完整的建筑外观提示词

示例提示词使用英文。

Create a competition-quality architectural visualization of a small civic library at the edge of a public park. The building is a two-story mass composed of pale board-formed concrete volumes around a transparent central reading hall. Deep bronze-framed windows, sheltered outdoor reading terraces, and warm timber soffits make the public entrance welcoming. View the library from a pedestrian-height three-quarter angle across a shallow rain garden, using a 28mm architectural lens. Keep vertical lines straight and show the complete building with breathing room on all sides. Late-afternoon overcast light creates soft directional shadows and reveals the concrete grain without dramatic glare. Include small groups of visitors entering, reading, and sitting along the landscape edge. Keep people secondary to the architecture. The image should feel calm, civic, contemporary, and photographically believable. Presentation-ready detail.

这个提示词为什么有效

• 交付成果明确了预期精细程度和视觉层级。
• 通过可见形态、材质和功能描述建筑，而非使用含糊形容词。
• 镜头指令彼此相容：行人高度、斜侧视角、28mm 镜头、笔直竖线，以及包含完整建筑的构图。
• 光线用于呈现选定材质，不与材质争夺注意力。
• 人物的作用明确，不会意外成为画面焦点。

2. 按交付成果划分的建筑示例

照片级住宅外观

Create a photorealistic dusk exterior for a residential architecture portfolio. A low, courtyard house sits on a gently sloping coastal site. The architecture uses local limestone walls, dark anodized aluminum frames, sliding glass panels, and thin weathered-steel roof edges. Place the camera at eye level outside the courtyard, angled 35 degrees toward the main living pavilion. Use a 35mm lens with straight verticals and restrained perspective. The foreground should include native grasses and a narrow stone path leading toward the illuminated entrance. Balance cool blue-hour ambient light with warm interior light. Preserve natural material texture, realistic reflections, and plausible construction joints. Avoid exaggerated HDR, glowing vegetation, oversaturated skies, and distorted glazing.

酒店室内

Create an editorial interior photograph of a boutique hotel lobby designed around a central sunken lounge. The room has lime-plaster walls, travertine floors, dark walnut millwork, low linen seating, and a sculptural paper pendant above the lounge. Use a symmetrical frontal composition from seated eye level with a 24mm tilt-shift architectural lens. Keep the full ceiling edge and both side walls visible. Soft morning light enters from concealed windows on the left, creating gentle gradients across the plaster and subtle reflections on the stone floor. Include three guests in quiet conversation and one staff member crossing the rear of the space. Keep all figures natural, understated, and secondary to the interior design.

概念体量研究

Create a clean architectural massing study for an early design review. Show a mixed-use urban block as simplified matte-white volumes on a light-gray site base. Distinguish the residential tower, office bar, retail podium, and public courtyard using subtle tonal differences rather than labels. Use a 45-degree elevated axonometric view with parallel projection. Show surrounding streets and adjacent building envelopes as lower-detail gray context. Use soft studio lighting and short contact shadows. The result should read as a precise physical study model, not a photorealistic city rendering. Leave clear empty space on the right for presentation notes.

景观与场地策略

Create a presentation-ready oblique aerial visualization of a riverfront cultural district. Clearly show the museum, performance hall, public promenade, restored wetland, bicycle route, transit stop, and three pedestrian connections to the surrounding neighborhood. Use an elevated view looking northwest, with the river occupying the lower third and the district centered in the frame. Render buildings realistically but keep distant context subdued. Use bright overcast daylight so circulation and landscape systems remain legible. Add small, believable groups of people for scale. Do not add text or diagram arrows.

3. 参考图像、标注与保留要求

每张参考图像只有一个明确任务时，效果通常最好。不要期待模型仅凭上传顺序就能判断图像用于提供几何形态、材质、光照、氛围、角色还是风格。在 RunDiffusion 中，标注可进一步精确指出所选图像中的具体区域。

为每张参考图像明确分工

本例以 Image 1 为主图，Image 2 为材质来源，Image 3 为光照来源，Image 4 为植物配置来源。方框和圆圈准确标出应从各图取用什么，以及应用到 Image 1 的哪里。

