As a big fan of procedural generation, I feel like I don’t see enough procgen of indoor environments or building interiors. Sure, you’ll see dungeon generators just about everywhere, and plenty of terrain or landscape generation. Even city generation is fairly common, but I struggle to find examples of people procedurally generating building interiors.
Even when people do procedurally generate interiors, they don’t exactly feel natural. There’s something that separates a building layout designed by an architect or engineer from that of a procedural system.
I think I’m going to play around with some different techniques and see if I can figure out a good system.
