章贡客家非遗剪纸《囍呈富贵》高清数字化3D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《囍呈富贵》曲线轮廓龙凤弧线、花卉卷叶的修整，两者结合使线条精准、细节生动，如v 2.463201 -0.161339 -0.007289，完整章贡客家非遗剪纸《囍呈富贵》龙凤呈祥花开富贵等纹样，传递客家婚庆中婚姻美满、家庭和睦的祈福。 ​纹理坐标（vt）：格式vt U V，关联纸纹样纹理，如vt 0.008488 0.009056，确保纸纹理映射无错位。 ​​面定义（f）：格式f 1/17 2/14 4/21 3/23，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《囍呈富贵》.mtl。Geometric data is stored in ASCII encoding, with the following key fields: Vertex coordinates (v): Follow the format `v X Y Z` (unit: mm). This field records the refinement of the dragon-phoenix arcs and floral curled leaf contours of the Zhanggong Hakka Intangible Cultural Heritage paper-cutting work *Xi Cheng Fu Gui*. The combination of these refined elements ensures precise lines and vivid details, as exemplified by `v 2.463201 -0.161339 -0.007289`. The complete patterns including dragon-phoenix harmony and blooming prosperity of *Xi Cheng Fu Gui* convey the blessings of happy marriage and family harmony in Hakka wedding traditions. Texture coordinates (vt): Follow the format `vt U V`, which are associated with the textures of the paper patterns. An example is `vt 0.008488 0.009056`, which ensures no misalignment during paper texture mapping. Face definitions (f): Follow the format `f 1/17 2/14 4/21 3/23`, with approximately 400,000 faces to guarantee sufficient modeling precision. Material reference (usemtl): Associated with .mtl material files, as shown in the example `mtllib Zhanggong Hakka Intangible Cultural Heritage Paper-cutting Xi Cheng Fu Gui.mtl`.
