LuciadFusionClass TLcdTransformedHeightProvider

java.lang.Object

com.luciad.util.height.TLcdTransformedHeightProvider

All Implemented Interfaces:

ILcdBounded, ILcdHeightProvider

public class TLcdTransformedHeightProvider
extends Object
implements ILcdHeightProvider

This height provider retrieves its heights from another height provider with a different reference.

Since:

9.1

Constructor Summary

Constructor and Description
TLcdTransformedHeightProvider(ILcdHeightProvider aHeightProvider, ILcdModelModelTransformation aTransformation) Creates a new TLcdTransformedHeightProvider that uses the given transformation to transform between the reference in which points are given (the destination reference) and the reference associated with the given delegate height provider (the source reference).

Method Summary

Modifier and Type	Method and Description
ILcdBounds	getBounds() Returns the ILcdBounds by which the geometry of this ILcdBounded object is bounded.
double	retrieveHeightAt(ILcdPoint aPoint) Returns the height at the given point.

Constructor Detail

TLcdTransformedHeightProvider

public TLcdTransformedHeightProvider(ILcdHeightProvider aHeightProvider,
                                     ILcdModelModelTransformation aTransformation)
                              throws TLcdNoBoundsException

Creates a new TLcdTransformedHeightProvider that uses the given transformation to transform between the reference in which points are given (the destination reference) and the reference associated with the given delegate height provider (the source reference).

Parameters:

aHeightProvider - the height provider from which heights will be retrieved.

aTransformation - the transformation that will be applied to each point for which a height is retrieved (destination -> source reference), and to each height, after it has been retrieved (source -> destination reference). Note that the transformation should be initialized, i.e. the source and target references must be set.

Throws:

TLcdNoBoundsException - if the transformed height provider doesn't have valid bounds.

Method Detail

retrieveHeightAt

public double retrieveHeightAt(ILcdPoint aPoint)

Description copied from interface: ILcdHeightProvider

Returns the height at the given point.

Specified by:

retrieveHeightAt in interface ILcdHeightProvider

Parameters:

aPoint - a 2D point, in the horizontal reference that is determined by the implementation.

Returns:

the elevation at the given point, in the vertical reference that is determined by the implementation. The value may also be Double.NaN, if the elevation is not known.

getBounds

public ILcdBounds getBounds()

Description copied from interface: ILcdBounded

Returns the ILcdBounds by which the geometry of this ILcdBounded object is bounded.

If the geometry does not allow retrieving valid bounds (for example a polyline with 0 points) the return value is unspecified. It is highly recommended to return an undefined bounds. You can create undefined bounds using the default constructors of TLcdLonLatBounds or TLcdXYBounds.

Specified by:

getBounds in interface ILcdBounded

Returns:

the ILcdBounds by which the geometry of this ILcdBounded object is bounded.
