Select cut edges

[czc98]

Hi, How to implement 'select cut edges' in Boolean functions in C++?

[Grantim]

You can use parameters overload of boolean function with outCutEdges option:

MeshLib/source/MRMesh/MRMeshBoolean.h

Lines 92 to 93 in c2c4c36

	/// Optional output cut edges of booleaned meshes
	std::vector<EdgeLoop>* outCutEdges = nullptr;

MeshLib/source/MRMesh/MRMeshBoolean.h

Lines 107 to 108 in c2c4c36

	MRMESH_API BooleanResult boolean( const Mesh& meshA, const Mesh& meshB, BooleanOperation operation,
	const BooleanParameters& params = {} );

Is there a simple way to convert outCutEdges to UndirectedEdgeBitSet?

[Grantim]

Seems that there is no single function, but code should be simlpe

UndirectedEdgeBitSet cutEdgesBitSet;
for( const auto& cutPath : *outCutEdges )
    for( auto e : cutPath )
        cutEdgesBitSet.autoResizeSet( e.undircted() );
