This is a 3D bedroom that I made within Maya. I used textures from a free texture website.

 

I started off with an outline for a floor plan that I found off of google. I then created the walls for the actual room, along with the floor and ceiling.

The next step was to create the door, which I had to etch out of the wall and then combine it with the wall on a hinge so that it could open just like a real door. 

 

After that, I created the windows, using the same method as the door, but I didn't connect them to make them open. Following this I created all of the furniture in the room, starting with the dresser and bed, and then moving onto the TV and what would be a Game Area if it were my room. 
 

Finally, I textured everything and smoothed the things that should be smoothed, like the mattress and pillows, and then added lighting and shading to the room for various different time of day effects. This took a lot of time to create, and I am very happy with my creation of the room.
