## Overview

This is a GLUT/OpenGL animated city-scene program. Its user-facing flow is a window displaying a city, with mouse input and timer-driven animation; the scene includes buildings, roads, weather, and moving vehicles including a train. The source is a single monolithic file, so the graph groups responsibilities within that file rather than implying separate modules. The README is empty and the source excerpt is partial, so audio-file usage and some callback wiring are not established.
