Member Function Documentation

◆ Clear()

TetraMesh & open3d::geometry::TetraMesh::Clear ( )

overridevirtual

Clear all elements in the geometry.

Reimplemented from open3d::geometry::MeshBase.

◆ CreateFromPointCloud()

std::tuple< std::shared_ptr< TetraMesh >, std::vector< size_t > > open3d::geometry::TetraMesh::CreateFromPointCloud ( const PointCloud & point_cloud )

static

Function that creates a tetrahedral mesh (TetraMeshFactory.cpp). from a point cloud. The method creates the Delaunay triangulation using the implementation from Qhull.

◆ ExtractTriangleMesh()

std::shared_ptr< TriangleMesh > open3d::geometry::TetraMesh::ExtractTriangleMesh	(	const std::vector< double > &	values,
		double	level
	)

Function to extract a triangle mesh of the specified iso-surface at

Parameters

values	are values per-vertex. This method applies primal contouring and generates triangles for each tetrahedron.

◆ HasTetras()

bool open3d::geometry::TetraMesh::HasTetras ( ) const

inline

◆ operator+()

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

◆ operator+=()

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

◆ RemoveDegenerateTetras()

TetraMesh & open3d::geometry::TetraMesh::RemoveDegenerateTetras ( )

Function that removes degenerate tetrahedra, i.e., tetrahedra that reference a single vertex multiple times in a single tetrahedron. They are usually the product of removing duplicated vertices.

◆ RemoveDuplicatedTetras()

TetraMesh & open3d::geometry::TetraMesh::RemoveDuplicatedTetras ( )

Function that removes duplicated tetrahedra, i.e., removes tetrahedra that reference the same four vertices, independent of their order.

◆ RemoveDuplicatedVertices()

TetraMesh & open3d::geometry::TetraMesh::RemoveDuplicatedVertices ( )

Function that removes duplicated verties, i.e., vertices that have identical coordinates.

◆ RemoveUnreferencedVertices()

TetraMesh & open3d::geometry::TetraMesh::RemoveUnreferencedVertices ( )

This function removes vertices from the tetra mesh that are not referenced in any tetrahedron of the mesh.
