Computer Graphics (Python) — Course Assignments

Overview

This repository contains 7 assignments developed during the Computer Graphics course.
Each assignment demonstrates concepts such as coordinate transformations, interpolation, rasterization, and simple game development using Python.

Assignments

Tema 1 — Coordinate transformations

• Convert coordinates between Cartesian and polar (and vice versa).
• Rotate point A(2,4) around origin O(0,0) by 30°.
• Apply symmetry of point A(-3,-2) with respect to center M(5,5).
• File: tema1.py

---

Tema 2 — Aitken’s Algorithm

• Implementation of Aitken’s Δ² method.
• File: tema2.py

---

Tema 3 — Orthogonal axes and lines

• Generate OXY axes and draw:
  • one vertical line
  • one horizontal line
  • one oblique line
• Each line has a different color.
• File: tema3.py

---

Tema 4 — 3D Transformation

• Implementation of one 3D geometric transformation studied in class.
• File: tema4.py

---

Tema 5 — Bresenham Rasterization Algorithm

• Implementation of Bresenham’s line rasterization.
• File: tema5.py

---

Tema 6 — Pygame Scene

• Static objects: 2 snowmen.
• Animated objects: rotating snowflake, moving airplane.
• File: tema6.py

---

Tema 7 — Space Invaders (Pygame)

• Features:
  • Player moves left (A) / right (D) and shoots (Space).
  • Destructible bunkers.
  • Enemies arranged in 5 rows.
  • Closest enemy in each column attacks.
  • Score & High-Score (saved between runs).
• Files:
  • tema7.py
  • score.txt
  • highscore.txt

---

How to Run

1. Install dependencies:

   pip install pygame numpy matplotlib

2. Run a script, e.g.: python tema1.py

python tema7.py

Notes

These assignments showcase fundamental concepts in 2D/3D graphics, algorithms, and game development with Python.

Files score.txt and highscore.txt are used by the Space Invaders project to save results between runs.
