Being a fan of early “3D” shooters such as Doom and Blood, I thought I would attempt to create a raycasting engine for one of my university projects in JavaScript using the P5 library. I mainly studied raycasting by reading the Wolfenstein 3D Black Book and purchasing a course on Pikuma.com. This project was exciting to work on and allowed me to brush up on basic mathematics, as raycasting engines require trigonometry when calculating the direction of each ray.
