Member Function Documentation

◆ Clear()

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

overridevirtual

Implements open3d::geometry::Geometry3D.

◆ CreateFromPointCloud()

std::shared_ptr< TetraMesh > 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

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.

◆ Rotate()

TetraMesh & open3d::geometry::TetraMesh::Rotate	(	const Eigen::Vector3d &	rotation,
