3D - 2

What program allows you to walk around in your 3D models?

When I say "Walk", I mean to literally walk in a first person viewpoint around my models. I want a program that allows me to walk in my models with the WASD keys and use my mouse to look around, like a First Person Shooter game. I made a couple of 3D models of my house's interior, and I want to walk around it, as If in a First Person Shooter game. Can anyone tell me a couple programs that allow me to do this?

1. I heard in the game quake you can create your own worlds, and characters, and load them in the game.
2. Google Earth might be a good one to start with
