3D WebGIS Urban Flood Analysis MVP

Minimal validation prototype based on the thesis proposal: 3D city scene, dynamic flood playback, rainfall particles, depth query, affected building extraction, and browser-side performance indicators.

Scenario Controls

Current stage: Initial rainfall
Click a building to query local depth and flood impact.
MVP simplification: Cesium/Three dual-engine integration is represented here through a modular 3D scene architecture and geospatial-style analysis workflow, enabling rapid validation of the thesis concept before full Cesium integration.

Platform Metrics

Flood depth 0.20 m
Affected buildings 2
Inundation area 1,120 m²
FPS 60
Metrics update in real time with flood stage changes to validate analytical interaction.
