收藏资源简介：
以 ASCII 编码存储的章贡非遗玉雕《幽居听松》高精度数字化三维模型产品几何数据如下： 顶点坐标（v）：格式 v X Y Z（单位 mm），记录印身方柱轮廓、顶部绳结纹理及印面篆字细节，如 v -0.120027 0.844265 0.105358（绳结螺旋纹理顶点）、v 0.199854 0.350496 -0.101701（印面篆字笔画顶点），精准还原章贡玉雕印章的形制与雕刻细节； 纹理坐标（vt）：格式 vt U V，关联印身红褐石色与绳结青绿纹理，如 vt 0.707188 0.993498（印身石色渐变映射）、vt 0.699181 0.982966（绳结纹理坐标），确保玉石温润质感与绳结纹理的精准匹配； 面定义（f）：格式 f 392939/419845 392940/419846 393070/419979，共约 233 万个面，细腻呈现印身方直轮廓、绳结螺旋层次及印面篆字的笔画棱角； 材质引用（usemtl）：关联材质文件，如 mtllib 章贡非遗玉雕《幽居听松》.mtl，匹配天然玉石的光泽与绳结配饰的质感参数。
High-precision digital 3D model geometric data of the Zhanggong Intangible Cultural Heritage jade carving *Living in Seclusion Listening to Pines* stored in ASCII encoding is as follows: Vertex coordinates (v): Follow the format `v X Y Z` with the unit of millimeter (mm). This data records the square column outline of the seal body, the top rope knot texture, and the seal script details on the seal face. Representative examples include `v -0.120027 0.844265 0.105358` (vertex of the spiral rope knot texture) and `v 0.199854 0.350496 -0.101701` (vertex of the seal script strokes on the seal face), accurately restoring the shape and carving details of the Zhanggong jade carving seal; Texture coordinates (vt): Follow the format `vt U V`, which associates the reddish-brown stone color of the seal body with the cyan-green texture of the rope knot. Representative examples include `vt 0.707188 0.993498` (gradient mapping of the seal body stone color) and `vt 0.699181 0.982966` (texture coordinates of the rope knot), ensuring precise matching between the warm and moist texture of natural jade and the rope knot texture; Face definitions (f): Follow the format `f 392939/419845 392940/419846 393070/419979`, with a total of approximately 2.33 million faces, which delicately presents the straight square outline of the seal body, the spiral layers of the rope knot, and the stroke edges of the seal script on the seal face; Material reference (usemtl): Associates with material files, such as `mtllib Living_in_Seclusion_Listening_to_Pines_(Zhanggong_Intangible_Cultural_Heritage_Jade_Carving).mtl`, which matches the luster parameters of natural jade and the texture parameters of the rope knot accessories.
