章贡非遗传统绳编曼陀罗纹编织高精度三维模型产品

以 ASCII 编码存储该曼陀罗纹编织产品三维模型的几何数据，关键字段如下：顶点坐标（v）：格式 v X Y Z（单位 mm），记录章贡非遗钩针曼陀罗纹编织产品的纹理凸起顶点、边缘锁边节点等位置，如 v 0.454458 0.667905 -0.027538、v 0.469291 0.670654 -0.032602，完整呈现编织纹理的立体层次与曼陀罗纹样的细节弧度。纹理坐标（vt）：格式 vt U V，关联蓝白渐变绳线、金黄装饰纹样的色彩纹理，如 vt 0.968338 0.623613、vt 0.971006 0.622526，确保编织纹理与色彩映射精准无错位。面定义（f）：格式 f 237117/273597 237625/274152 237591/274118，共约 211 万个面，还原钩针编织的细密针脚与立体造型精度。材质引用（usemtl）：关联.mtl 材质，如 mtllib 章贡非遗曼陀罗纹编织三维模型产品.mtl。The geometric data of the 3D model of the Zhanggong intangible cultural heritage crocheted mandala-pattern braided product is stored in ASCII encoding, with the following key fields: 1. Vertex coordinates (v): Formatted as `v X Y Z` (unit: mm). This field records positions including the raised vertices of the braided texture and edge locking nodes of the product, with examples such as `v 0.454458 0.667905 -0.027538` and `v 0.469291 0.670654 -0.032602`, which fully presents the three-dimensional layers of the braided texture and the detailed curvature of the mandala pattern. 2. Texture coordinates (vt): Formatted as `vt U V`. This field associates with the color textures of the blue-white gradient rope and golden decorative patterns, with examples like `vt 0.968338 0.623613` and `vt 0.971006 0.622526`, ensuring accurate and misalignment-free mapping between the braided texture and its color distribution. 3. Face definitions (f): Formatted as `f 237117/273597 237625/274152 237591/274118`, with a total of approximately 2.11 million faces, which restores the fine stitches and high-precision three-dimensional shape of the crocheted work. 4. Material reference (usemtl): Links to .mtl format material files, with an example being `mtllib 章贡非遗曼陀罗纹编织三维模型产品.mtl`.
