Methods
NameDescription
ComputeElevationAngleAboveTerrain(Cartesian, Cartesian, TerrainProvider)
Computes the elevation angle of the target object above the highest terrain between the target and an observer. The DefaultMaximumTerrainHeight is used for the computation.
ComputeElevationAngleAboveTerrain(Cartographic, Cartographic, TerrainProvider)
Computes the elevation angle of the target object above the highest terrain between the target and an observer. The DefaultMaximumTerrainHeight is used for the computation.
ComputeElevationAngleAboveTerrain(Cartesian, Cartesian, TerrainProvider, Double)
Computes the elevation angle of the target object above the highest terrain between the target and an observer.
ComputeElevationAngleAboveTerrain(Cartographic, Cartographic, TerrainProvider, Double)
Computes the elevation angle of the target object above the highest terrain between the target and an observer.
ComputeTerrainIntersection(Cartesian, UnitCartesian, Double, Double, TerrainProvider)
Computes the location of the first intersection with terrain from the provided location along the indicated direction. The DefaultMaximumTerrainHeight is used for the computation.
ComputeTerrainIntersection(Cartographic, UnitCartesian, Double, Double, TerrainProvider)
Computes the location of the first intersection with terrain from the provided location along the indicated direction. The DefaultMaximumTerrainHeight is used for the computation.
ComputeTerrainIntersection(Cartesian, Cartographic, UnitCartesian, Double, Double, TerrainProvider)
Computes the location of the first intersection with terrain from the provided location along the indicated direction. Both Cartesian and Cartographic representations of the location are provided which eliminates the need for conversion within the algorithm and results in greater efficiency. The DefaultMaximumTerrainHeight is used for the computation.
ComputeTerrainIntersection(Cartesian, UnitCartesian, Double, Double, TerrainProvider, Double)
Computes the location of the first intersection with terrain from the provided location along the indicated direction.
ComputeTerrainIntersection(Cartographic, UnitCartesian, Double, Double, TerrainProvider, Double)
Computes the location of the first intersection with terrain from the provided location along the indicated direction.
ComputeTerrainIntersection(Cartesian, Cartographic, UnitCartesian, Double, Double, TerrainProvider, Double)
Computes the location of the first intersection with terrain from the provided location along the indicated direction. Both Cartesian and Cartographic representations of the location are provided which eliminates the need for conversion within the algorithm and results in greater efficiency.
