Procedural City: Room Decorations

It's time to add more decorations to the rooms in my procedural buildings. The walls and floors look too plain, so that's a good place to start. First up is office buildings. I added hardwood floor textures to houses, but office buildings are still using simple gray floors. I downloaded five office carpet textures and added them to the pool of randomly selected floor textures for non-house buildings. Here is an example.

Next up are houses. The hardwood floor textures look good, but I need to add some variety. How about fancy rugs covering some of the floors? I found five rug textures online, and added support for selecting random rugs and placing them in some rooms. Rooms that are otherwise empty (no table or chairs) have a higher chance of getting a rug so that they're not totally empty. These rugs are randomly sized and positioned randomly somewhere near the center of the room.

That's good for floors, so it's time to work on the walls. The most obvious decorations to add to walls are framed pictures, and what better pictures to use than my library of 3DWorld screenshots. I added ten full resolution 1920x1024 screenshots of various scenes including nature, reflections, a procedural universe, and buildings. I even threw in one of my skybox images, which wasn't created by me. (Note that these images are large and haven't been added to the 3DWorld GitHub project.) Here is a room with a nebula picture on one wall and a reflective Sponza Atrium picture on the the other wall.

But wait! Why limit pictures to existing images? Why not allow the player to create their own photos for hanging up on the walls? Sure, let's do that, just for fun. I added a hotkey to take a screenshot and add it to the building photo library, which replaces the initial screenshot images. Now the user can populate rooms with their own selected artwork.

In fact, you can take screenshots of these pictures and create new pictures. The nesting of screenshots is unlimited.

Here's another example.

A screenshot I took of the nearby city placed as a picture on the wall.

That's good for houses, but office buildings don't have many pictures on their interior walls. What they do have are offices, and many offices have whiteboards. I can conveniently reuse the picture system with a blank white texture and an added ledge to form a whiteboard.

That's good enough for now. This was actually a pretty easy task, at least compared to some of the other work I've done on buildings such as navigation for people. At this point it's unclear what I should add next. I suppose more room furniture and smaller details is always useful.
