Want to turn a standard weather report into a work of art?
You might find online that many people crafted a specific AI prompt that transforms any city—like Beijing—into a charming, 45-degree isometric miniature world.
This technique renders iconic landmarks as cute 3D cartoon scenes with soft, realistic textures, while seamlessly integrating current weather icons, dates, and temperatures. It’s the perfect way to create “micro-world” aesthetics that look like high-end digital toys.
Tool: Gemini AI – Nano Banana Pro
3D miniature city of Beijing
At the beginning, we used the following prompt to try generating a 3D miniature city of Beijing (北京). You can change the “XXX” into the city you want to experiment.
City= XXXX
Present a clear, 45* top-down isometric miniature 3D cartoon scene of (City), featuring its most iconic landmarks and architectural elements. Use soft, refined textures with realistic PBR materials and gentle, lifelike lighting and shadows. Integrate the current weather conditions directly into the city environment to create an immersive atmospheric mood. Use a clean, minimalistic composition with a soft, solid-colored background. Then we have the following output:
Based on this 3D miniature, we would like to have the city name (“Beijing” here) and also have the weather details on the date we tried it on Gemini Ai.
So the full prompt was changed to:
City= XXXX
Present a clear, 45* top-down isometric miniature 3D cartoon scene of (City), featuring its most iconic landmarks and architectural elements. Use soft, refined textures with realistic PBR materials and gentle, lifelike lighting and shadows. Integrate the current weather conditions directly into the city environment to create an immersive atmospheric mood. Use a clean, minimalistic composition with a soft, solid-colored background.
At the top-center, place the title (City) in large bold text, a prominent weather icon beneath it, then the date (small text) and temperature (medium text). All text must be centered with consistent spacing, and may subtly overlap the tops of the buildings.
Image Ratio is 1:1Then we have the output image as follow (it was snowing in Beijing on December 15th, 2025):
3D miniature city of Hong Kong/Los Angeles
Then we tried another city of Hong Kong by changing the city name only (to “香港”, you can also try to input English one like Los Angeles).
The result of Hong Kong, as who lived in the city before feels, is not bad, and demonstrated several landmark buildings of the financial hub.
However, when I changed it to Los Angeles, and removed the image ratio. There would be minor bug: the Observatory was repeated in the image.
Present a clear, 45° top-down isometric miniature 3D cartoon scene of [City], featuring its most iconic landmarks and architectural elements. Use soft, refined textures with realistic PBR materials and gentle, lifelike lighting and shadows. Integrate the current weather conditions directly into the city environment to create an immersive atmospheric mood. Use a clean, minimalistic composition with a soft, solid-colored background. At the top-center, place the title "[CITY]" in large bold text, a prominent weather icon beneath it, then the date (small text) and temperature (medium text).
CITY == Los Angeles
You can copy the prompt and try for other cities. Cheers.