Image 1 is the primary image. Keep its building geometry, massing, roofline, openings, proportions, entrance canopy, glazing, paving, people, camera position, composition, and every unmarked area unchanged. Use the board-formed concrete inside the blue box on Image 2 for the painted facade inside the red box on Image 1. Bring over only the pale gray color, horizontal board impressions, tie holes, joint scale, and low-sheen mineral texture. Fit that material to the existing facade geometry, perspective, scale, and lighting in Image 1. Use Image 3 for the soft overcast lighting and restrained cool-neutral color grading. Do not bring over its building, roof, windows, camera view, snow, bare trees, or winter ground conditions. Use the plants inside the green circle on Image 4 for the foreground planting inside the green box on Image 1. Bring over the silver grasses, low evergreen shrubs, white flowering perennials, and gravel palette, adapting them to the scale, perspective, season, and lighting in Image 1. Do not copy the garden layout or viewpoint from Image 4. Preserve every unmarked part of Image 1. Match its perspective, construction logic, scale, shadows, reflections, texture, and photographic grain.

使用清晰的视觉标注

RunDiffusion 的标注工具可以为每张上传图像添加标识，并准确标记其中的源元素或目标区域。为每张图像提供清晰可见的标识，例如 Image 1、Image 2、Image 3、Reference 1、Reference 2、A、B、C、1、2 或 3。然后用圆圈、方框、箭头、线条、手绘轮廓或文字标签，指出需要迁移、修改、保护的内容，或添加对象的位置。在提示词中同时引用图像和可见标注，不要只依赖“左边的区域”或“这面墙”等说法。

• 明确指出主图。通常，构图、镜头、几何形态和未标记区域都应以这张图像为准。
• 源区域或目标区域的边界很重要时，使用圆圈、方框或手绘轮廓。需要指出点位、对象、方向或放置位置时，使用箭头。
• 通过图像及其可见标记引用每个标记区域，例如 Image 1 上的红色方框、Image 2 上的蓝色圆圈，或 Reference 3 上箭头指示的区域。
• 同一图像上出现多个相似标注时，通过颜色、位置、形状、数字、字母或简短文字标签加以区分。
• 清楚说明从来源到目标的关系：指出应从辅助图像取用什么，应添加或应用到主图的哪里，以及需要迁移哪些特征。
• 说明哪些内容必须保持不变，包括周围需要保护的内容和主图中所有未标记部分。

Image 1 is the primary image. Create a finished architectural edit and remove every visible annotation graphic from the final image, including the IMAGE labels, red outline, blue circle, green box, green arrow, and all annotation text. Replace only the painted exterior-facade surfaces inside the red outline on Image 1 with the board-formed concrete inside the blue circle on Image 2. Transfer only the concrete's pale gray color, horizontal board impressions, subtle tie holes, joint scale, and low-sheen mineral texture. Keep the existing windows, openings, canopy, dark metal panels, roof edge, and construction geometry inside that outline unchanged. Fit the new material precisely to the existing perspective, edges, daylight, and shadows in Image 1. Add the modular outdoor seating inside the green box on Image 3 at the location indicated by the green arrow on Image 1. Preserve its three-seat geometry, dark bronze frame, warm-gray cushions, pale stone side surfaces, and upholstery seams. Scale and orient it naturally on the paving, parallel to the facade, with believable contact shadows. Do not copy the studio background from Image 3. Preserve every unmarked part of Image 1, including the complete massing, roofline, openings, canopy, glazing, people, foreground planting, paving, camera, crop, lighting, reflections, and photographic character. Do not copy architecture or camera information from Image 2 or Image 3. Do not show annotations in the final image.

推荐语法：[以 Image 1 为主图] + [Image 1 上的目标标记] + [Image 2、Image 3 或其他图像上的源标记] + [需要迁移的内容] + [需要保留的内容]。准确引用每个可见圆圈、方框、箭头、轮廓、颜色、数字、字母或标签。

从草图到可视化

Image 1 is the primary image and authoritative guide for the massing, roof profile, entrance position, major facade openings, and viewpoint. Convert Image 1 into a believable architectural visualization of a small mountain visitor center. Interpret the walls as dark charred timber over a concrete base, with standing seam zinc roofs and deep sheltered openings. Place the building in a high altitude meadow with sparse pines and distant granite peaks. Keep Image 1's low frontal viewpoint and left to right roof sequence. Resolve missing construction details plausibly, but do not redesign the building or add new wings. Use soft cloudy daylight.

