Detailed Description

This interface describes a particular camera view as a focus point on the earth and orientation of the camera view relative to that focus point.

Note:

Modifying one or more properties of an ICameraInfoGE will not change the current camera in Google Earth. You need to call IApplicationGE::SetCamera to change the current camera in the Google Earth application.

Property Documentation

double ICameraInfoGE::FocusPointLatitude [get, set]

Latitude of the focus point on the Earth in degrees.

Valid values range between -90 (South Pole) and 90 (North Pole).

See also:

FocusPointLongitude

double ICameraInfoGE::FocusPointLongitude [get, set]

Longitude of focus point on the Earth in degrees.

Valid values range between -180 and 180, 0 being the longitude of the Prime Meridian.

See also:

FocusPointLatitude

double ICameraInfoGE::FocusPointAltitude [get, set]

Altitude of focus point in meters in respect to altitude mode's reference origin.

The altitude's reference origin is defined by the FocusPointAltitudeMode.

See also:

FocusPointAltitudeMode

AltitudeModeGE ICameraInfoGE::FocusPointAltitudeMode [get, set]

Camera's altitude mode.

Defines the altitude's reference origin for the focus point.

See also:

AltitudeModeGE, FocusPointAltitude

double ICameraInfoGE::Range [get, set]

Distance between camera and focus point in meters.

Valid values are positive.

This is how far the camera is from focus point. The orientation of the camera in respect ot the focus point is given by Tilt and Azimuth.

See also:

Tilt, Azimuth

double ICameraInfoGE::Tilt [get, set]

Camera's tilt angle in degrees.

Valid values are between 0 and 90.

A tilt angle of 0 means the camera is directly on top of the focus point and looking straight down. A tilt angle of 90 degrees means the camera would be looking horizontally towards the focus point. In many cases, however, setting such a high tilt angle is not possible because it would cause the camera to collide with terrain.

See also:

Range, Azimuth

double ICameraInfoGE::Azimuth [get, set]

Camera's azimuth in degrees.

Valid values are between -180 and 180.

An azimuth of 0 means the North Pole is towards the top of the screen for that particular camera, i.e. the camera is looking "towards" the North Pole. An azimuth of 180 means the camera is looking towards the South Pole.
