Substantive Processing 1. Data Cleaning and Optimization: OBJ models often suffer from redundant vertices, overlapping faces and geometric information errors. During processing, professional software will be utilized to identify and remove redundant data by leveraging the fundamental structural characteristics of the model. For example, in large and complex scene models, eliminating tiny overlapping faces induced by modeling errors can reduce data volume, improve loading and rendering speed, and ensure smooth operation across various scenarios. 2. Texture Mapping Adjustment: Precisely calibrate texture coordinates to ensure proper fitting of textures to the model surface. If stretching, distortion or misalignment occurs, the mapping configuration will be readjusted; meanwhile, optimize texture quality and adjust resolution according to model requirements to strike a balance between visual fidelity and operational performance. 3. Geometric Shape Correction: Repair geometric defects of the model, and adjust deformed or irregular components by referring to the original design intent or the physical morphology of real-world objects. Creative Labor 1. Model Data Processing: Prior to outputting the laser-fabricated model, supporting software will be employed to remove overlapping and intersecting faces, reduce the count of triangular faces, and conduct smoothing operations on both local and global parts to ensure the accuracy of the exported data. 2. Model Surface Optimization: Utilize AI Agent-driven noise smoothing to refine the model surface, while performing manual inspections to identify and eliminate potential errors. 3. Texture Quality Control: For collected texture photographs, post-processing software will be used to eliminate highlights, shadows and extraneous blemishes, and perform color calibration using color chart photos to obtain accurate and uniform base colors for the model.
