◆ CreateFromPointCloudBallPivoting()

std::shared_ptr< ccMesh > ccMesh::CreateFromPointCloudBallPivoting	(	const ccPointCloud &	pcd,
		const std::vector< double > &	radii
	)

static

Function that computes a triangle mesh from a oriented PointCloud

Parameters

pcd.	This implements the Ball Pivoting algorithm proposed in F. Bernardini et al., "The ball-pivoting algorithm for surface reconstruction", 1999. The implementation is also based on the algorithms outlined in Digne, "An Analysis and Implementation of a Parallel Ball Pivoting Algorithm", 2014. The surface reconstruction is done by rolling a ball with a given radius (cf.
radii)	over the point cloud, whenever the ball touches three points a triangle is created.
pcd	defines the PointCloud from which the ccMesh surface is reconstructed. Has to contain normals.
radii	defines the radii of the ball that are used for the surface reconstruction.

		float	point_weight = `2.f`,
		float	samples_per_node = `1.5f`,
		int	boundary_type = `2`,
		int	n_threads = `-1`
	)

static

Function that computes a triangle mesh from a oriented PointCloud pcd. This implements the Screened Poisson Reconstruction proposed in Kazhdan and Hoppe, "Screened Poisson Surface Reconstruction", 2013. This function uses the original implementation by Kazhdan. See https://github.com/mkazhdan/PoissonRecon.

Parameters

pcd	PointCloud with normals and optionally colors.
depth	Maximum depth of the tree that will be used for surface reconstruction. Running at depth d corresponds to solving on a grid whose resolution is no larger than 2^d x 2^d x 2^d. Note that since the reconstructor adapts the octree to the sampling density, the specified reconstruction depth is only an upper bound.
width	Specifies the target width of the finest level octree cells. This parameter is ignored if depth is specified.
scale	Specifies the ratio between the diameter of the cube used for reconstruction and the diameter of the samples' bounding cube.
linear_fit	If true, the reconstructor use linear interpolation to estimate the positions of iso-vertices.
point_weight	The importance that interpolation of the point samples is given in the formulation of the screened Poisson equation. The results of the original (unscreened) Poisson Reconstruction can be obtained by setting this value to 0
samples_per_node	The minimum number of sample points that should fall within an octree node as the octree construction is adapted to sampling density. This parameter specifies the minimum number of points that should fall within an octree node. For noise-free samples, small values in the range [1.0 - 5.0] can be used. For more noisy samples, larger values in the range [15.0 - 20.0] may be needed to provide a smoother, noise-reduced, reconstruction.
boundary_type	Boundary type for the finite elements
n_threads	Number of threads used for reconstruction. Set to -1 to automatically determine it.

Returns: The estimated ccMesh, and per vertex densitie values that can be used to to trim the mesh.

ccMesh * ccMesh::createNewMeshFromSelection	(	bool	removeSelectedTriangles,

Creates a new mesh with the selected vertices only.

This method is called after a graphical segmentation. It creates a new mesh structure with the vertices that are tagged as "visible" (see ccGenericPointCloud::visibilityArray). This method will also update this mesh if removeSelectedFaces is true. In this case, all "selected" triangles will be removed from this mesh's instance.

    \param  removeSelectedTriangles         specifies if the

faces composed only of 'selected' vertices should be removed or not. If true, the visibility array will be automatically unallocated on completion

Parameters

newIndexesOfRemainingTriangles	the new indexes of the remaining triangles (if removeSelectedTriangles is true - optional). Must be initially empty or have the same size as the original mesh.
withChildEntities	whether child entities should be transferred as well (see ccHObjectCaster::CloneChildren)

Returns: the new mesh (if successful) or itself if all vertices were visible/selected
