章贡客家非遗瓷画《宋城客家风情》数字化高精度三维模型产品

以 ASCII 编码存储几何数据，关键字段如下：​顶点坐标（v）：格式v X Y Z（单位 mm），记录赣南客家非遗瓷画《宋城客家风情》章贡客家瓷画像采用“双勾针刻”专属手法，融合宋画的精准线条与客家民间绘画的质朴笔触精准勾勒结构。 如v 0.299899 0.128445 0.186110，完整赣南客家非遗瓷画《宋城客家风情》客家秘制彩料调制、多层套彩、干湿晕染，凸显硬景质感。 ​纹理坐标（vt）：格式vt U V，关联漆色纹理，如vt 0.800348 0.346408，确保纹理映射无错位。 ​​面定义（f）：格式f 258494/275034 258495/275035 258546/275086，共约206万个面保证精度。​ 材质引用（usemtl）：关联.mtl材质，如mtllib 赣南客家非遗瓷画《宋城客家风情》.mtl。Geometric data is stored in ASCII encoding, with the following key fields: 1. Vertex coordinates (v): Format: `v X Y Z` (unit: mm). This dataset corresponds to the Zhanggong Hakka porcelain painting of the intangible cultural heritage work *Hakka Porcelain Painting of Southern Jiangxi: Hakka Style of Song City*, which adopts the exclusive "double-hook needle engraving" technique. The technique combines the precise lines of Song Dynasty paintings and the simple brushstrokes of Hakka folk painting to accurately outline structural details. For example: `v 0.299899 0.128445 0.186110`. The work uses Hakka secret color formulation, with multi-layer color overlay and dry-wet dyeing to highlight the texture of hard landscapes. 2. Texture coordinates (vt): Format: `vt U V`, which is used to associate paint color textures to ensure no misalignment during texture mapping. An example is: `vt 0.800348 0.346408`. 3. Face definitions (f): Format: `f v_index/vt_index` face index pairs, e.g., `f 258494/275034 258495/275035 258546/275086`. The dataset contains approximately 2.06 million faces to guarantee high rendering precision. 4. Material reference (usemtl): Associated with `.mtl` material files, with an example command: `mtllib Hakka Porcelain Painting of Southern Jiangxi: Hakka Style of Song City.mtl`.
