| description | 平铺图转隐形模特立体图。平铺图 → 有体积感与版型的立体展示图。当用户说「转 3D」「立体图」「隐形模特」「把衣服撑起来」时使用。 |
把平摊在桌面上的服装图变成有体积感的立体图——像被一个看不见的人穿着（业内叫 ghost mannequin / 隐形模特）。
用途：平铺图便宜但显得廉价，真人图贵且不适合所有类目。3D 立体图是中间档——有质感、能交代版型，又不涉及模特成本与肖像问题。
| 输入：平铺图 |

实际执行的命令：
dlazy gpt-image-2 \
--prompt 'Turn this flat-lay garment photo into a dimensional 3D ghost-mannequin product shot. The olive-green cable-knit crewneck sweater must gain realistic volume: filled shoulders and chest, sleeves with natural bend, visible interior of the collar, soft self-shadow under the hem, as if worn by an invisible mannequin. Keep the garment 100% faithful: same olive-green colour, same cable-knit and diamond stitch pattern, same ribbed collar and cuffs, same woven cuff label. Clean seamless light-grey studio background, soft top light, sharp fibre detail. No mannequin, no person, no text.' \

输出
example-output.jpg — 1024×1024。肩胸被撑起、袖子自然弯曲、领口露出内里罗纹与背面内衬、下摆有自重投影；麻花与菱形织法、军绿色、罗纹结构与右袖织标保持不变，画面里没有出现人台或人体。
| 能力 | 说明 |
|---|---|
| 立体撑起 | 肩胸填充、袖子弯曲、领口露出内里、下摆自重投影 |
| 服装类型 | 上装 / 下装 / 连衣裙 / 外套 / 内衣 / 童装 / 家居服 |
| 形态控制 | 参考图（照抄某种立体形态）或自定义提示词 |
| 材质增强 | 开关；开启后针织、绒毛、皮革的表面细节更清晰 |
| 生成比例 | 1:1（方图主图）/ 3:4（竖版详情） |
不做：不改颜色、织法、印花与罗纹结构；不生成人体与人脸；不改变服装的实际版型比例。
生成前先自检这几条硬性约束：
推荐的输入（✅）：纯色背景、完全摊平、无褶皱堆叠、正面完整、领口与下摆边界清晰的单件平铺图。
会明显拉低效果的输入（❌）
| 问题 | 说明 |
|---|---|
| 折叠摆放 | 袖子折在身上，模型算不出袖子长度 |
| 大面积褶皱 | 褶皱会被当成结构撑成怪形状 |
| 已带人体 | 真人上身图请用 one-shot |
| 套装同框 | 拆成单件分别跑 |
| 控制点 | 写进 prompt | 不写会怎样 |
|---|---|---|
| 填充程度 | filled shoulders and chest with realistic volume, natural fabric drape | 撑得像气球，版型失真 |
| 袖子姿态 | sleeves with a natural bend, hanging slightly forward and away from the body | 袖子直挺挺贴在身侧 |
| 领口内里 | visible interior of the collar showing the inner facing | 领口是个平的洞，最容易露馅 |
再补两条环境约束：
soft self-shadow under the hem and inside the sleeves
No mannequin, no person, no visible support — the garment must appear worn by an invisible body.
No mannequin, no person 这句必须写，否则模型经常直接长出一个人台或半个身体。
本技能使用 dLazy 的 gpt-image-2（图像编辑模型；从平面推断体积需要强几何理解，同时要严格保住织法与颜色不变）。
两种等价写法，选一种。统一入口会自动选后端、失败重试、建目录落盘、估算成本：
# A. 统一入口（推荐）：可切任意后端，加 --dry-run 不计费空跑
node scripts/gen.mjs --task to-3d \
--prompt '<见下方 Prompt 模板>' \
--images <按下表顺序> \
--save output/to-3d-<sku>.jpg
# B. 直接用 dLazy CLI（不想引入 Node 依赖时，效果等价）
dlazy gpt-image-2 --prompt '...' --images ... --save output/to-3d.jpg
参数约定（本技能固定用法）
| 参数 | 取值 | 理由 |
|---|---|---|
--images | [平铺图]；带形态参考时 [平铺图, 形态参考图] | 顺序即 prompt 中的 image 1 / 2 |
--size | 1024x1024（方图主图）/ 1024x1536（竖版长款、连衣裙） | 对应原站的 1:1 / 3:4 |
--quality | high（等价于「材质增强」开启）/ medium（关闭） | 针织、绒毛类必须 high |
--imageFormat | jpeg | 电商上架通用格式 |
--batch | 2 ~ 3 | 体积推断有随机性 |
--save | docs/to-3d/output-<sku>.jpg | 直接落盘 |

按问题追加的修正句

|---|---|
| 长出了人台或半个人 | Absolutely no mannequin, torso, neck, arms or hands anywhere in the frame — only the garment. |
| 撑得过度、版型变胖 | Keep the original garment proportions: body width, sleeve length and hem width must match image 1 exactly. Add volume, not size. |
| 领口是个平的洞 | The collar opening must show the inner facing and the inside back of the garment, with correct depth and shadow. |
| 织法被抹平 | 改 --quality high，追加 resolve individual knit loops and yarn twist |
| 投影方向乱 | Single soft top-left light source; one consistent contact shadow beneath the garment. |
--quality high。--dry-run 估价 → 真跑 → --batch 2~3 挑图，落盘到 docs/to-3d/。| 现象 | 原因 | 处理 |

| 版型被撑胖 | 只说了加体积没说保比例 | 追加保比例句：Add volume, not size. |
| 领口是平的黑洞 | 未描述内里 | 追加领口内里句 |

| 织法糊了 | --quality medium | 改 high；或接 material-enhancement |
| 折叠摆放的图效果很差 | 输入违规 | 重拍成完全摊平的平铺图 |