“修改 / 保留 / 融合”模式

进行局部建筑编辑时，将新的修改指令与需要保护的条件分开。这能减少意外重新设计，并明确融合标准。

Image 1 is the primary image. Image 2 is the material reference. CHANGE Replace only the white rendered facade on Image 1 with pale gray board formed concrete based on Image 2. Bring over only the pale gray color, horizontal board impressions, subtle tie holes, joint scale, and low sheen mineral texture from Image 2. Fit the material to the existing facade surfaces and construction geometry of Image 1. Do not copy the viewpoint, crop, lighting, or surrounding content from Image 2. PRESERVE Keep the building geometry, slab edges, parapet height, window sizes, mullion spacing, landscaping, camera position, crop, time of day, and all people in Image 1 unchanged. INTEGRATION Match the perspective, surface illumination, contact shadows, reflections, weathering, and photographic grain of Image 1 so the concrete appears to belong to the original photograph.

重要提示：保留指令是一项要求，并非数学意义上的锁定。每次编辑后都要将结果与源图像对比，尤其检查窗户间距、屋顶轮廓、标志、标牌和可识别的主体特征。

高保真标志或标牌放置

本例以 Image 1 为建筑主图，Image 2 为完整标志来源。标注先确定准确的目标位置和来源，再通过提示词保护周围建筑。

Image 1 is the primary architectural image. Image 2 is the logo reference. Place the complete geometric river and arch logo inside the blue circle on Image 2 within the red box on Image 1. Keep the complete logo on the flat front facade, entirely to the left of the outside building corner. Center the logo within the marked box at a modest architectural scale, with balanced clear wall visible above, below, and on both sides. Preserve the logo's three nested arches, two angular river lines, internal spacing, silhouette, proportions, and bronze color from Image 2. Render the logo as individually mounted brushed brass pieces with restrained thickness, crisp edges, subtle contact shadows, and reflections that match the daylight on Image 1. Align every logo piece with the perspective of the flat front facade. Preserve the complete building geometry, roof, entrance canopy, windows, dark metal panels, glazing, paving, planting, people, camera position, perspective, crop, daylight, shadows, reflections, and photographic character from Image 1. Return a clean finished architectural photograph containing the building and installed logo. The finished photograph contains no image labels, boxes, circles, captions, or annotation marks.

4. 材质、光照与氛围

保留设计的材质研究

当两三项修改彼此区分清楚、视觉上相容时，通常可以在一个提示词中同时提出。这些材质方案属于相互独立的备选方案，因此应使用相同的源图像和保留指令，将每种方案分别提交为一次 RunDiffusion 生成。

Use Image 1 as the primary image. Change the exterior facade finish to warm buff brick with recessed pale mortar and bronze window frames. Keep the building design, proportions, openings, structure, camera, landscape, and neutral overcast lighting unchanged. Do not modify the massing or add decorative facade elements.

Use Image 1 as the primary image. Change the exterior facade finish to pale precast concrete panels with fine exposed aggregate and dark stainless steel joints. Keep the building design, proportions, openings, structure, camera, landscape, and neutral overcast lighting unchanged. Do not modify the massing or add decorative facade elements.

Use Image 1 as the primary image. Change the exterior facade finish to vertical thermally modified ash cladding with a clear matte finish and blackened steel trims. Keep the building design, proportions, openings, structure, camera, landscape, and neutral overcast lighting unchanged. Do not modify the massing or add decorative facade elements.

从白天转为夜景

Image 1 is the primary image. Transform Image 1 from daytime into an early evening blue hour photograph. Keep the architecture, landscaping, people, camera position, crop, and weather conditions unchanged. Lower the ambient sky brightness, introduce warm interior illumination behind occupied windows, and add restrained exterior lighting at the entrance and along the main path. Maintain physically plausible light falloff, reflections, and shadow direction. Avoid glowing edges, excessive orange light, and an unrealistically dark sky.

季节调整

Image 1 is the primary image. Change Image 1 from late summer to early winter while preserving the architecture and camera. Replace leafy deciduous vegetation with bare branches, reduce groundcover density, add a light layer of recent snow on horizontal surfaces, and show damp darkened paving where pedestrians have walked. Keep the sky overcast and the interior warmly occupied. Do not bury thresholds, paths, stairs, or drainage features under deep snow.

