42 Cub3D 🧊

Cub3D is a Wolfenstein/Doom 3D-inspired raycasting project developed entirely in C as part of the 42 curriculum. It provides a basic 3D rendering engine using raycasting

Features

• Raycasting Engine: Implements a first-person perspective using raycasting.
• Textured Walls & Floor Casting: Supports wall textures and basic floor and ceiling rendering.
• Player Movement: Includes rotation and movement with collision detection.
• Configurable Map Parsing: Reads .cub files defining walls, textures, and player spawn.
