Detailed Description

HalfEdge class contains vertex, triangle info about a half edge, as well as relations of next and twin half edge.

Constructor & Destructor Documentation

HalfEdge() [1/2]

open3d::geometry::HalfEdgeTriangleMesh::HalfEdge::HalfEdge ( )

inline

Default Constructor.

Initializes all members of the instance with invalid values.

HalfEdge() [2/2]

open3d::geometry::HalfEdgeTriangleMesh::HalfEdge::HalfEdge	(	const Eigen::Vector2i &	vertex_indices,
		int	triangle_index,
		int	next,
		int	twin )

Member Function Documentation

IsBoundary()

bool open3d::geometry::HalfEdgeTriangleMesh::HalfEdge::IsBoundary ( ) const

inline

Returns true iff the half edge is the boundary (has not twin, i.e. twin index == -1).

Field Documentation

next_

int open3d::geometry::HalfEdgeTriangleMesh::HalfEdge::next_

Index of the next HalfEdge in the same triangle.

triangle_index_

int open3d::geometry::HalfEdgeTriangleMesh::HalfEdge::triangle_index_

Index of the triangle containing this half edge.

twin_

int open3d::geometry::HalfEdgeTriangleMesh::HalfEdge::twin_

Index of the twin HalfEdge.

vertex_indices_

Eigen::Vector2i open3d::geometry::HalfEdgeTriangleMesh::HalfEdge::vertex_indices_

Index of the ordered vertices forming this half edge.