镜头与对焦调整

Image 1 is the primary image. Create a photorealistic exterior architectural photograph of the same contemporary single story cultural pavilion. Shift the viewpoint to the left of the position shown in Image 1 and aim the camera at the center of the entrance. Use a pedestrian eye level viewpoint, a 35 mm architectural lens, a level camera, and straight vertical lines. Compose the image with the entrance slightly right of center. Reveal more of the left entrance glazing and left facade than Image 1 while keeping only a narrow portion of the right return wall visible. Keep the complete roof line inside the frame. Keep the foreground grasses low in the composition and the entrance fully visible. Preserve the exact building massing, roof profile, openings, dark bronze entrance canopy, glazing system, pale facade material, paving layout, planting species, number of people, daylight, weather, and photographic character from Image 1. Keep the people performing the same activities in positions that remain physically consistent with the new viewpoint. Match the source exposure, shadow direction, reflections, material texture, and photographic grain. Preserve the complete architecture, facade materials, landscape design, season, and weather.

避免相互矛盾的镜头指令

• 避免同时要求极广角近景和完全没有透视夸张。
• 避免在要求浅景深的同时，又要求从前景到地平线的每个平面都完全清晰。
• 避免同时要求完全对称的立面正视图和明显的斜侧视图。
• 如果几何准确性比戏剧效果更重要，应优先要求笔直竖线、清晰边缘、包含完整建筑的构图，以及克制的镜头描述。

5. 示意图、文字与事实性视觉内容

建筑解释示意图

Image 1 is the primary image. Preserve the complete architectural section geometry, roof slope, overhang, glazing, ventilation openings, floor slab, foundations, gutter, downspout, underground tank, bioswales, crop, and image boundaries. Add one blue airflow arrow that enters through the low opening on the right, crosses the central room, rises through the room, and exits through the high opening on the left. Add one warm yellow summer sun ray from the upper right. The ray must strike the top of the deep roof overhang and stop before reaching the glazing. Add one warm yellow winter sun ray from the upper right at a lower angle. The ray must pass beneath the roof overhang, pass through the glazing, and reach the interior floor. Add one teal water path that begins at the right roof gutter, continues down the right downspout, and enters the underground storage tank. Add a teal outlet path from the tank to both planted bioswales. Add exactly five labels, each appearing once: "CROSS VENTILATION" at the upper left, connected to the blue airflow arrow. "WINTER SUN" at the upper center, connected to the low yellow ray. "SUMMER SHADE" at the upper right, connected to the high yellow ray and roof overhang. "BIOSWALE" below the left planted basin. "RAINWATER STORAGE" below the underground tank. Use uppercase geometric sans serif text with one consistent size. Use thin leader lines only where stated. The five specified labels are the complete text content. Preserve the complete building drawing from Image 1.

标牌与文字排版

Image 1 is the primary image. Add the exact text "RIVER ARTS CENTER" to the front vertical face of the dark bronze entrance canopy directly above the central glazed entrance. Set the complete name on one line in uppercase brushed aluminum sans serif letters. Center the sign directly over the central entrance doors. Keep the lettering modest in scale with generous dark bronze fascia visible above, below, and at both ends of the sign. Align the baseline with the lower edge of the canopy. Render the letters as individually mounted metal characters with restrained depth, soft contact shadows, and reflections that match the existing daylight. Preserve the building geometry, entrance canopy, glazing, materials, paving, planting, people, camera position, perspective, crop, lighting, shadows, reflections, and photographic character from Image 1. The finished photograph contains this sign as the only added element.

图中文字本地化

对图像中的文字进行本地化时，应在生成前准备并确认译文。完整写出文字最终应呈现的准确内容，不要让 Nano Banana Pro 代为翻译。

Use Image 1 as the primary image. Change only the text on the wayfinding sign. Replace "VISITOR CENTER" with: "ศูนย์บริการนักท่องเที่ยว" Replace "ENTRANCE" with: "ทางเข้า" Replace "RESTROOMS" with: "ห้องน้ำ" Use the Thai copy exactly as written. Preserve the sign panel, text hierarchy, divider line, arrows, colors, placement, background, architecture, camera, lighting, and all other parts of Image 1. Adjust the spacing and line breaks only as needed to make the Thai text clear and properly balanced within the existing sign.

