章贡非遗根雕《岩间栖羽》高精度数字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），记录章贡非遗根雕《岩间栖羽》摆件的木雕瑞禽羽翼边缘、木理纹理节点、嵌石弧面及器物转折处等关键位置，如 v -0.015329 0.562566 -0.102992，完整还原根雕 “木理自然” 的肌理、瑞禽灵动的姿态，以及嵌石纹理的天然质感、器物 “岩间栖羽” 的古雅构图。​纹理坐标（vt）：格式 vt U V，关联章贡非遗根雕特有的木材质感、嵌石天然纹理及雕件细节肌理，如 vt 0.455656 0.793653，确保纹理映射与实体非遗根雕技艺细节无错位，精准呈现木石交融的古朴意境。​​面定义（f）：格式 f 402289/479237 402315/479270 402288/479236，共约 244 万个面保证精度，极致还原瑞禽羽翼弧度、木理细微纹路及嵌石曲面光泽等非遗技艺核心细节。​材质引用（usemtl）：关联.mtl 材质，如 mtllib 章贡非遗根雕《岩间栖羽》摆件.mtl。

Geometric data is stored in ASCII encoding, with the following core fields:
1. Vertex coordinates (v): The format is `v X Y Z` (unit: mm). This field records key positions including the edges of the carved auspicious bird's wings, wood grain texture nodes, the arc surface of the inlaid stone, and the turning points of the artifact from the Zhanggong Intangible Cultural Heritage root carving ornament *Perching Feathers in the Rock* (Yanjian Qiyu). For example: `v -0.015329 0.562566 -0.102992`, which fully restores the natural wood grain texture of the root carving, the lively posture of the auspicious bird, the natural texture of the inlaid stone, and the elegant composition of the *Perching Feathers in the Rock* ornament.
2. Texture coordinates (vt): The format is `vt U V`. This field is associated with the unique wood texture, natural inlaid stone texture and detailed carving texture of the Zhanggong Intangible Cultural Heritage root carving. For example: `vt 0.455656 0.793653`, which ensures no misalignment between texture mapping and the detailed craftsmanship of the physical intangible cultural heritage root carving, and accurately presents the quaint artistic conception of the integration of wood and stone.
3. Face definitions (f): The format is `f 402289/479237 402315/479270 402288/479236`. There are approximately 2.44 million faces in total to ensure precision, which faithfully restores the core details of the intangible cultural heritage craftsmanship such as the radian of the auspicious bird's wings, subtle wood grain lines and the luster of the inlaid stone curved surface.
4. Material reference (usemtl): Associates with the `.mtl` material file, e.g., `mtllib Zhanggong Intangible Cultural Heritage Root Carving Perching Feathers in the Rock Ornament.mtl`.
