📝 About The Project

I alway had the dream of combining math and programming in hopes of creating cool stuff with them, so after spending a bit of time searching I got advised to enter the world of graphics programming. this was my first choice as a project for this topic.

☁️ Overview

This project is a simple implementation of a raycasting engine which will render a pseudo 3D world using 2D linear algebra calculations in order to cast rays and render the world based on them. Basically the further the ray is stopped and has hit a wall, smaller the height of the wall will be which is a stripe with length of one pixel.

💾 Project Files Description

Headers and source files are separated into to different directories, include and src. Source files are all in src and defined headers are in include.

• Globals.hpp - Where all Global settings are stored.
• MyFuncs.hpp - Where commonly used functions are declared.
• Game.hpp - Where all configuration of the application window and events are done.
• Map.hpp - Where map and its logics are set up.
• MyTriangle.hpp - This is a Draw able sprite for the map.
• Player.hpp - Configuration for camera which is the player's eye.

📖 Getting Started

At first clone the repository:

$ git clone https://github.com/Sephixum/SFML_Raycast.git

As an exmaple you can first generate a build directory for cmake:

$ cmake -S . -B build

Build and compile:

$ cmake --build build

You can run the project:

$ ./build/raycasting

Usage

You can move around the map using W A S D.

Camera can be rotated with keys H (anticlockwise) and L (clockwise).

Arrow key Down and Up can be used to increase of decrease vision density.

You can reset your vision density with R.

I have been studying concepts from Lode's Ray Casting Tutorial so here is the link for it.
