{ We have an official [LRS](lrs.md) library for advanced 2D raycasting: [raycastlib](raycastlib.md)! And also a game built on top of it: [Anarch](anarch.md). ~drummyfish }
{ Also there is a very cool oldschool book that goes through programming a whole raycasting game engine in C, called *Tricks of The Game Programming Gurus*, check it out! ~drummyfish }
2D raycasting can be used to relatively easily render "3Dish" looking environments (commonly labeled "[pseudo 3D](pseudo3D.md)"), mostly some kind of right-angled labyrinth. There are limitations such as the inability for the camera to tilt up and down (which can nevertheless be faked with shearing). It used to be popular in very old games but can still be used nowadays for "retro" looking games, games for very weak hardware (e.g. [embedded](embedded.md)), in [demos](demoscene.md) etc. It is pretty cool, very [suckless](suckless.md) rendering method.
