Geometric reconstruction from point-normal data
Extrusions and intrusions are special cases of elaboration.
Geometric reconstruction from point-normal data
The reconstruction results related to elaboration focus on reconstruction of polyhedra that can be obtained by elaborating a convex polyhedra with extrusions and intrusions of convex polygons.
Geometric reconstruction from point-normal data
By including additional ordering information in the metadata, extrusions and intrusions from nonconvex polygons can also be handled.
Geometric reconstruction from point-normal data
Let P be a set of polyhedra obtained from a set of convex polyhedron by intrusions and extrusions, where al l of the intrusions and extrusions in each face are non-intersecting, orthogonal rectangular intrusions.
