MiniRT: A Journey into Ray Tracing and Computer Graphics

Project Overview

MiniRT represents a sophisticated exploration of computer graphics through the implementation of a ray tracing rendering engine. Developed using the C programming language and miniLibX graphics library, this project provides a comprehensive introduction to the fundamental principles of 3D image generation.

Technical Foundation

Ray Tracing Methodology

Ray tracing is an advanced rendering technique that simulates the physical behavior of light, producing highly realistic computer-generated images. Unlike traditional rasterization methods, ray tracing traces the path of light rays as they interact with objects in a virtual scene, capturing complex visual phenomena such as reflections, shadows, and light interactions.
