Raycasting Renderer in C

Cub3D is a 3D visualization project built using raycasting.
It renders a 3D environment from a 2D map, inspired by Wolfenstein 3D.

Overview

This project was developed as part of the 42 curriculum, focusing on low-level graphics and how 3D like scenes can be simulated without a real 3D engine.

It demonstrates how perspective, depth, and walls can be rendered using only mathematical calculations and a 2D grid.

Features

• Player movement (WASD)
• Camera rotation (left/right)
• Wall rendering using raycasting
• Map parsing from .cub files
• Collision detection
• Distance-based wall scaling
• Texture mapping and rendering

Built With

• C
• MiniLibX
• trigonometry

Usage

git clone https://github.com/yourusername/cub3d.git
cd cub3d
make
./cub3D maps/map.cub

What I Learned

• How raycasting works in practice
• Translating math into visual output
• Handling rendering loops and performance in C
• Managing memory and structures in a graphics context

Notes

This project is a simplified renderer and not a full 3D engine.
Its purpose is to understand the fundamentals of rendering and perspective.
