I have example shaders here showing the sim city technique, with some extra comments explaining what each line is doing.

Interior Mapping

[2751518--198474--interiormapping-cubemap.jpg] Emil Persson’s Cube Map based interior mapping [2751518--198479--interiormapping-2dAtlas.jpg] Andrew Willmott’s SimCity 5 style texture atlas interior mapping Both of these could be made better in several ways, especially with better art.
