I3DViewshed80
This interface provides properties and methods for calculating and creating a graphical representation of the area on the terrain and on 3D models and objects that is visible from a specified position.
|
Properties |
|
|
An IAction80 representing the operation that takes place when the viewshed is clicked in the Project Tree. |
|
|
An IAttachment80 representing the attachment behavior of the 3D viewshed. |
|
|
Gets and sets the distance, in meters, between the viewshed analysis and the viewer. |
|
|
Gets and sets the horizontal angle limits, in degrees, of the viewshed. |
|
|
Gets and sets the vertical angle limits, in degrees, of the viewshed. |
|
|
An IColor80 representing the fill color of the areas that are not visible from the viewpoint. |
|
|
Gets the ID of the object. (Inherited from ITerraExplorerObject80) |
|
|
An IMessageObject80 representing the message object assigned to the object. |
|
|
Gets an enum that identifies the type of the object representing the viewshed on the terrain. (Inherited from ITerraExplorerObject80) |
|
|
An IPosition80 that defines the position and orientation of the viewshed on the terrain, as well as the distance from which it is viewed when flying to it (or circling it, for example). |

|
|
Gets and sets a Boolean that determines whether the viewshed is saved in the Fly file. (Inherited from ITerraExplorerObject80) |
|
|
An ITerrainObject80 representing terrain properties including draw order and ground object status. Note: The Terrain.Tint property does not apply to 3D viewsheds. |
|
|
An ITimeSpan80 |
|
|
An ITooltip80 representing the tooltip that displays when a mouse cursor is placed over the 3D viewshed in the 3D Window. |
|
|
An ITreeItem80 representing details about the representation of the viewshed in the Project Tree. |
|
|
An IVisibility80 |
|
|
An IColor80 representing the fill color of the areas that are visible from the viewpoint. |
|
|

Distance
Gets and sets the distance of the viewshed analysis from the viewer in meters.
