Raytracing Engine

This is a simple raytracing project written in C++. It renders images based on user input for image width and samples per pixel. The rendered image is saved in output.ppm.

Getting Started

Prerequisites

• C++ compiler (supporting C++11)
• Git

Compilation

Clone the repository:

git clone https://github.com/Kaamyab/Ray-Tracing-Engine.git
cd Ray-Tracing-Engine

g++ main.cpp -o main -std=c++17

Running the Program

Run the compiled program:

./main

Follow the prompts to enter the image width and samples per pixel.

How Raytracing Works

Raytracing is a technique used in computer graphics to simulate the way light interacts with objects in a scene. The basic steps involve shooting rays from the camera into the scene, calculating the intersections with objects, and determining the color of the intersected points.

In this project:

• The user provides the image width and samples per pixel.
• The program shoots rays through each pixel, adjusting for the aspect ratio.
• For each pixel, multiple rays are traced (samples per pixel).
• The program calculates the color of each pixel by simulating the interaction of light with objects in the scene.
