3D字旅行海报

[中文]
为 [CITY] 创作一张 3:2 的高端 3D 字体旅行海报，采用奢华编辑式目的地广告风格，并融合真实感的雕塑字形建筑。城市名“[CITY]”必须是主导主体，占据画面大部分区域。将字母构建成大型、真实、三维的雕塑形态，材质可为光泽喷漆材料、抛光陶瓷、柔软石膏、雕刻石材、阳光照射的建筑表面，或适配城市特征的材料。每个字母都应在物理形态上转化为这座城市的身份象征：地标、天际线轮廓、拱门、塔楼、穹顶、桥梁、窗户、阳台、文化图案、海岸形态或街道细节必须直接从字形中生长出来。地标应感觉与建筑结构融为一体，而不是贴在文字后面或周围。塔楼可以从竖直笔画中升起，桥梁可以连接两个字母，穹顶可以形成圆形字母的曲线，屋顶可以塑造字母顶部边缘，窗户或装饰细节可以嵌入字母表面。使用低角度四分之三视角，让字体显得宏伟、电影感、高端且友好。将 3D 城市名雕塑略微放在画面偏低位置，填充海报中央和下半部分，上方保留充足留白。在顶部标题区域，添加一排精致的横向淡化地标符号，需与该城市相关：可以是微小矢量图标，或半透明建筑符号。保持它们非常柔和、优雅且次要，像高端杂志页眉细节。在每个图标下方添加对应地标名称。整体保持淡化和高级感。移除左上角任何可见的太阳。使用明亮自然日光，柔和主光来自左上方，配合轻柔补光、干净高光、细腻环境光遮蔽，以及字母下方柔和接触阴影。光线应感觉愉快、清新、编辑感，而不是阴暗或过度电影化。使用基于 [CITY] 的明亮城市适配配色：海滨城市使用水蓝、珊瑚色、奶油色和阳光黄；历史城市使用暖石色、陶土色、橄榄绿和柔和天蓝；热带城市使用绿松石色、芒果色、棕榈绿和白色；山地城市使用高山蓝、草甸绿、雪白和金色暖调；夜生活城市使用紫罗兰、青色、桃色和琥珀色。保持色彩干净、乐观、高端且克制。添加细微的编辑式文字元素来提升海报：小号大写页眉文字，例如“DESTINATION SERIES”；微小位置代码，例如“CITY / 01”；精致竖向分隔线；极简页脚文字，例如“VISIT [CITY]”；以及底部边缘附近的小号微排版坐标或期号。这些文字元素必须保持安静且次要，让大型 3D 城市名始终作为主角。背景应干净宽敞，仅使用柔和天空渐变、细腻云朵或抽象色块。不要在背景中放置额外地标；所有主要城市身份都必须来自字体本身，除了淡化的符号页眉行。风格：高端编辑式旅行广告、奢华杂志封面、真实感 3D 字体雕塑、明亮现代乐观、愉快旅行憧憬、文化身份、干净艺术指导。负面提示：避免通用旅行海报、分离式地标拼贴、地标贴在文字后方、扁平字体、杂乱背景、左上角可见太阳、过多图标、阴暗电影感光线、浑浊色彩、廉价纪念品美学、城市名不可读、字母扭曲、随机渐变、噪点纹理、图库模板式版面，以及过度装饰的旅游图形。

Create a 3:2 premium 3D typography-based travel poster for [CITY], using luxury editorial destination advertising fused with realistic sculptural letterform architecture. The city name “[CITY]” must be the dominant subject, occupying most of the canvas. Build the letters as large, realistic, three-dimensional sculptural forms made from glossy painted material, polished ceramic, soft plaster, carved stone, sunlit architectural surfaces, or city-adaptive materials. Each letter should physically transform into the city’s identity: landmarks, skyline silhouettes, arches, towers, domes, bridges, windows, balconies, cultural patterns, coastal forms, or street details must grow directly out of the letterforms. Landmarks should feel architecturally integrated, not pasted behind or around the word. A tower may rise from a vertical stem, a bridge may connect two letters, a dome may form the curve of a rounded letter, rooftops may shape the top edges, and windows or ornamental details may be embedded into the letter faces. Use a low-angle three-quarter camera view so the typography feels monumental, cinematic, premium, and friendly. Place the 3D city-name sculpture slightly low in the frame, filling the central and lower portions of the poster, with generous negative space above. At the top header, add a refined horizontal row of faded landmark symbols related to the city: tiny vector icons, or translucent architectural glyphs. Keep them very soft, elegant, and secondary, like premium magazine header details. Add each landmark name below its icon. Keep all faded and premium. Remove any visible sun from the top-left corner. Use bright natural daylight with a soft key light from the upper-left, gentle fill light, clean highlights, subtle ambient occlusion, and soft contact shadows beneath the letters. The lighting should feel cheerful, fresh, and editorial, not dark or overly cinematic. Use a bright city-adaptive palette based on [CITY]: coastal cities use aqua, coral, cream, and sunny yellow; historic cities use warm stone, terracotta, olive, and soft sky blue; tropical cities use turquoise, mango, palm green, and white; mountain cities use alpine blue, meadow green, snow white, and golden warmth; nightlife cities use violet, cyan, peach, and amber. Keep colors clean, optimistic, premium, and controlled. Add subtle editorial text elements to improve the poster: small uppercase header text such as “DESTINATION SERIES”, a tiny location code like “CITY / 01”, delicate vertical divider lines, a minimal footer line such as “VISIT [CITY]”, and small microtype coordinates or issue number near the bottom edge. These text elements must remain quiet and secondary so the large 3D city name stays the hero. Background should be clean and spacious with a soft sky gradient, delicate clouds, or abstract color field only. Do not place extra landmarks in the background; all major city identity must come from the typography itself, except the faded symbolic header row. Style: premium editorial travel advertising, luxury magazine cover, realistic 3D typographic sculpture, bright modern optimism, cheerful wanderlust, cultural identity, clean art direction. Negative prompt: avoid generic travel posters, separate landmark collages, landmarks pasted behind text, flat typography, cluttered backgrounds, visible sun in the top-left corner, excessive icons, dark cinematic lighting, muddy colors, cheap souvenir aesthetics, unreadable city name, distorted letters, random gradients, noisy textures, stock-template layouts, and overdecorated tourist graphics.
