One advantage of the disclosed repair engine and associated hole repair technique is that the mesh repair engine is capable of generating polygons that fill regions of a 3D model that are not defined. Consequently, an end-user of the mesh repair tool is able to generate watertight 3D models from previously incomplete and non-watertight 3D models."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Technique for filling holes in a three-dimensional model","description":"A mesh repair engine is configured to repair a hole in a three-dimensional (3D) model by (i) filling the hole with a rough mesh, (ii) refining the rough mesh, (iii) collapsing the refined mesh, (iv) r","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9747721","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
