Tip

Live Implementation: For a comprehensive visual showcase, visit the CG Lab Portfolio Dashboard. For the complete source code and detailed documentation, visit the Computer Graphics Lab directory. Visualization is key. Always sketch your graphics output on paper before coding. Draw coordinate systems, trace pixel positions for line/circle algorithms step-by-step, and visualize transformation matrices with example points. Understanding the mathematical foundation - Bresenham's error terms, midpoint decisions, and symmetry properties - is essential for implementing efficient graphics algorithms.

Warning

Environment Setup: These programs require Turbo C++ or a compatible environment with the graphics.h library. Modern compilers like GCC/Clang do not support graphics.h natively. Use DOSBox with Turbo C++ or WinBGIm library for modern systems.

How to Use

These programs require Turbo C++ or a compatible environment with the graphics.h library.

Using Turbo C++

1. Open Turbo C++ IDE
2. Load the .c file
3. Compile using: Alt + F9
4. Run using: Ctrl + F9

Using DOSBox with Turbo C++

1. Install DOSBox on your system
2. Mount your Turbo C directory
3. Navigate to the file location
4. Compile and run as above

Example:

mount c c:\tc
c:
cd bgi
tc
