Raycasting Engine with Light Simulation

raycasting.mp4

Overview

This project is a simple 2.5D raycasting engine built in Processing (Java). It was inspired by classic games I played like Wolfenstein 3D and Doom. The program renders a first-person view of a grid-based map using raycasting techniques, along with a bit of math and physics. It includes dynamic lighting, file-based maps, and a GUI for real-time control of parameters. It was a grade 12 CS project completed in 2026. The goal was to learn core raycasting techniques and methods, as well as the physics and math formulas behind them.
