How 2D first person rpg dungeons are rendered(Wizardry, Strange Journey, Bard's Tale...)?

[Viata]

What I mean is this:

In all those games I can see two to four steps ahead. How this works?
I know that it's a 2D grid for the maze, there's a variable for what direction my character is facing and then the walls are rendered based on what direction my char is facing. But I'm wondering about the steps ahead from where my char is standing. Is this rendered as a single image:

Or are various images like this:

?

In most cases I think it was the second option (multiple wall tiles making the scene).
This thread talks briefly about how these tilesets are constructed visually (see the 4th post) :

And this PDF document is someone's in-depth analysis of how Eye of The Beholder worked on a programming level:

At one point I found the actual tileset images Eye of the Beholder used but can't find it at the moment. I'll look around for that.

I have considered using such a system for my own dungeon crawler, but lately I'm thinking I might just go with true 3D which is much simpler to deal with. There is certainly a visual charm to the 2D method though.

I read the two links and thanks, Alchemist. The first one explained my doubt pretty well and the pdf document helped me understand better how the programming works in the game.

Cool - glad to hear it was helpful. I've been looking into this stuff for a while and I'm happy to share what I found.
