Spatial decomposition-based repair of defects in boundary representations
A computing system may include a mesh access engine and a mesh repair engine. The mesh access engine may be configured to access a boundary representation of an object design, the boundary representation including a defect. The mesh repair engine may be configured to repair the boundary representation, including by converting the boundary representation into a spatial decomposition representation of the object design and converting the spatial decomposition representation of the object design back into a boundary representation form to obtain a repaired boundary representation of the object design.
1. A method comprising:
by a computing system:
accessing a boundary representation of an object design, the boundary representation including a defect; and
repairing the boundary representation without determining a location of the defect in the boundary representation, including by:
converting the boundary representation into a spatial decomposition representation of the object design; and
converting the spatial decomposition representation of the object design back into a boundary representation form to obtain a repaired boundary representation of the object design.
2. The method of claim 1 , comprising repairing the boundary representation without expressly identifying the defect in the boundary representation.
3. The method of claim 1 , wherein the defect comprises a slit defect with size smaller than a mesh resolution of the boundary representation, an inconsistently oriented facet, a non-manifold facet, overlapping facets, or any combination thereof.
4. The method of claim 3 , comprising removing the defect from the object design through the converting of the boundary representation into the spatial decomposition representation.
5. The method of claim 1 , wherein the boundary representation and the repaired boundary representation have different mesh facet layouts.
6. The method of claim 1 , comprising converting the spatial decomposition representation of the object design into the repaired boundary representation at a different mesh resolution from the boundary representation.
7. A system comprising:
a mesh access engine configured to access a boundary representation of an object design, the boundary representation including a defect; and
a mesh repair engine configured to repair the boundary representation without determining a location of the defect in the boundary representation, including by:

access a boundary representation of an object design, the boundary representation including a defect; and
repair the boundary representation without determining a location of the defect in the boundary representation, including by:
converting the boundary representation into a spatial decomposition representation of the object design; and
converting the spatial decomposition representation of the object design back into a boundary representation form to obtain a repaired boundary representation of the object design.
