Detailed Description

identify and fill holes in meshes

vtkFillHolesFilter is a filter that identifies and fills holes in input vtkPolyData meshes. Holes are identified by locating boundary edges, linking them together into loops, and then triangulating the resulting loops. Note that you can specify an approximate limit to the size of the hole that can be filled.

Warning:

Note that any mesh with boundary edges by definition has a topological hole. This even includes a reactangular grid (e.g., the output of vtkPlaneSource). In such situations, if the outer hole is filled, retriangulation of the hole will cause geometric overlap of the mesh. This can be prevented by using the hole size instance variable to prevent the larger holes from being triangulated.

Note this filter only operates on polygons and triangle strips. Vertices and polylines are passed through untouched.

Specify the maximum hole size to fill. This is represented as a radius to the bounding circumsphere containing the hole. Note that this is an approximate area; the actual area cannot be computed without first triangulating the hole.
