|
+阶段判断规则（严格执行，从后向前判断）：
|
|
|
+
|
|
|
+**第一步：判断是否为post_process（照片级后期）**
|
|
|
+✅ post_process的特征（满足3项以上即为后期）：
|
|
|
+ - 照片级真实感，无法分辨是否为渲染图
|
|
|
+ - 光影自然柔和，无明显CG痕迹
|
|
|
+ - 细节丰富真实（布料褶皱、木纹纹理、金属反射）
|
|
|
+ - 色彩自然，无过度饱和或过度对比
|
|
|
+ - 景深效果自然（前景清晰，背景自然虚化）
|
|
|
+ - 材质表现真实（大理石纹理、玻璃透明度、金属质感）
|
|
|
+ - 整体画面像单反相机拍摄的照片
|
|
|
|
|
|
-- white_model: 统一灰白色/浅色，无材质纹理细节（可有家具和灯光）
|
|
|
+**第二步：排除post_process后，判断是否为rendering（CG渲染）**
|
|
|
+❌ rendering的特征（明显CG感）：
|
|
|
+ - 明显的计算机渲染痕迹（过于完美、过于规整）
|
|
|
+ - 光影对比过强或过于均匀（V-Ray/3dsMax典型特征）
|
|
|
+ - 颜色过于饱和或过于艳丽
|
|
|
+ - 材质反射过于理想化（过于光滑、过于规则）
|
|
|
+ - 阴影边缘过于清晰或模糊不自然
|
|
|
|
|
|
-- soft_decor: 有真实材质纹理（木纹/布纹），有装饰色彩，但CG感不强
|
|
|
- ⚠️ 关键：软装可以有灯光！重点是材质真实但CG渲染感不强
|
|
|
+**第三步：判断soft_decor和white_model**
|
|
|
+- soft_decor: 有材质纹理和色彩，但CG感不强（偏手绘或简单渲染）
|
|
|
+- white_model: 灰白色调，无材质细节
|
|
|
|
|
|
-- rendering: 有材质纹理，有装饰色彩，CG计算机渲染感明显（V-Ray/3dsMax）
|
|
|
- ⚠️ 区分：rendering = CG感明显（能看出是3D渲染），质量70-89分
|
|
|
+**判断原则**：
|
|
|
+⚠️ 如果无法确定是rendering还是post_process，优先选择post_process
|
|
|
+⚠️ 现代高质量渲染图（超写实风格）应归类为post_process
|
|
|
+⚠️ 只有明显看出CG痕迹的才是rendering
|
|
|
|
|
|
-- post_process: 照片级真实感（看起来像真实拍摄），质量≥90分
