🎨 Computer Graphics Project - C++ & OpenGL

This project implements various computer graphics algorithms using C++ and OpenGL. The focus is on fundamental rendering techniques, line drawing, ball bouncing projection, and ray tracing.

🚀 Implemented Algorithms

📏 Bresenham's Line Drawing Algorithm

Bresenham's algorithm is an efficient way to draw lines on a raster display. It uses integer calculations to determine the closest pixel for a smooth and accurate line without floating-point operations.

✂️ Cyrus-Beck Line Clipping Algorithm

A parametric line-clipping algorithm used in computer graphics for convex polygon clipping. It determines the visible portion of a line segment that lies inside a convex polygonal region.

🔭 Projection

Projection transforms 3D objects onto a 2D screen. This project implements:

• Orthographic Projection: Preserves parallel lines without perspective distortion.
• Perspective Projection: Mimics the way the human eye perceives depth.

🔄 Projection with Rotation

Extends the projection technique by adding rotational transformations, allowing objects to be viewed from different angles before projecting them onto a 2D plane.

🏞️ Slope-Independent Line Drawing

Unlike traditional algorithms, this technique avoids division operations, making it efficient for real-time applications where precision and speed are crucial.

✈️ Visible Plane Detection

Determines which parts of a 3D object should be visible in a scene, helping to remove hidden surfaces and improve rendering performance.

🖼️ Bitmap Image Rendering

Uses bitmap images as textures in OpenGL to display graphical elements with pixel-perfect accuracy.

☀️ Ray Tracing

A powerful rendering technique that simulates realistic lighting by tracing rays from the camera to light sources. It accounts for:

• Reflection
• Refraction
• Shadows
• Light absorption

🏀 Ball Bouncing Simulation

This simulation demonstrates realistic bouncing ball physics using OpenGL. The ball follows a natural bouncing motion with gravity applied. The motion includes:

• Gravity-affected movement
• Collision detection with the ground
• Shape deformation upon impact
• Dynamic motion adjustments

🛠️ Tech Stack

• C++ ⚡
• OpenGL 🎨
• GLUT (OpenGL Utility Toolkit)
