Yeah, everything in Wolf 3D is flat - no height variations. Moreover, all angles are right angles (90 degrees), which means all shapes are squares and rectangles. One of Doom's original advertising points was its non-orthogonal walls, which was a great step ahead.

So basically, making maps in Wolf 3D is a process of filling squares on a pre-defined grid. Each square is either a wall, an object or empty space. Here is an example.

Oooh, can I see a screenshot of your room with four pillars? Maybe you can sell it under the name "Q4 - a whole new dimension (now with pillars!)" :P
