章贡客家竹雕《客韵龙腾》高清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），记录章贡客家竹雕《客韵龙腾》竹子表层青筠雕刻龙字与龙纹，以竹肌的深棕色为底色，青筠的厚薄变化强化字体与纹样的立体感，如v 0.087099 0.987674 0.002929，完整章贡客家竹雕《客韵龙腾》顶部云纹、底部水纹与主体龙纹呼应，保留刀痕肌理以营造 远看似天然纹饰、近看是精细雕刻的效果。 ​纹理坐标（vt）：格式vt U V，关联竹子纹理，如vt 0.868806 0.900098，确保竹子纹理映射无错位。 ​​面定义（f）：格式f 738590/818791 136272/818793 738591/818794，共约308万个面保证精度。​ 材质引用（usemtl）：关联.mtl材质，如mtllib 章贡客家竹雕《客韵龙腾》.mtl。Geometric data is stored in ASCII encoding, with key fields as follows: Vertex coordinates (v): Follow the format `v X Y Z` with the unit of millimeter (mm). This dataset documents the Zhanggong Hakka bamboo carving *Keyun Longteng*, where dragon characters and dragon motifs are carved on the green cuticle of the bamboo. The dark brown bamboo flesh serves as the background color, and the thickness variations of the green cuticle enhance the three-dimensionality of the characters and motifs. A sample entry is: `v 0.087099 0.987674 0.002929`. The complete carving includes cloud patterns at the top and water patterns at the bottom that echo the main dragon motifs, while retaining the tool-cut texture to create an effect that looks like natural decorative patterns at a distance but reveals intricate carving upon close inspection. Texture coordinates (vt): Follow the format `vt U V`, which is used to associate bamboo textures. A sample entry is: `vt 0.868806 0.900098`, ensuring no misalignment during bamboo texture mapping. Face definitions (f): Follow the format `f 738590/818791 136272/818793 738591/818794`. A total of approximately 3.08 million faces are used to guarantee the model's precision. Material reference (usemtl): Associated with .mtl material files. A sample entry is: `mtllib 章贡客家竹雕《客韵龙腾》.mtl`
