A raycasting engine built in C with MiniLibX
Get Started Technical Docs

cub3D

Section titled “cub3D”

cub3D is a raycasting project in C with MiniLibX. This guide follows the repository as it exists today, covering both the mandatory engine (parsing, validation, input, and rendering) and the bonus systems (minimap, doors, sprites, pickups, HUD, retro rendering, and level progression).

Engine Preview

Section titled “Engine Preview”

Visual Reference Rebuilt for Starlight

This page includes an interactive illustration of the core view: a 2D map, a 3D player view, and live controls for heading and position.

It is a preview, not the game itself. It reflects the main raycasting ideas used in cub3D: player state, a field-of-view wedge on the map, and screen columns derived from DDA wall hits with fisheye correction.
