Syntax

position = campos(viewer)
campos(viewer,lat,lon)
campos(viewer,lat,lon,alt)
campos(viewer,lla)

Description

position = campos(viewer) returns the current position of the camera in the tracking globe viewer.

campos(viewer,lat,lon) sets the latitude and longitude of the camera in the tracking globe viewer.

campos(viewer,lat,lon,alt) additionally sets the altitude of the camera in the tracking globe viewer.

campos(viewer,lla) sets the latitude, longitude, and altitude of the camera in the tracking globe viewer using a vector of geodetic coordinates.

Open Live Script

Create a tracking globe viewer.

viewer = trackingGlobeViewer;

Change the camera position to Boston, Massachusetts.

pos = [42.33598 -71.03103 1.5e4];
campos(viewer,pos);

Take a snapshot and show the results.

snapshot(viewer)

Figure contains an axes object. The axes object contains an object of type image.

Input Arguments

Tracking globe viewer, specified as a trackingGlobeViewer object.1

Latitude of the camera, in degrees, specified as a scalar in the range [-90 90].

Data Types: single | double

Longitude of the camera, in degrees, specified as a scalar in the range [-360 360].

Data Types: single | double

Altitude of the camera above the WGS84 Earth model, in meters, specified as a scalar.

Data Types: single | double

Geodetic coordinates of the camera, specified as a real-valued three-element vector [lat lon alt], where:
