Extract external faces of a geometry.
ExternalFaces
is a filter that extracts all external faces from a data set. An external face is defined is defined as a face/side of a cell that belongs only to one cell in the entire mesh.
vtkm::filter::entity_extraction::ExternalFaces::ExternalFaces | ( | ) |
|
override |
|
inlineoverridevirtual |
Returns whether the filter can execute on partitions in concurrent threads.
If a derived class's implementation of DoExecute
cannot run on multiple threads, then the derived class should override this method to return false.
Reimplemented from vtkm::filter::Filter.
|
overrideprivatevirtual |
Implements vtkm::filter::Filter.
|
private |
|
inline |
Option to remove unused points and compact result int a smaller array.
When CompactPoints is on, instead of copying the points and point fields from the input, the filter will create new compact fields without the unused elements. When off (the default), unused points will remain listed in the topology, but point fields and coordinate systems will be shallow-copied to the output.
|
inline |
Specify how polygonal data (polygons, lines, and vertices) will be handled.
When on (the default), these cells will be passed to the output. When off, these cells will be removed from the output. (Because they have less than 3 topological dimensions, they are not considered to have any "faces.")
