Dragon Curve Fractal – COMP3710 Demo 1 (Task 3)

This repository contains my implementation of the Dragon Curve fractal using Python and Matplotlib for COMP3710.

The dragon curve is generated using an L-system with rules:

• F → F+G
• G → F–G

It demonstrates self-similarity and has a fractal dimension ≈ 2, meaning it is almost space-filling.

#Features

• L-system implementation (dragon_curve_sequence and draw_dragon_curve)
• Multiple visualisations:
  • Default blue line
  • Coloured progression using viridis colormap
  • Red version
  • Dashed green line

#AI PROMPT LOG

Prompt 1: "Help me write the Python code to generate and plot a dragon curve fractal using an L-system."

AI Output (excerpt): Provided basic sequence function (F → F+G, G → F–G) and a turtle-style drawing function.

What I learned:

-The dragon curve is created by rewriting rules (L-system).

-Each “+” and “–” corresponds to a 90° turn, which generates the folding pattern.

Prompt 2: "Why is my dragon curve showing up as only a flat line?"

AI Output (excerpt): Explained that I needed to update the angle when encountering “+” and “–”, and to use plt.axis("equal") to avoid distortion.

What I learned:

Importance of updating the angle correctly when turning.

Using equal axis scaling so the curve is not squashed into a line.
