znatri / basic-rasterization-graphics

A basic rasterization graphics pipeline implemented from scratch, demonstrating fundamental concepts such as triangle rasterization, line drawing, and transformations.

Basic Rasterization Graphics Project

This project is a simple implementation of rasterization in computer graphics, which involves converting geometric primitives such as points, lines, and polygons into a raster format suitable for rendering on a display. The project is designed for educational purposes, helping students understand the fundamentals of rasterization and its role in computer graphics.

Project Overview

The main goal of this project is to practice the basic principles of rasterization, including:

• Drawing points and lines using Bresenham's line algorithm
• Filling polygons using scanline algorithm
• Implementing transformations, such as translation, scaling, and rotation
• Clipping lines and polygons using Cohen-Sutherland and Sutherland-Hodgman algorithms

The project is developed using C++ and OpenGL, and it provides a simple user interface to interact with the implemented features.

Getting Started

Prerequisites

• C++ compiler with C++11 support
• OpenGL and GLUT libraries

Compiling and Running the Project

1. Clone the repository:

git clone https://github.com/znatri/cs3451_p1_rasterization.git

2. Navigate to the project directory:

cd cs3451_p1_rasterization

3. Compile the project:

make

4. Run the compiled executable:

./rasterization

Usage

The user interface allows you to interact with the implemented features through keyboard shortcuts:

• P: Draw points
• L: Draw lines
• F: Fill polygons
• T: Apply translation
• S: Apply scaling
• R: Apply rotation
• C: Clip lines and polygons
