matrix.hpp	Fenscaster is now using the first version of Lode's DDA raycasting algorithm but the coordinates/angles in the left map view don't matchthe right view, and the right view distorts the distance to far wall so they're viewed at 'infinity'.	1 year ago

Simple Raycaster Study

This is a study project for me to learn the raycasting technique. It's an older technique that's not really used much but I'm learning game dev historically and it's definitely been used in the past (Doom).

I've been told to look into the following as well:
