ITerrainThreatDome81

Terrain threat dome objects are 3D shapes, resembling the top half of a sphere, used to analyze and display the volume that is visible from a given point on the terrain. Any point inside the threat dome can be viewed from the dome’s pivot point. Using the interface’s properties, you can set various parameters, like the range and elevation angle, and analyze different areas for visibility.

	Properties
	Action	An IAction81 representing the operation that takes place when the object is clicked in the Project Tree.
	AngularStep	Gets the space between each sampling ray.
	Color	An IColor81 representing the threat dome color.
	Direction	Gets the center direction of the scan.
	ElevationAngle	Gets the angle, from the ground, below which any point inside the threat dome cannot be viewed from the pivot point.
	HorizontalEndAngle	Gets the ending horizontal angle of the scan.
	HorizontalFOV	Gets the value in degrees, representing the scan field of the threat dome.
	HorizontalStartAngle	Gets the starting horizontal angle of the scan.

	Position	An IPosition81 representing the threat dome pivot point’s position.
	RadialStep	Gets the distance between sample points along each ray.
	Range	Gets the radius of the scan
	SaveInFlyFile	Gets and sets a Boolean that determines whether the threat dome is saved in the Fly file. (Inherited from ITerraExplorerObject81)
	Terrain	An ITerrainObject81 representing terrain properties including draw order and ground object status.
	TimeSpan	An ITimeSpan81 representing the timespan in which the threat dome is visible on the terrain.
	Tooltip	An ITooltip81 representing the tooltip that displays when a mouse cursor is placed over the object in the 3D Window.
	TreeItem	An ITreeItem81 describing the representation of the threat dome in the Project Tree.
	Visibility	An IVisibility81 representing the visibility of the threat dome at different distances.
	Methods

	SetClientData	Sets an array of text strings assigned to each object global namespace. (Inherited from ITerraExplorerObject81)
	SetParam	Reserved. Currently not used. (Inherited from ITerraExplorerObject81)

AngularStep

Gets the space between each sampling ray. The smaller the ray spacing, the more accurate the measurement, but the longer it takes to calculate.

JavaScript
AngularStep

C#
double AngularStep { get; }

C++
HRESULT AngularStep([out, retval] double* pVal)

Direction

Gets the center direction of the scan.

JavaScript
Direction

C#
double Direction { get; }

C++
HRESULT Direction([out, retval] double* pVal)

ElevationAngle

Gets the angle, from the ground, below which any point inside the threat dome cannot be viewed from the pivot point. For example, an elevation angle of zero creates a complete half sphere, while an angle of 30 degrees creates an inverted cone, topped by a section of a sphere.

JavaScript
ElevationAngle

C#
double ElevationAngle { get; }

C++
HRESULT ElevationAngle([out, retval] double* pVal)

HorizontalEndAngle

Gets the ending horizontal angle of the scan.

JavaScript
HorizontalEndAngle

C#
double HorizontalEndAngle { get; }

C++
HRESULT HorizontalEndAngle([out, retval] double* pVal)

HorizontalFOV

Gets the value in degrees, representing the scan field of the threat dome.

JavaScript
HorizontalFOV

C#
double HorizontalFOV { get; }

C++
HRESULT HorizontalFOV([out, retval] double* pVal)

HorizontalStartAngle

Gets the starting horizontal angle of the scan.

JavaScript
HorizontalStartAngle

C#
double HorizontalStartAngle { get; }

C++
HorizontalStartAngle([out, retval] double* pVal)

RadialStep

Gets the distance between sample points along each ray. The smaller the sample interval, the more accurate the measurement, but the longer it takes to calculate.

JavaScript
RadialStep

C#
double RadialStep { get; }

C++
HRESULT RadialStep([out, retval] double* pVal)

Range

Gets the radius of the scan.

JavaScript
Range

C#
double Range { get; }

C++
HRESULT Range([out, retval] double* pVal)
