Computer Graphics 2D Basics with GLUT

This repository contains a simple C program demonstrating 2D graphics using the OpenGL Utility Toolkit (GLUT). The program creates a window and draws a square that can be manipulated using keyboard input. The primary features include:

• Square Manipulation: Use keyboard inputs ('w', 'a', 's', 'd', arrow keys) to move and scale a green square on the screen.
• Visual Feedback: A label at the top of the window displays information about the last pressed key and its corresponding action.
• Rotation Animation: The square rotates continuously, adding a dynamic visual element to the graphics.

Features

• Square Drawing: Utilizes OpenGL to draw a simple green square on a black background.
• Circle Drawing: Implements a function to draw a green circle with specified radius and segments.
• Axes Drawing: Renders red (x-axis) and blue (y-axis) lines to represent coordinate axes.
• Keyboard Interaction: Responds to both regular and special (arrow keys) keyboard inputs for square movement and scaling.
• Label Display: Shows a label indicating the last pressed key and its associated action.
• Rotation Animation: Implements a timer function for continuous rotation of the square.

Usage

1. Clone the repository to your local machine.

   git clone https://github.com/your-username/computer-graphics-2d-basics-glut.git

2. Open the project in an OpenGL/GLUT compatible development environment, such as Visual Studio.

3. Build and run the project to see the 2D graphics window with interactive square manipulation.

Note: Make sure to have the necessary GLUT and OpenGL dependencies installed to run the program successfully.
