Spiraldiagramm-Simulator (Spiral Generation Simulator)

• Desktop-App zum Simulieren der Generierung mehrerer mathematischer Spiraldiagramme. (Desktop app for simulating generation of several mathematical spirals.)
• Die App besteht aus einer grafischen Benutzeroberfläche und ist vollständig in der C-Programmiersprache geschrieben. (This app has graphical user interface and is written fully in C-language.)

• I wrote this desktop application completely in C-language using the GTK4 library for the user interface and Cairo for 2D graphics rendering.
• The app allows users to select and visualize various mathematical spirals, simulating their construction point-by-point.
• spiral_generator.h: Header file defining constants, enums, structs, and function prototypes.
  • Constants: WINDOW_WIDTH (800), WINDOW_HEIGHT (600), ANIMATION_STEPS (1000), ANIMATION_INTERVAL (20 ms).
  • Enum SpiralType lists all supported spiral types.
  • Struct SpiralData stores x and y coordinates, max_points, and current_point for simulation.
  • Struct AppData combines SpiralType, drawing_area, two SpiralData instances (primary and secondary), and animation_id.
• main.c: Entry point, initializes the GTK application, and sets the default spiral.
• gui.c: Handles GUI setup, spiral selection, and simulation logic.
• Spiral-specific files (e.g., theodorus.c, archimedean.c, etc.): Each implements drawing logic for a specific spiral.
• I have used GTK4’s GtkApplication, GtkWindow, GtkBox, GtkDrawingArea, and GtkListBox for interface components.
• Cairo draws spirals on the GtkDrawingArea using cairo_t contexts.
