章贡客家竹雕《千重龙岁呈祥》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），记录章贡客家竹雕《千重龙岁呈祥》采用多层透雕呈现回纹、卷草纹，以高浮雕突出中心 “龙” 字纹，顶部采用镂空雕塑造云纹的结构，如v 0.22447001 0.83571101 0.081119，完整章贡客家竹雕《千重龙岁呈祥》用镂空雕塑造云纹装饰，保留刀痕肌理以营造远看似木质宫灯 近看是竹雕工艺的效果。 ​纹理坐标（vt）：格式vt U V，关联竹子纹理，如vt 0.32524 0.05355，确保竹子纹理映射无错位。 ​​面定义（f）：格式f 725229/942398 725227/941859 737750/941858，共约317万个面保证精度。​ 材质引用（usemtl）：关联.mtl材质，如mtllib 章贡客家竹雕《千重龙岁呈祥》.mtl。Geometric data is stored in ASCII encoding, with the following key fields: Vertex coordinates (v): formatted as `v X Y Z` with unit mm. This dataset corresponds to the Zhanggong Hakka bamboo carving *Qianchong Long Sui Cheng Xiang*, which adopts multi-layer openwork carving to depict fretwork and scroll patterns, uses high-relief carving to highlight the central "dragon" character pattern, and employs hollow carving at the top to create cloud pattern structures. An example entry is `v 0.22447001 0.83571101 0.081119`. The complete carving uses hollow carving for cloud pattern decoration, retains tool mark textures to create an effect that looks like a wooden palace lantern from a distance, but reveals authentic bamboo carving craftsmanship upon close inspection. Texture coordinates (vt): formatted as `vt U V`, associated with bamboo surface textures. An example entry is `vt 0.32524 0.05355`, which ensures no misalignment during bamboo texture mapping. Face definitions (f): formatted as `f 725229/942398 725227/941859 737750/941858`, with approximately 3.17 million faces to ensure high modeling precision. Material reference (usemtl): associated with .mtl material files, with an example entry being `mtllib Zhanggong Hakka Bamboo Carving Qianchong Long Sui Cheng Xiang.mtl`.
