I am building a website which allows visitors to peruse an interactive map of a group of buildings. Each building is divided into floors and rooms. I have been given a 3D map of the entire group of buildings (the "site"), but only 2D floorplan views of the individual buildings themselves. Each building has several identical floors. The client states that he can't get 3D views of each building from the architect, so the drawings I have are all that can be provided.
I have already created an image map overlaid onto the 3D site view, allowing the user to choose the desired building. Now, I'm looking for ideas on how to best present a multi-floor building to the user, allowing the user to see how many floors there are, choose a floor, then choose a room within that floor.
Thanks for any ideas.
