Raycaster-OpenGL

A Raycaster written with C++ and OpenGL using Visual Studio.

What is a raycaster?

Raycasting is used to efficiently render a 3D world from a 2D playing field using a simple one-dimensional scan over the horizontal width of the screen. Early first-person shooters used 2D ray casting as a technique to create a 3D effect from a 2D world. While the world appears 3D, the player cannot look up or down or only in limited angles with shearing distortion. Read more here.
