章贡客家非遗剪纸《双龙祥瑞》高清三维数字化模型产品

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），记录章贡客家非遗剪纸《双龙祥瑞》采用对折剪纸技法，勾勒半幅龙纹得到完整对称的结构，如v 2.213498 7.561272 0.007289，完整章贡客家非遗剪纸《双龙祥瑞》用锯齿纹表现鳞片，卷草纹勾勒轮廓曲线，象征中华民族的权威与祥瑞。
​纹理坐标（vt）：格式vt U V，关联纸纹样纹理，如vt 0.997159 0.493377，确保纸纹理映射无错位。
​​面定义（f）：格式f 1/1 2/2 4/3 3/4，共约40万个面保证精度。​
材质引用（usemtl）：关联.mtl材质，如mtllib 章贡客家非遗剪纸《双龙祥瑞》.mtl。

Geometric data is stored in ASCII encoding, with key fields as follows:
1. Vertex coordinates (v): The format is `v X Y Z` (unit: mm). This records the Zhanggong Hakka intangible cultural heritage paper-cutting work *Double Dragons Auspiciousness*, which adopts the folded paper-cutting technique to draw half of the dragon pattern to create a complete symmetrical structure. An example is: `v 2.213498 7.561272 0.007289`. The complete *Double Dragons Auspiciousness* paper-cut uses serrated patterns to depict scales and foliate scroll patterns to outline contour curves, symbolizing the authority and auspiciousness of the Chinese nation.
2. Texture coordinates (vt): The format is `vt U V`, which is used to associate paper pattern textures. An example is: `vt 0.997159 0.493377`, ensuring no misalignment during paper texture mapping.
3. Face definition (f): The format is `f 1/1 2/2 4/3 3/4`. Approximately 400,000 faces are included to ensure precision.
4. Material reference (usemtl): Used to associate with .mtl material files, with an example command: `mtllib Zhanggong Hakka Intangible Cultural Heritage Paper-cutting Double Dragons Auspiciousness.mtl`.
