RayCasting 3D Simulation

A C++ project that utilizes raycasting to simulate a 3D-style environment from a 2D image, inspired by retro games like Wolfenstein 3D, utilizing the SFML library to handle graphics and input.

Introduction

Inspired by videos I watched on the math behind raycasting, I decided to try and implement the system myself from scratch using C++. I also decided to do this project to help develop my skills in CMake, GTest, and modern C++17 techniques. The math behind raycasting can be found here: https://www.youtube.com/watch?v=NbSee-XM7WA

Features

• Converts image to 2d map to be rendered in 3d
• First-person player controller using WASD keys and mouse
• Hue Shifting Algorithm implemented using a simulation of a color cube rotation
• RayCasting simulation using physics, made more efficient by a grid-based system
• Player collision detection
• 3D-style environment with a simple shader system
• SFML integration
• Custom Vector template class

Dependencies

• C++17 or later.
• CMake version 3.16 or later
• SFML 2.6
• ImGui v1.89

Controls

WASD to for directional movement. Mouse movement rotates player character horizontally and vertically. Press ESC to free mouse from window.

Improvements

I hope to add more player movement options such as jumping in the future to help immerse the player in the world, as well as adding support for textured terrain and a more advanced lighting system. Prior to these features, I want to ensure that the code is as clean as possible, and manage the amount of required dependencies
