. Open the project folder in VS Code.
2. Install the Microsoft C/C++ extension.
3. Use the terminal to compile with the commands provided above, or configure a tasks.json for one-click build and run.

Example tasks.json:

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "Build and Run Airplane",
            "type": "shell",
            "command": "gcc main.c -lfreeglut -lopengl32 -o airplane.exe && airplane.exe",
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "problemMatcher": ["$gcc"]
        }
    ]
}

Project Structure

• main.c — Rendering and animation logic
• README.md — Project documentation

Code Organization

• Independent functions for each scene element (sky, clouds, airplane, etc.)
• OpenGL primitives: GL_QUADS, GL_TRIANGLE_FAN, GL_LINE_LOOP
• Animation via timer callback and global offset variable
