This project is an intelligent marketing interactive system for smart‑city solutions based on 3D digital twin technology. Its dual‑engine architecture builds a 1:1 3D replica of a city or campus and offers a visualization portal for enterprise demos. Preconfigured modules cover transportation, energy, manufacturing lines, and offices. Dynamic slicing and physics‑based modeling present complex workflows and real‑time emergency drills. Data interfaces enable live‑data import for simulation, and one‑on‑one customization meets industry needs.
