章贡非遗玉雕《虎符》古纹玉饰数字三维模型产品

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），记录章贡非遗玉雕《虎符》古纹玉饰的虎符纹路边缘、玉饰弧面转折、古纹细节节点等关键位置，如 v27.341051 14.036078 315.114136，完整还原黄玉 “凝脂温润” 的质感、虎符古纹 “精刻细缕” 的形态，以及章贡非遗琢玉技艺中玉饰弧面的流畅肌理。 ​纹理坐标（vt）：格式 vt U V，关联黄玉天然温润光泽、虎符古纹的刻缕纹理，如 vt 0.539217 0.689487，确保纹理映射与实体非遗玉雕的玉质、纹细节无错位，精准呈现古纹虎符玉饰的传统器用美学。 ​​面定义（f）：格式 f 20194/22250/20194 20209/22286/20209 19021/22018/19021，共约 14万个面保证精度，极致还原虎符古纹的缕刻弧度、玉饰弧面的细腻转折等非遗琢玉技艺核心细节。 ​材质引用（usemtl）：关联.mtl 材质，如 mtllib 章贡非遗玉雕《虎符》古纹玉饰.mtl。Stored geometric data in ASCII encoding, with the following key fields: Vertex coordinates (v): Format: `v X Y Z` (unit: mm). This records key positions such as the edges of the tiger-fu pattern of the Zhanggong Intangible Cultural Heritage jade carving *Tiger Fu* ancient pattern jade ornament, the turning points of the jade ornament's curved surface, and the detail nodes of the ancient patterns. For example: `v 27.341051 14.036078 315.114136`. It fully restores the "greasy, warm" texture of the yellow jade, the "precisely carved and finely detailed" shape of the tiger-fu ancient patterns, as well as the smooth texture of the curved surface of the jade ornament in the Zhanggong intangible cultural heritage jade carving technique. Texture coordinates (vt): Format: `vt U V`. This is associated with the natural warm luster of yellow jade and the carved texture of the tiger-fu ancient patterns. For example: `vt 0.539217 0.689487`. It ensures that texture mapping does not misalign with the jade quality and pattern details of the physical intangible cultural heritage jade carving, and accurately presents the traditional utensil aesthetics of the ancient pattern tiger-fu jade ornament. Face definitions (f): Format: `f 20194/22250/20194 20209/22286/20209 19021/22018/19021`. There are approximately 140,000 faces to ensure precision, which extremely restores the core details of the intangible cultural heritage jade carving technique, such as the carved radian of the tiger-fu ancient patterns and the delicate turning points of the jade ornament's curved surface. Material reference (usemtl): Associated with the .mtl material file, e.g., `mtllib Zhanggong Intangible Cultural Heritage Jade Carving *Tiger Fu* Ancient Pattern Jade Ornament.mtl`.