使用本地化图像前，逐一核对每个字符、换行、箭头和标签。如果文字有误，在新的 RunDiffusion 调用中将当前图像作为 Image 1，仅请求必要的文字修正。

经核实背景信息的示例

经核实的背景信息，是指在生成前确定哪些设计信息已获确认，再将其转化为直接的视觉指令。本例在一座庭院建筑上表达六项概念策略：遮阳、穿堂通风、冷屋顶、树冠、生态植草沟和屋面排水。提示词准确指定建筑视图、可见系统、示意图颜色、箭头和标签，不添加统计数据、规范要求或性能声明。应将结果作为概念性的建筑沟通图形进行检查，不能视为经验证的项目性能。

Create a clean architectural climate strategy infographic showing one contemporary low rise civic building. Use a three quarter axonometric view of the complete building and its immediate landscape on a clean warm white background. Arrange the building around a planted central courtyard. Show broad light colored roof planes, deep overhangs with warm yellow shading accents, a long covered walkway across the foreground, wood toned exterior walls, large openings on both side wings, mature trees within and around the courtyard, and a planted bioswale along the front right edge. Use refined architectural linework, soft neutral materials, restrained color, and a clear presentation style. Show cross ventilation with large blue arrows at openings on the left and right sides of the building. Show roof drainage as a visible teal system following roof edges, downspouts, and ground channels toward the bioswale. Use muted green for the tree canopy and bioswale. Add exactly these six labels, each once: "SOLAR SHADE" "CROSS VENTILATION" "COOL ROOF" "TREE CANOPY" "BIOSWALE" "ROOF DRAINAGE" Place the labels around the outside of the building and connect each one to the correct feature with a simple black leader line or arrow. Render every label exactly as written with clear uppercase black sans serif typography. Keep this as one integrated building diagram. Do not add a title, location name, statistics, citations, dimensions, legends, extra labels, logos, separate detail panels, or other text.

背景信息核查清单

• 确认经批准的背景资料能直接支持图像中使用的每项事实或统计数据。
• 区分实测气候数据、设计建议和说明性概念。
• 核对日期、单位、地点、季节假设及所有翻译后的标签。
• 删除缺乏依据的精确表述，避免图形暗示未经证实的确定性。
• 即使图像本身保持简洁，也应在项目记录中保留支持性文档。

6. 分轮聚焦编辑，逐步完善图像

在 RunDiffusion 上，每次生成都是不带对话历史的全新调用。因此，分轮编辑意味着以当前最理想的图像作为下一次编辑的底图，并在每次调用中编写完整、独立的指令。重新附上所需参考图像，重申必须保持不变的内容，并在完善展示细节前确定主要设计决策。

RunDiffusion 工作流：生成或上传 Image 1，检查图像，并按需使用圆圈、方框、箭头、线条、轮廓、颜色、数字、字母或标签标记源区域和目标区域。提交 Image 1 及所有必要辅助图像，进行下一次针对性编辑。重复该过程，直到达到目标。

图像瑕疵

反复编辑偶尔会引入细小瑕疵、扭曲像素或变软的细节。通常可通过 Topaz Generative Upscaler、Magnific Upscaler 等生成式放大工具修正，或使用 ChatGPT Image 2.0 进行一次针对性处理。另一种方法是在 Photoshop、Krita 或常用图像编辑器中，将编辑成功的区域合成到上一张干净源图上。擦除修正区域以外的所有内容，合并图层，再将干净的合成图作为 Nano Banana Pro 下一次编辑的底图。这样既能保留成功的修改，也能限制反复生成造成的画质退化累积。

针对性的后续修改

Image 1 is the primary image. Create a photorealistic exterior architectural photograph of the same contemporary pavilion. Change only the pale board formed concrete on the main front facade and the right return facade. Refine the surface into a visibly finer horizontal formwork pattern with narrower boards, closer spacing, and more consistent courses than Image 1. Keep every board horizontal. Retain subtle tie holes and construction joints aligned correctly across each facade plane. Give the concrete a matte mineral surface with restrained reflectance. Retain the existing pale gray color and subtle tonal variation while keeping highlights soft. Preserve the exact camera position, perspective, crop, image boundaries, building massing, roof, dark bronze canopy, glazing, paving, planting, people, lighting, shadow direction, and every material other than the pale concrete. Keep the roof apex, building edges, people, and foreground grass line in the same locations within the frame. Match the refined concrete to the existing perspective, scale, edges, shadows, and photographic grain. Limit the edit to the pale concrete surface while every other part of Image 1 remains unchanged.

