章贡客家非遗剪纸《红色故都》高精度数字化三维模型产品

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），记录章贡客家非遗剪纸《红色故都》运用锯齿纹、月牙纹、三角纹等土著纹饰，同时结合网纹、米字纹来衔接粗细线条，如v -1.587919 7.561272 -0.007289，完整章贡客家非遗剪纸《红色故都》用阳刻线条表现墙面结构，阴刻块面呈现门窗，让建筑形态逼真立体。 ​纹理坐标（vt）：格式vt U V，关联宣纸纹样纹理，如vt 0.842826 0.998769，确保宣纸纹理映射无错位。 ​​面定义（f）：格式f 7/21 1/22 3/23 5/24，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《红色故都》.mtl。Geometric data is stored in ASCII encoding, with the following key fields: **Vertex coordinates (v):** Format: `v X Y Z` (unit: mm). This dataset records the Zhanggong Hakka Intangible Cultural Heritage Paper-cutting *The Red Former Capital*, which applies indigenous decorative patterns such as serrated patterns, crescent patterns and triangular patterns, and combines mesh patterns and rice-grid patterns to connect thick and thin lines. An example is: `v -1.587919 7.561272 -0.007289`. The complete *The Red Former Capital* paper-cut uses positive carving lines to represent wall structures, and negative carving blocks to render doors and windows, resulting in realistic and three-dimensional architectural forms. **Texture coordinates (vt):** Format: `vt U V`. It is associated with rice paper decorative textures. An example is: `vt 0.842826 0.998769`, which ensures no misalignment in rice paper texture mapping. **Face definitions (f):** Format: `f 7/21 1/22 3/23 5/24`. A total of approximately 400,000 faces are used to ensure precision. **Material references (usemtl):** Associated with .mtl material files. An example is: `mtllib Zhanggong Hakka Intangible Cultural Heritage Paper-cutting The Red Former Capital.mtl`.
