CSE423 - Computer Graphics

This repository contains academic resources, lab work, and materials for the Computer Graphics (CSE423) course.

Course Overview

Computer Graphics is a comprehensive course covering the fundamental concepts and practical implementations of graphics programming, including:

• Introduction: Overview of graphics systems, applications, and display technologies
• Line Drawing: DDA and Mid Point line drawing algorithms
• Clipping: Cohen-Sutherland and Cyrus beck clipping algorithms
• Transformation: 2D and 3D transformations (translation, rotation, scaling, etc)
• Projection: Parallel and perspective projections, viewing transformations
• Color Model: RGB, CMY, HSV color spaces
• Lighting Model: Ambient, diffuse, and specular lighting, Phong reflection model
• Curves: Continuity, Bezier curves, and parametric representations

Lab Assignments

This repository contains Computer Graphics lab assignments implemented in Python using PyOpenGL and GLUT.

Lab 1: 2D Primitives & Animation

Focus: Basic OpenGL primitives (GL_POINTS, GL_LINES, GL_TRIANGLES), interaction, and animation.

• Task 1 (House in Rainfall): A 2D scene featuring animated rain with wind direction control (arrow keys) and a day/night background transition.

• Task 2 (The Amazing Box): An interactive simulation of bouncing points featuring mouse-click spawning, speed adjustments, and blink effects.

Lab 2: Midpoint Line Drawing Algorithm

Focus: Scan conversion algorithms and 8-way symmetry.

• Project (Catch the Diamonds): A falling-object game rendered entirely using the Midpoint Line Drawing Algorithm (generating lines using only GL_POINTS).

• Features: Custom implementation of lines for all 8 zones, AABB collision detection, and interactive UI buttons (Pause, Resume, Restart).

Lab 3: 3D Transformations & Projections

Focus: 3D Coordinate systems, Geometric Transformations, and Camera Control.

• Project (Bullet Frenzy): A 3D shooter game utilizing gluPerspective and gluLookAt for scene rendering.

• Features:
  • 3D Modeling: Hierarchical character models (Player, Enemies) built using cylinders and spheres.
  • Camera: Toggleable First-Person and Third-Person perspective modes.
  • Mechanics: Enemy pursuit AI, 3D collision detection, and an auto-aim "Cheat Mode".
