Member Function Documentation

◆ BoundaryHalfEdgesFromVertex()

std::vector< int > open3d::geometry::HalfEdgeTriangleMesh::BoundaryHalfEdgesFromVertex ( int vertex_index ) const

Query manifold boundary half edges from a starting vertex If query vertex is not on boundary, empty vector will be returned

◆ BoundaryVerticesFromVertex()

std::vector< int > open3d::geometry::HalfEdgeTriangleMesh::BoundaryVerticesFromVertex ( int vertex_index ) const

Query manifold boundary vertices from a starting vertex If query vertex is not on boundary, empty vector will be returned

◆ Clear()

void open3d::geometry::HalfEdgeTriangleMesh::Clear ( )

overridevirtual

Clear all data in HalfEdgeTriangleMesh.

Implements open3d::geometry::Geometry3D.

◆ ComputeHalfEdges()

bool open3d::geometry::HalfEdgeTriangleMesh::ComputeHalfEdges ( )

Compute and update half edges, half edge can only be computed if the mesh is a manifold. Returns true if half edges are computed.

◆ GetBoundaries()

std::vector< std::vector< int > > open3d::geometry::HalfEdgeTriangleMesh::GetBoundaries ( ) const

Returns a vector of boundaries. A boundary is a vector of vertices.

◆ HasHalfEdges()

bool open3d::geometry::HalfEdgeTriangleMesh::HasHalfEdges ( ) const

True if half-edges have already been computed.

◆ NextHalfEdgeFromVertex()

int open3d::geometry::HalfEdgeTriangleMesh::NextHalfEdgeFromVertex ( int init_half_edge_index ) const

protected

Returns the next half edge from starting vertex of the input half edge, in a counterclock wise manner. Returns -1 if when hitting a boundary. This is done by traversing to the next, next and twin half edge.

◆ NextHalfEdgeOnBoundary()

int open3d::geometry::HalfEdgeTriangleMesh::NextHalfEdgeOnBoundary ( int curr_half_edge_index ) const

protected

◆ operator+()

HalfEdgeTriangleMesh open3d::geometry::HalfEdgeTriangleMesh::operator+ ( const HalfEdgeTriangleMesh & mesh ) const

◆ operator+=()

HalfEdgeTriangleMesh & open3d::geometry::HalfEdgeTriangleMesh::operator+= ( const HalfEdgeTriangleMesh & mesh )

◆ RemoveDuplicatedTriangles()

void open3d::geometry::HalfEdgeTriangleMesh::RemoveDuplicatedTriangles ( )

overrideprotectedvirtual

Reimplemented from open3d::geometry::TriangleMesh.

◆ RemoveDuplicatedVertices()

void open3d::geometry::HalfEdgeTriangleMesh::RemoveDuplicatedVertices ( )

overrideprotectedvirtual

Reimplemented from open3d::geometry::TriangleMesh.

◆ RemoveNonManifoldTriangles()

void open3d::geometry::HalfEdgeTriangleMesh::RemoveNonManifoldTriangles ( )

overrideprotectedvirtual

Reimplemented from open3d::geometry::TriangleMesh.

◆ RemoveNonManifoldVertices()

void open3d::geometry::HalfEdgeTriangleMesh::RemoveNonManifoldVertices ( )

overrideprotectedvirtual

Reimplemented from open3d::geometry::TriangleMesh.

◆ ordered_half_edge_from_vertex_

std::vector<std::vector<int> > open3d::geometry::HalfEdgeTriangleMesh::ordered_half_edge_from_vertex_

Counter-clockwise ordered half-edges started from each vertex If the vertex is on boundary, the starting edge must be on boundary too
