1. Substantive Processing Data Cleaning and Optimization: OBJ models often suffer from redundant vertices, overlapping faces, and geometric deviations. During processing, professional software will be employed to identify and delete invalid data by leveraging the basic structure of the model. For instance, in large and complex scene models, removing tiny overlapping faces generated by modeling errors can reduce data volume, improve loading and rendering speed, and ensure smooth operation across multiple scenarios. Texture Mapping Adjustment: Precisely calibrate texture coordinates to fit the model surface; if stretching, distortion or misalignment occurs, the mapping relationship will be readjusted. Meanwhile, optimize texture quality and adjust resolution according to model requirements to balance visual effects and operational performance. Geometric Shape Correction: Repair geometric defects of the model, and adjust deformed or irregular parts by referring to the original design intent or the morphology of real-world objects. 2. Creative Labor Model Data Processing: Before outputting laser-scanned models, 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 accurate output data. Model Surface Optimization: Achieve surface smoothing through AI Agent noise technology, while manually intervening to identify and eliminate potential errors. Texture Quality Control: For collected texture photos, use post-processing software to remove highlights, shadows and redundant color artifacts, and calibrate colors with color card photos to obtain accurate and uniform basic colors of the model.
