Member Function Documentation

FaceHandle OpenMesh::TriConnectivity::add_face	(	VertexHandle	_vh0,
		VertexHandle	_vh1,
		VertexHandle	_vh2
	)			[inline]

Override OpenMesh::Mesh::PolyMeshT::add_face().

Faces that aren't triangles will be triangulated and added. In this case an invalid face handle will be returned.

Reimplemented from OpenMesh::PolyConnectivity.

TriConnectivity::FaceHandle OpenMesh::TriConnectivity::add_face	(	const VertexHandle *	_vhandles,
		uint	_vhs_size
	)

Add a new vertex.

face is triangle -> ok

face is not a triangle -> triangulate

Reimplemented from OpenMesh::PolyConnectivity.

FaceHandle OpenMesh::TriConnectivity::add_face

(

const std::vector< VertexHandle > &

_vhandles

)

[inline]

Override OpenMesh::Mesh::PolyMeshT::add_face().

Faces that aren't triangles will be triangulated and added. In this case an invalid face handle will be returned.

Reimplemented from OpenMesh::PolyConnectivity.

void OpenMesh::TriConnectivity::assign_connectivity

(

const PolyConnectivity &

_other

)

[inline]

assign_connectivity() method.

See ArrayKernel::assign_connectivity() for more details.

Reimplemented from OpenMesh::PolyConnectivity.

void OpenMesh::TriConnectivity::assign_connectivity

(

const TriConnectivity &

_other

)

[inline]

assign_connectivity() methods.

See ArrayKernel::assign_connectivity() for more details. When the source connectivity is not triangles, in addition "fan" connectivity triangulation is performed

void OpenMesh::TriConnectivity::flip

(

EdgeHandle

_eh

)

Flip edge _eh.

Check for topological correctness first using is_flip_ok().

bool OpenMesh::TriConnectivity::is_collapse_ok

(

HalfedgeHandle

_heh

)

Returns whether collapsing halfedge _heh is ok or would lead to topological inconsistencies.

Attention:

This method need the Attributes::Status attribute and changes the tagged bit.
