Detailed Description

Creates a TIN using the Weighted Locally Optimal Projection (WLOP) algorithm.

We use the implementation of WLOP on the CGAL libraries, which are based on the following paper:
H. Huang, D. Li, H. Zhang, U. Ascher, and D. Cohen-Or. Consolidation of unorganized point clouds for surface reconstruction. ACM Transactions on Graphics, 28:176:1–176:78, 2009.

Constructor & Destructor Documentation

TinCreationSimplificationPointSetWLOP() [1/2]

TinCreation::TinCreationSimplificationPointSetWLOP::TinCreationSimplificationPointSetWLOP ( double  borderSimplificationMaxDistance, double  borderSimplificationMaxLength, unsigned int  minFeaturePolylineSize, double  retainPercentage, double  radius, unsigned int  iterNumber = 35  )

inline

Constructor

Parameters

borderSimplificationMaxDistance	Maximum error for polyline simplification
borderSimplificationMaxLengthPercent	Maximum length for an edge in the simplified polyline. This prevents oversimplification in planar tiles.
minFeaturePolylineSize	Minimum number of connected edges in a sharp feature polyline to consider it during processing
retainPercentage	Percentage of points to retain
radius	Spherical neighborhood radius
iterNumber	Number of iterations to solve the optimization problem

TinCreationSimplificationPointSetWLOP() [2/2]

TinCreation::TinCreationSimplificationPointSetWLOP::TinCreationSimplificationPointSetWLOP ( std::vector< double >  borderSimplificationMaxDistancePerZoom, std::vector< double >  borderSimplificationMaxLengthPerZoom, unsigned int  minFeaturePolylineSize, std::vector< double >  retainPercentagePerZoom, std::vector< double >  radiusPerZoom, unsigned int  iterNumber = 35  )

inline

Constructor

Parameters

borderSimplificationMaxDistance	Maximum error for polyline simplification per zoom
borderSimplificationMaxLengthPercent	Maximum length for an edge in the simplified polyline per zoom. This prevents oversimplification in planar tiles.
minFeaturePolylineSize	Minimum number of connected edges in a sharp feature polyline to consider it during processing
retainPercentage	Percentage of points to retain per zoom
radius	Spherical neighborhood radius per zoom
iterNumber	Number of iterations to solve the optimization problem per zoom
