void wmtk::components::TagIntersection::compute_intersection	(	Mesh &	m,
		const std::vector< std::tuple< attribute::MeshAttributeHandle, int64_t >> &	input_tags,
		const std::vector< std::tuple< attribute::MeshAttributeHandle, int64_t >> &	output_tags
	)

Parameters

m	Mesh with tags.
input_tags	A vector that contain different tag attributes and the tag value which needs to be considered.
output_tags	A vector of attibutehandles, which contains the intersection tags.

simplex_is_in_intersection()

bool wmtk::components::TagIntersection::simplex_is_in_intersection ( Mesh &  m, const simplex::Simplex &  s, const std::deque< TagAttribute > &  input_tag_attributes  )

private

Check if a given simplex is in the intersection of a given set of tag attributes.

We consider a simplex as tagged if any of its cofaces, i.e. any simplex in its open star, is tagged. If a simplex is tagged by all given attributes, it is in the intersection and the function returns true.

Parameters

m	Mesh with tags.
s	Candidate simplex for intersection check.
input_tag_attributes	Vector of tag attributes that are considered in the intersection test.
