# vispy.scene.cameras.turntable module

class vispy.scene.cameras.turntable.TurntableCamera(fov=45.0, elevation=30.0, azimuth=30.0, roll=0.0, distance=None, translate_speed=1.0, **kwargs)

  Bases: `Base3DRotationCamera`

  3D camera class that orbits around a center point while maintaining a view on a center point.

  For this camera, the `scale_factor` indicates the zoom level, and the `center` indicates the position to put at the center of the view.

  When `elevation` and `azimuth` are set to 0, the camera points along the +y axis.

  Parameters:
    fov float

      Field of view. 0.0 means orthographic projection, default is 45.0 (some perspective)

    elevation float

      Elevation angle in degrees. The elevation angle represents a rotation of the camera around the current scene x-axis. The camera points along the x-y plane when the angle is 0.

    azimuth float

      Azimuth angle in degrees. The azimuth angle represents a rotation of the camera around the scene z-axis according to the right-hand screw rule. The camera points along the y-z plane when the angle is 0.

    roll float

      Roll angle in degrees. The roll angle represents a rotation of the camera around the current scene y-axis.

    distance float | None

      The distance of the camera from the rotation point (only makes sense if fov > 0). If None (default) the distance is determined from the scale_factor and fov.

    translate_speed float

      Scale factor on translation speed when moving the camera center point.

    **kwargs dict

      Keyword arguments to pass to BaseCamera.

  Notes

  Interaction:

  > - LMB: orbits the view around its center point.

  > - RMB or scroll: change scale_factor (i.e. zoom level)

  > - SHIFT + LMB: translate the center point

  > - SHIFT + RMB: change FOV

  property azimuth

    Get the camera azimuth angle in degrees.

    The camera points along the y-z plane when the angle is 0.

  property elevation

    Get the camera elevation angle in degrees.

    The camera points along the x-y plane when the angle is 0.

  orbit(azim, elev)

    Orbits the camera around the center position.

    Parameters:
      azim float

        Angle in degrees to rotate horizontally around the center point.

      elev float

        Angle in degrees to rotate vertically around the center point.

  property roll

    Get the camera roll angle in degrees.
