The name of this 3D rendering engine I made is called 3D Ice-Cream-Sandwich. It works in a similar way that doom worked. It works by taking layers and fanning them out kind of like a deck of cards. I call it Ice-Cream-Sandwich because the different layers are kind of like a sandwich and I like ice cream! This could definitely be used for a Crossy Road style game!
I am more than likely not the first person to make an engine that works like this.
