城市天际线3D地图立体模型

提示词 Prompt

I first tried this prompt on Nano Banana. It looks so much better with GPT Image 2. 2 images, do this for Mecca and Shanghai, 1080x1080, Do this for Paris: <instruction> 1. The Semantic Inference Engine (Cartographic Typography): Input A is a Major City Name (e.g., Shanghai, London, Dubai). Analyze the location to generate 3 Integrated Assets: The Monoliths (The Abbreviation): Extract the letters of Input A. These will be the primary vertical structures. The Icons (The Skyline): Identify 3–5 of the city's most recognizable skyscrapers, towers, or monuments. The Substrate (The Map): Identify the specific geography (e.g., a curving river, a coastal harbor, or a peninsula). 2. Container (The Relief Map): Goal: A "Living Geographic Branding" 3D Diorama. The Base: A massive, thick topographic relief map resting on a neutral surface. The Surface: The map displays realistic textures: light blue reflective Epoxy Resin for the water and a textured, illustrated paper-map or satellite-image finish for the land. The Border: The land area is populated by tiny, low-rise urban sprawl (greebling) that surrounds the central structures. 3. The Central Composition (The Hybrid Skyline): The Typography: The letters identified in Step 1 are extruded into massive, Matte White Geometric Monoliths. They function as the "Super-Tall" skyscrapers of the city. The Integration: The real landmarks (Step 1) are placed realistically among the giant white letters, following the actual urban layout of the city relative to the water. The Merge: The foundations of the buildings and letters must look like they are physically part of the map's terrain. 4. The Narrative Detail (The Scale): Micro-Life: Densely populate the scene with scale-accuracy items: Tiny white cruise ships and speedboats in the water. A single, microscopic commercial airplane flying at low altitude over the city. Compass roses or navigation markers scattered on the map surface. The Atmosphere: 4–6 small, 3D Fluffy White Cotton-like Clouds float at mid-height, some partially obscuring the taller buildings. 5. Lighting & Atmosphere: Lighting: High-Key Studio Daylight. Bright, even illumination with soft shadows casting toward the top-right to emphasize height. Perspective: Isometric 3/4 High-Angle. Capturing the depth of the coastline and the verticality of the letters. Palette: Predominantly White, Light Blue, and Neutral Greys, with small pops of color from the real landmarks. Output: ONE image, 1:1 Aspect Ratio, 3D Architectural Render, "SimCity" aesthetic, 8k resolution. </instruction>