Image 1 is the primary image. Remove two foreground people and leave a calm, open area of uninterrupted paving around the entrance. Preserve the architecture, camera, crop, materials, lighting, and all other people in Image 1.

Image 1 is the primary image. Create a photorealistic exterior architectural photograph of the same contemporary pavilion. Change only the light and weather. Replace the blue sky with continuous pale gray cloud cover and change the scene to bright, soft overcast daylight. Replace the crisp directional shadows with broad soft shadows directly beneath the entrance canopy, people, and foreground grasses. Keep the facade and paving evenly illuminated with gentle tonal gradients. Retain softened glazing reflections. Maintain the same neutral color balance and overall exposure as Image 1. Preserve the exact building geometry, roof, openings, materials, canopy, glazing, paving, planting, number and positions of people, camera position, perspective, crop, image boundaries, and complete composition from Image 1.

Image 1 is the primary image. Correct only the misspelled entrance sign so it reads exactly "LIBRARY". Preserve the complete scene, sign position, typography, materials, shadows, camera, and crop of Image 1.

何时重新开始

当反复编辑导致几何形态、主体特征或构图偏移时，回到上一张可靠图像。将这张更理想的源图作为新调用的底图，重新附上辅助参考图，并再次描述其受保护特征。从可靠图像重新开始，通常比尝试撤销多次叠加的修改更有效。

7. 将框架应用到其他设计领域

本指南以建筑为主要重点，但 Nano Banana Pro 通过自然语言生成和编辑图像的方法，也支持密切相关的创意工作。核心结构保持一致，各领域需要明确的视觉决策有所不同。

室内设计

提示词公式：房间类型 + 空间布局 + 固定建筑元素 + 家具 + 材质 + 光照方向 + 视点 + 配色 + 陈设细节 + 需要保留的元素

Create an editorial interior photograph of a compact urban apartment living room. The left wall is continuous floor to ceiling glazing that extends directly from the finished oak floor to the underside of the flat ceiling. Divide the glazing into four tall bays with slim dark bronze mullions. Include exactly one exposed rectangular concrete structural column at the right third of the room. Keep every other structural surface finished in warm white lime plaster. Finish the floor in natural oak. Place a low three module oatmeal sofa centered on the rear wall. Place two sculptural lounge chairs facing the sofa with a pale rectangular travertine coffee table centered between them. Mount a slim floating oak media cabinet on the right wall opposite the seating. Place one muted rust textile on the sofa. Keep an open circulation aisle between the glazing and the seating, plus a clear route from the foreground to the doorway at the rear right. All furniture must be correctly scaled and must not obstruct either route. Position the camera at 1.25 meters above the floor, centered on the seating group. Use a 28 mm architectural lens with straight vertical lines. Show the complete left glazing wall, rear wall, single concrete column, seating group, and circulation aisle. Use soft late morning daylight entering through the glazing on the left. Retain exterior detail through the glass with balanced highlights. Keep the editorial styling limited to the specified architecture, furniture, finishes, and textile.

室内设计重点：修改家具、陈设、材质或光照之前，先保护房间围护结构。当窗户、门、固定家具、天花几何形态、相机位置和流线属于设计约束时，应明确要求保留。

景观建筑

提示词公式：场地类型 + 流线层级 + 竖向设计或水管理策略 + 植物群落 + 硬质景观 + 功能 + 季节 + 光照 + 视点 + 氛围

Create a competition-quality landscape visualization of a climate-resilient civic plaza. Organize a clear pedestrian route from the street to the library entrance, with a shaded gathering terrace on the right and a planted rain garden occupying the lower foreground. Use permeable warm-gray pavers, board-formed concrete seat walls, native canopy trees, silver-green grasses, and seasonal flowering plants suitable for a hot-humid climate. Show the rain garden as a functioning shallow planted basin with visible inlets, not as a decorative pond. Use a pedestrian-height wide composition in bright overcast daylight. Include small groups walking, sitting, and gathering beneath the trees. Keep all paths accessible and maintain clear sightlines to the entrance.

