东方瑰宝金铜佛像《四大天王南方增长天王》高精度三维数字模型数据集

（一）实质性加工
数据清洗与优化：针对 OBJ 格式模型，结合增长天王 “铠甲复杂纹饰 + 手持宝剑” 特征，定向排查并删除扫描产生的冗余顶点（如铠甲鳞片间隙的无效数据）、重叠面（如宝剑与手部衔接处），在保留细节的前提下减少 30% 数据量，提升模型加载与渲染速度，满足多场景流畅运行需求。
纹理映射调整：依据金铜鎏金材质特性，精确校准纹理坐标，确保铠甲鎏金纹理、宝剑金属光泽贴合模型表面，避免拉伸、错位；按应用场景调整分辨率：学术研究保留 4K 纹理以呈现材质细节，大众传播压缩至 2K，平衡视觉效果与运行性能。
（二）创造性劳动
模型精细化处理：用 Geomagic 软件消除叠面、交叉面，对铠甲鳞片、宝剑刃部进行 “网格优化”，在保证形态精准的前提下减少三角面数量；针对手部持剑的受力姿态，通过调整关节曲率参数，确保姿态自然且符合造像规范。
表面与纹理优化：运用 AI 自适应滤波算法处理扫描噪点，重点保留鎏金材质的光泽反射细节，避免过度平滑导致的质感丢失；人工校验铠甲纹饰衔接断层、宝剑纹理偏差问题，参考实体佛像（或文献记载）校准色值，确保模型还原金铜材质真实视觉效果。

(1) Substantial Processing
Data Cleaning and Optimization: For models in OBJ format, combined with the features of the Growth Heavenly King—intricate armor patterns and holding a sword—conduct targeted screening and removal of redundant vertices (e.g., invalid data in the gaps between armor scales) and overlapping faces (e.g., the junction between the sword and the hand) generated during scanning. While preserving model details, reduce the data volume by 30% to improve model loading and rendering speeds, meeting the requirements for smooth operation across multiple scenarios.
Texture Mapping Adjustment: Based on the properties of gold-gilded bronze materials, accurately calibrate texture coordinates to ensure that the gilded texture of the armor and the metallic luster of the sword fit the model surface, avoiding stretching and misalignment. Adjust the texture resolution according to application scenarios: retain 4K textures for academic research to present material details, and compress to 2K for mass communication to balance visual effects and operational performance.

(2) Creative Labor
Model Refinement: Use Geomagic software to eliminate overlapping and intersecting faces, perform "mesh optimization" on armor scales and sword blades, and reduce the number of triangular faces while ensuring accurate morphology. For the force-bearing posture of the hand holding the sword, adjust joint curvature parameters to ensure a natural posture that conforms to statue-making specifications.
Surface and Texture Optimization: Apply AI adaptive filtering algorithms to process scanning noise, prioritize retaining the luster and reflection details of the gilded material to avoid texture loss caused by over-smoothing; manually verify the connection gaps of armor patterns and texture deviations of the sword, calibrate color values by referencing physical Buddha statues (or documented records) to ensure the model restores the authentic visual effect of gold-gilded bronze materials.
