Algorithm to remove slivers from geometries.

Parameters

geometryVector	The geometry list to be analysed
tolerance	The tolerance to be considered for detecting the slivers.

Returns

The resulting geometries

static te::vp::FeatureSet te::vp::GeometrySnapper::removeSlivers ( const te::vp::FeatureSet &  featureSet, double  tolerance, bool  discardCollapsedFeatures  )

static

Algorithm to remove slivers from features.

Parameters

vecGeometries	The geometry list to be analysed
tolerance	The tolerance to be considered for detecting the slivers.
discardCollapsedFeatures	IF TRUE, all collapsed features will be discarded from the resulting featureSet

Returns

removeSlivers() [3/3]

static te::gm::Geometry* te::vp::GeometrySnapper::removeSlivers ( te::gm::Geometry *  geometry, double  tolerance  )

static

Algorithm to remove slivers from a geometry.

Parameters

geometry	The geometry to be analysed
tolerance	The tolerance to be considered for detecting the slivers.

Returns

The resulting geometry

snapFeatures()

static te::vp::FeatureSet te::vp::GeometrySnapper::snapFeatures ( const te::vp::FeatureSet &  featureSet, double  tolerance, bool  discardCollapsedFeatures  )

static

Algorithm to snap given features to each other based on a given tolerance. This algorithm will also detect intersection segments between features and create new coordinates when necessary.

Parameters

vecGeometries	The geometry list to be analysed
tolerance	The tolerance to be considered for the snapping of the coordinates.
discardCollapsedFeatures	IF TRUE, all collapsed features will be discarded from the resulting featureSet

Returns

The resulting snapped geometries

snapGeometries() [1/2]

static te::gm::Geometry* te::vp::GeometrySnapper::snapGeometries ( const te::gm::Geometry *  geometry, double  tolerance  )

static

Algorithm to snap given geometries to each other based on a given tolerance. This algorithm will also detect intersection segments between geometries and create new coordinates when necessary.

Parameters

geometryVector	The geometry list to be analysed
tolerance	The tolerance to be considered for the snapping of the coordinates.

Returns

The resulting snapped geometries

snapGeometries() [2/2]

static te::gm::GeometryVector te::vp::GeometrySnapper::snapGeometries ( const te::gm::GeometryVectorConst &  geometryVector, double  tolerance  )

static

Algorithm to snap given geometries to each other based on a given tolerance. This algorithm will also detect intersection segments between geometries and create new coordinates when necessary.

Parameters

geometryVector	The geometry list to be analysed
tolerance	The tolerance to be considered for the snapping of the coordinates.

Returns

The resulting snapped geometries
