It's quiet here so perhaps I can help with some images of my real-time model.
I built this model of the WTC complex for the game Counter Strike Source (CS:S) back in 2005.
I spent a month making textures and another month building the map.
There was only photo's on the net to work with back then so it's not perfect but a reasonable likeness.
CS:S was updated so I re-compiled the map to work with the new version (2011).
Being a 3D game engine you can walk and even fly around the map. You don't have to play the game
you can just spectate. Just keep in mind that it's all smoke and mirrors. Only the north tower has internal details.
You can fly to areas on the level that wouldn't be accessed while playing the game and there are holes.
Here's some more images
Or you can download the map for free from
GameBanana
You will need the CS:S game but that can be downloaded for $20 these days.
