Jeff Rient's post yesterday about 3D dungeons got me to thinking. Actually, I 've been thinking about the same thing for a while, so I should say that his post got me to doing. I played around a bit with doing side views skewed to represent the 3rd dimension so as to show dungeon levels that do not neatly stack on top of each other.
This is a rough pass:
No, your eyes are not blurring. The image is blurred a bit on purpose. But I think that you can make out the idea.
It needs a lot of work yet, but I like it. The one big hitch I have hit with it, ironically, is depicting levels that do stack neatly on top of each other. They are kind of hard to make out. But, I'm still playing with it.
