camroll

Set or get roll angle of camera for satellite scenario viewer

Description

camroll(viewer,roll) sets the roll angle of the camera for the satellite scenario viewer. Setting the roll angle rotates the camera around its x-axis.

Camera with double-headed arrow around lens

outRoll = camroll(viewer,___) returns the roll angle of the camera. If the second input is roll, then the function sets the output equal to the input roll.

Input Arguments

collapse all

Satellite scenario viewer, specified as a satelliteScenarioViewer object. viewer must be specified as a scalar satelliteScenarioViewer object.[1]

Roll angle of the camera, specified as a scalar in the range [–360, 360] degrees.

Tips

  • When the pitch angle is near –90 (the default value) or 90 degrees, the camera loses one rotational degree of freedom. As a result, when you change the roll angle, the heading angle might change instead. This phenomenon is called gimbal lock. To avoid the effects of gimbal lock, call the camheading function instead of the camroll function.
