noether::ExtrudedPolygonSubsetExtractor Struct Reference

Extracts the submesh with the vertices captured inside an extruded polygon defined by the input boundary points. More...

Detailed Description

Operations

• Fit plane to boundary points
• Project boundary points onto fitted plane
• Extrude a prism defined by the projected boundary to the extents of the mesh in the direction of the fitted plane normal
• Identify the vertices within the extruded prism
• Cluster the inlier vertices
• Extract the single cluster of vertices whose centroid is closest to the centroid of the boundary
