章贡客家擂茶技艺“客韵擂青”数字三维立体人物模型产品

一、实质性加工 数据清洗与优化：OBJ 模型常存冗余顶点、重叠面及几何偏差，加工时将借专业软件，结合模型基础结构，排查删除无用数据。如大型复杂场景模型中，去除建模误差产生的微小重叠面，可缩减数据量、提升加载渲染速度，保障多场景流畅运行。 纹理映射调整：精准校准纹理坐标以贴合模型表面；若出现拉伸、扭曲或错位，便重新调整映射关系，同时依模型需求优化纹理质量、调节分辨率，平衡视觉效果与运行性能。 几何形态修正：修复模型几何缺陷，针对变形、不规整部分，参考原始设计意图或现实物体形态调整。 二、创造性劳动 模型数据处理：激光扫描模型输出前，用配套软件消除叠面、交叉面，减少三角面数量，同时对模型局部与整体做平滑处理，确保输出数据精准。 模型表面优化：通过 AI 智能噪波技术实现表面平滑，同步人工介入排查排除潜在错误。 纹理质量控制：针对采集的纹理照片，用后期软件消除高光、阴影及多余杂色，结合色卡照片校准色彩，获取准确均匀的模型基础颜色。Section 1: Substantive Processing 1.1 Data Cleaning and Optimization: OBJ models often contain redundant vertices, overlapping faces and geometric deviations. During processing, professional software will be adopted in combination with the basic structure of the model to identify and delete invalid data. For example, in large-scale complex scene models, removing tiny overlapping faces caused by modeling errors can reduce data volume, improve loading and rendering speed, and ensure smooth operation across multiple scenarios. 1.2 Texture Mapping Adjustment: Precisely calibrate texture coordinates to fit the model surface. If stretching, distortion or misalignment occurs, re-adjust the mapping relationship, optimize texture quality and adjust resolution according to model requirements to balance visual effects and operational performance. 1.3 Geometry Shape Correction: Repair geometric defects of the model, and adjust deformed or irregular parts by referring to the original design intent or the shape of real-world objects. Section 2: Creative Labor 2.1 Model Data Processing: Before outputting the laser-scanned model, use supporting software to eliminate overlapping and intersecting faces, reduce the number of triangular faces, and perform smoothing processing on both local and overall parts of the model to ensure the accuracy of the output data. 2.2 Model Surface Optimization: Achieve surface smoothing through AI intelligent noise technology, and conduct manual intervention simultaneously to identify and eliminate potential errors. 2.3 Texture Quality Control: For the collected texture photos, use post-processing software to remove highlights, shadows and unwanted stray colors, and calibrate colors with color card photos to obtain accurate and uniform basic colors of the model.