景观设计重点：既描述外观，也描述系统，包括流线、竖向设计、排水、遮阴、生境、植物结构、季节、维护特征，以及景观与建筑之间的关系。

插画

提示词公式：交付成果 + 主体 + 叙事情境 + 构图 + 媒介 + 笔触表现 + 配色 + 光照逻辑 + 文字 + 排除项

Create an editorial illustration for an article about cities adapting to extreme heat. Show a cross section like urban street where mature shade trees, arcades, reflective roofs, water sensitive planting, and active ground-floor spaces work together to cool the public realm. Use a sophisticated cut-paper and gouache style with simplified geometric forms, visible paper texture, restrained shadows, and a palette of terracotta, deep green, warm cream, and muted blue. Compose the image as a wide horizontal scene with people moving through several layers of shade. Keep the environmental ideas understandable without turning the image into a technical diagram. Do not include text.

插画重点：明确媒介及其可见表现。“插画风格”过于含糊；纸张纹理、墨线轮廓、平涂色块、半色调、绘画式边缘、拼贴叠层和线条粗细才是具体指令。

广告与宣传视觉素材

提示词公式：宣传目标 + 产品或主体 + 受众 + 创意 + 构图 + 品牌素材 + 准确文案 + 光照 + 形式 + 受保护的品牌规则

Create a polished launch advertisement for a modular outdoor seating collection aimed at architects and hospitality designers. Image 1 is the authoritative product image. Preserve the exact three seat modules, three back cushions, dark bronze frame and legs, cushion proportions, upholstery seams, warm gray fabric, and both pale limestone side tables. Show the complete, unobstructed left table and complete, unobstructed right table. Center the complete product in the lower middle of the advertisement. Show it from the same front three quarter viewpoint as Image 1 with every foot grounded. Make the seating collection the dominant focal point while leaving generous negative space above it and clear margins on both sides. Place the product in a contemporary courtyard with pale limestone paving, textured warm white plaster walls, sparse ornamental grasses, and warm late afternoon light. Use realistic contact shadows beneath every leg and table. Match the product perspective, material reflections, and lighting to the courtyard. Image 2 is the authoritative RunDiffusion logo. Place the complete logo once at the bottom center within a shallow dark navy footer. Give the logo comfortable clear space on every side. Preserve the exact purple symbol, white RunDiffusion wordmark, spelling, letter shapes, spacing, colors, proportions, and relationship between the symbol and wordmark. Place the exact headline "DESIGNED TO GATHER" at the top center in large uppercase geometric sans serif text. Place the exact subheading "Modular Outdoor Collection" directly below it in smaller regular weight text. Keep both lines within clear negative space above the product and architecture. Preserve the complete referenced furniture design and materials. The finished advertisement contains one product, one complete logo, the headline, and the subheading as its complete content.

广告重点：先明确传播任务。定义受众、层级、文案、留白、品牌素材、渠道形式，以及产品或品牌识别系统中不可改变的内容。

产品设计

提示词公式：产品类别 + 形态与比例 + 部件 + 材质与饰面 + 制造细节 + 交互方式 + 背景 + 光照 + 视点 + 受保护的几何形态

Create a studio design-review image of a compact countertop air purifier. The product has a soft rectangular body with rounded vertical corners, a recessed dark intake band around the lower third, a removable perforated top grille, and one small circular control with a subtle status light. Use warm matte off-white polymer for the main shell, fine charcoal mesh behind the intake, and a satin anodized-aluminum control. Show a three-quarter front view at slightly elevated eye level on a neutral warm-gray background. Use broad diffused studio lighting that reveals the curvature, part lines, grille depth, and material differences without dramatic reflections. Keep the product isolated and fully visible.

产品参考图编辑

Image 1 is the primary product image and remains authoritative for the complete product design, viewpoint, and composition. Preserve its exact wide rectangular shape, low proportions, outer silhouette, corner radii, top grille, recessed lower intake opening, control position, panel seams, camera, crop, background, lighting, and composition. Use Image 2 only as a color, material, and finish reference. Transfer its glossy black polymer finish to the main outer shell of Image 1. Use its dark charcoal mesh character for the existing recessed intake on Image 1 and its satin metal character for the existing circular control on Image 1. Fit these finishes to the existing surfaces, components, perspective, reflections, highlights, and shadows of Image 1. The finished product retains every form, proportion, component, seam, opening, control, and design relationship from Image 1. Only its color, material, and finish change.

