Plan → 3D cityscape: City visualization powered by Nano Banana
What it does
Turn complex 2D plans into intuitive 3D models. Nano Banana reads footprints, roads, and green areas, then extrudes buildings and preserves road curvature/widths for a consistent, informative cityscape.
How it works
- Upload a labeled floor plan or master plan.
- Describe desired heights, view, and rendering style.
- Generate and iterate; export.
Prompt example
Generate an orthographic isometric cityscape based on the provided floor plan. Extrude building footprints to their labeled heights and floors. Preserve road curvature and lane widths precisely. Loft bridges over the river as indicated. Render in a clean, minimalist clay render style with global illumination and overcast HDRI lighting.
Output example
Why it matters
- Present plans visually in minutes instead of days of manual 3D work.
- Demonstrates strong spatial reasoning — deriving 3D from 2D reliably.
- Lower technical barriers so more teams can communicate ideas clearly.
