用Blender重建1893年芝加哥世博会场景

Build a 3D reconstruction of a historic world's fair in Blender, driven by a Python script. First gather historical photographs, maps and building dimensions, and note where sources disagree. Model each major hall as a simple white-plaster block with its dome, columns and portals, plus a lagoon, a basin, tree-lined paths, a railway with a steam locomotive and a terminal station, all placed according to an old fairground map. Use a pale palette of white buildings, green lawns and blue water under a clear sky. Render a side-by-side sheet for each building comparing the original photo with your model, then an aerial view of the whole grounds. Let the user walk or fly around the scene to feel its scale. Start with a rough minimum viable version of the layout, then refine facades one building at a time, checking each against its reference photo. Done means a navigable scene whose main buildings match the historical layout and proportions.
