Constructor & Destructor Documentation

IG.Num.PointCloudSampledDataElement.PointCloudSampledDataElement ( )

inline

Constructs a cloud of ponts where points are of vector type.

IG.Num.PointCloudSampledDataElement.PointCloudSampledDataElement ( params SampledDataElement[] points )

inline

Constructs a cloud of vector points containing the specified points.

Parameters

points Points that are included in the created point cloud.

IG.Num.PointCloudSampledDataElement.PointCloudSampledDataElement ( params IPointContainer< SampledDataElement >[] points )

inline

Constructs a cloud of vector points containing the points embedded in the specified point containers.

All points are taken from their point containers and embedded in newly created point containers before adding to the created cloud of points.

Parameters

points Points embedded in point containers that are included in the created point cloud.

Member Function Documentation

override SampledDataElement IG.Num.PointCloudSampledDataElement.CreatePointFromCoordinates ( IVector coordinates )

inlinevirtual

Creates and returns a new point with specified coordinates.

For this method to work, the delegate CreateOutputValues must be defined, which creates the output values correspoinding to specific input parameters.

Parameters

coordinates Coordinates of the created point. A copy of this vector should always be created to hold coordinates within the point, because the caller is allowed to modify coordinates on the vector.

Implements IG.Num.PointCloud< PointLinkType, PointContainerType, PointType >.

delegate IVector IG.Num.PointCloudSampledDataElement.CreateOutputValuesDelegate ( IVector inputParameters )

This delegate is used to create output values for a newly created training elements from the specified input parameters.

This delegate is used in the CreateOutputValues property of its containing class.

Parameters

inputParameters Input parameters of the neural training element.

Returns: The generated output values corresponding to the specified input parameters.

override PointContainerSampledDataElement IG.Num.PointCloudSampledDataElement.CreatePointContainer ( SampledDataElement point )

inline

Creates and returns a new point container that wraps the specified point.

Parameters

point Point to be wrapped.

override DistanceComparer<PointContainerSampledDataElement, SampledDataElement> IG.Num.PointCloudSampledDataElement.CreateDefaultDistanceComparer ( PointContainerSampledDataElement referencePoint )

inline

Creates and returnws a distance comparer of hte default type for the current type of point of clouds.
