Instead, it divides the scene into independent columns and renders them one-by-one. Each column represents a single ray cast out from the player at a particular angle. If the ray hits a wall, it measures the distance to that wall and draws a rectangle in its column. citing government documents chicago

That is, for raycasting, we cast 1 ray per 1D vertical stripe and do 2D intersection math with objects. In raytracing, instead you cast 1 ray per pixel of the entire 2D screen, and do 3D intersection math with objects.