产品设计重点：区分形态与饰面。若任务是探索颜色、材质和饰面，在改变表面处理之前，先保护几何形态、接缝、控制件、标志、通风口和装配关系。

8. 常见问题与修正方法

• 建筑被重新设计：提出材质或光照编辑要求前，先保护体量、洞口、屋顶、结构、镜头、裁切范围和比例。
• 窗户或竖梃发生偏移：明确准确数量、间距、对齐关系和基准参考图像。必要时，从最可靠的源图像重新开始。
• 视图显得失真：使用一组相容的镜头说明，包括视点高度、大致焦距、笔直竖线和包含完整建筑的构图。
• 材质显得不真实：描述模块尺寸、接缝方式、光泽、风化、边缘状态和对光线的响应。
• 人物主导画面：明确其数量、位置、活动、尺度和次要视觉角色。
• 标牌拼写错误：先确认准确文案并用引号写出，禁止额外文字，每次编辑只修正一个文字元素。
• 示意图看似权威却内容错误：提供经核实的源资料，并独立检查每项事实。

提示词质量检验

生成前先判断：建筑师、摄影师或可视化艺术家能否直接执行这份说明，而不必猜测哪条指令最重要？如果不能，先消除歧义，再添加更多形容词。

先描述期望状态

在 RunDiffusion 上为 Nano Banana Pro 编写提示词时，应先描述画面中应出现什么，再列出不应出现的内容。正向场景描述为模型提供可构建的构图，而冗长的禁止清单可能与主要任务说明相互干扰。

推荐：宁静、开阔的步行前广场，铺装连续，入口视线通畅，植物仅布置在周边。

效果较弱：不要汽车、不要杂物、不要围栏、前方不要花箱，不要有人挡住入口。

建筑提示词原则：用正向语言描述预期场景、流线、可见性、材质表现和氛围。简短的“不要”指令应保留给严格保留要求、禁止额外文字、避免意外重新设计，以及无法仅通过描述期望结果来充分明确的其他要求。

图像编辑模型的更多技巧

Nano Banana Pro 需要很长的提示词吗？

不需要。简单图像通常更适合简短、明确的提示词。只有当增加文字能解决某项可见决策、建立关系、保护重要特征或避免歧义时，才需要加长。

应如何引用上传的图像和标注？

为每张上传图像清晰标明 Image 1、Image 2、Image 3、Reference 1、A、B、C、1、2、3，或其他可见图像名称。说明哪张是主图。用圆圈、方框、箭头、线条、轮廓、颜色、数字、字母或简短标签标记准确的源区域和目标区域。在提示词中同时引用图像和可见标记，例如“Image 1 上的红框”“Image 2 上的蓝色圆圈”或“Image 1 上箭头指示的位置”。

Nano Banana Pro 能精确保留建筑几何形态吗？

它可以较好地保留重要细节，但保留指令并非数学意义上的锁定。应将每个结果与源图像对比，尤其检查体量、屋顶轮廓、洞口、窗框竖梃、标牌和相机位置。

应该在一个提示词中完成所有编辑吗？

不一定。Nano Banana Pro 通常能在一条 RunDiffusion 提示词中处理两三项定义清晰、视觉相容的修改。指出每个目标，分别描述每项修改，并说明必须保持不变的内容。当修改相互冲突、涉及复杂几何形态或导致结果不一致时，应拆分为多次针对性生成。RunDiffusion 的每次生成都是不带对话历史的全新调用，因此每次都要提交当前最理想的图像，并重申所有必要背景、参考图分工、修改内容和保留指令。

这些技巧可以用于建筑以外的领域吗？

可以。同一方法适用于室内、景观建筑、插画、广告和产品设计。将建筑专用字段替换为该领域需要明确的视觉决策即可。

生成的示意图或建筑视觉图像能当作经验证的技术信息吗？

不能。应独立核实事实、尺寸、规范要求、环境声明、工程行为和数据。除非通过适当的专业审查，否则生成图像只是设计与沟通辅助工具。
