2D Drawing Program in C++

A Windows desktop application written in C++ for interactive 2D drawing and graphics algorithm visualization.

Features

• Customizable UI:

  • White or Dark background window
  • Custom mouse cursor shape
  • Mouse-only interaction (no keyboard input)
  • Dropdown menus for options and commands

• Drawing:

  • Select shape color before drawing from menu
  • Draw points, lines, circles, ellipses, polygons, and curves

• Algorithms Implemented:

  • Line Drawing:
    • DDA (Digital Differential Analyzer)
    • Midpoint line algorithm
    • Parametric line algorithm
  • Circle Drawing:
    • Direct method
    • Polar coordinates method
    • Iterative polar method
    • Midpoint circle algorithm
    • Modified midpoint circle algorithm
  • Ellipse Drawing:
    • Direct
    • Polar
    • Midpoint
  • Curve Drawing:
    • Hermite curves
    • Bezier curves
    • Cardinal spline curves
  • Filling Algorithms:
    • Circle filling with lines and smaller circles (with user-selected quarter)
    • Filling square using Hermite curve (Vertical)
    • Filling rectangle using Bezier curve (Horizontal)
    • Convex and Non-Convex polygon filling
    • Recursive and Non-recursive flood fill algorithms
  • Clipping Algorithms:
    • Rectangle clipping window for points, lines, polygons
    • Square clipping window for points and lines

• Additional Functionalities:

  • Clear screen option to erase all shapes
  • Save current drawing data to file
  • Load drawing data from file

How to Build

1. Requirements:

   • Windows OS
   • C++ compiler supporting Windows API (e.g., MSVC / Visual Studio)

2. Steps:

# Clone repo
git clone https://github.com/alaaashraf19/2D-Drawing-Program.git
cd 2D-Drawing-Program

# Build using your method (Visual Studio project - Windows Desktop Application C++ / CMake etc.)
# For example, open the `.sln` file in Visual Studio and build
