“A new breakthrough has emerged in the technology industry, with experts proposing a feature preserving hybrid folding algorithm for simplifying triangular mesh models in additive manufacturing and reverse engineering. This algorithm accurately calculates the curvature of new vertices, efficiently calculates the folding cost, and uses edge folding for feature regions and triangle folding for non feature regions to achieve efficient simplification. The simplified model maintains good details and features, with minimal deformation and moderate efficiency, providing a new and effective means for grid model processing.”
