\section PMPOrientation Orientation
|
||||
|
||||
This package provides functions dealing with the orientation of faces in a closed polygon mesh.
|
||||
|
||||
The function `CGAL::Polygon_mesh_processing::is_outward_oriented()` checks whether
|
||||
the polygon mesh is oriented such that the normals to faces are oriented towards the
|
||||
outside of the domain bounded by the input polygon mesh.
|
||||
|
||||
In case the orientation is not satisfactory to the user, the function
|
||||
`CGAL::Polygon_mesh_processing::reverse_face_orientations()` reverses the orientation
|
||||
of halfedges around faces, and consequently of normals associated to faces.
|
||||
|
||||
See \ref PolygonSoupExample for an example of how these functions can be used.
