2D Raytracing Engine in C++ & SFML

A 2D Raytracing engine developed in C++ using the SFML graphics library. This project was created for educational purposes to explore rendering concepts, computational geometry, and light simulation.

About the Project

This project implements a real-time ray casting/tracing system. The goal is to simulate the interaction of "light" or field of view with geometric obstacles in a 2D environment. Main objective: understand more about ray casting and computer graphics while enhancing C++ skills.

The architecture separates the core physics logic (raytracing) from the drawing logic (renderer), ensuring modular and maintainable code.

Technologies

• Language: C++
• Graphics Library: SFML (Simple and Fast Multimedia Library)
• Build System: GNU Make

How to Build and Run

Prerequisites

Before compiling, ensure you have g++, Make, and the SFML library installed. Link for SFML instalation guide here

Linux Dependencies

• Debian / Ubuntu / Pop!_OS:

  sudo apt-get install libsfml-dev g++ make

• Arch Linux:

  sudo pacman -S sfml base-devel

• Fedora:

  sudo dnf install SFML-devel gcc-c++ make

Compiling

This project uses a Makefile for easy compilation. Open your terminal in the project folder and run:

make
