Detailed Description

Parameters for Poisson reconstruction.

Public Attributes
int	depth
	Maximum depth of the tree that will be used for surface reconstruction.
int	kernelDepth
int	iters
	Specifies the number of Gauss-Seidel relaxations to be performed at each level of the octree hierarchy.
int	boundaryType
	Boundary type for the finite elements. Valid values are: 0 : Free boundary constraints; -1 : Dirichlet boundary constraints; 1 : Neumann boundary constraints.
float	samplesPerNode
	This floating point value specifies the minimum number of sample points that should fall within an octree node as the octree construction is adapted to sampling density.
float	scale
	Specifies the ratio between the diameter of the cube used for reconstruction and the diameter of the samples' bounding cube.
float	solverAccuracy
	CG solver accuracy.
float	pointWeight
	Specifies the importance that interpolation of the point samples is given in the formulation of the screened Poisson equation.
bool	showResidual
float	confidence
	Specifies the exponent to be applied to a point's confidence to adjust its weight. (A point's confidence is defined by the magnitude of its normal.)
bool	density
	Enabling this flag tells the reconstructor to output the estimated depth values of the iso-surface vertices.
bool	verbose
	Enabling this flag provides a more verbose description of the running times and memory usages of individual components of the surface reconstructor.
float	width
	Specifies the target width of the finest level octree cells. This parameter is ignored if the 'depth' is also specified (greater or equal to 0)
bool	inCore
float	confidenceBias
	Specifies the exponent to be applied to a point's confidence to bias the resolution at which the sample contributes to the linear system. (Points with lower confidence are biased to contribute at coarser resolutions.)
float	dataX
	Pull factor.
bool	colors
	Enabling this flag tells the reconstructor to read in color values with the input points and extrapolate those to the vertices of the output.
bool	normals
	Enabling this flag tells the reconstructor to output vertex normals, computed from the gradients of the implicit function.
bool	exactInterpolation
int	baseDepth
	Coarse MG solver depth.
int	fullDepth
int	baseVCycles
	Coarse MG solver V-cycles.
bool	linearFit
	Enabling this flag has the reconstructor use linear interpolation to estimate the positions of iso - vertices.
int	degree
	Degree of the B-spline that is to be used to define the finite elements system. Larger degrees support higher order approximations, but come at the cost of denser system matrices (incurring a cost in both space and time).
int	maxMemoryGB
	If positive, this integer value specifies the peak memory utilization for running the reconstruction code (forcing the execution to terminate if the limit is exceeded)
DensityThresholdMode	densityThresholdMode
	Mode of thresholding.
float	densityThreshold
	Density threshold for selected thresholding mode.
bool	useDensityToColor
	Use mapping of density information to replace colors.

Member Data Documentation

depth

int 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 ... Note that since the reconstructor adapts the octree to the sampling density, the specified reconstruction depth is only an upper bound

samplesPerNode

float samplesPerNode

This floating point value specifies the minimum number of sample points that should fall within an octree node as the octree construction is adapted to sampling density.

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.

pointWeight

float pointWeight

Specifies 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
