campos - Set or query camera position

Syntax

campos
campos([camera_position])
campos('mode')
campos('auto')
campos('manual')
campos(axes_handle,...)

Description

campos with no arguments returns the camera position in the current axes.

campos([camera_position]) sets the position of the camera in the current axes to the specified value. Specify the position as a three-element vector containing the x-, y-, and z-coordinates of the desired location in the data units of the axes.

campos('mode') returns the value of the camera position mode, which can be either auto (the default) or manual.

campos('auto') sets the camera position mode to auto.

campos('manual') sets the camera position mode to manual.

campos(axes_handle,...) performs the set or query on the axes identified by the first argument, axes_handle. When you do not specify an axes handle, campos operates on the current axes.

Remarks

campos sets or queries values of the axes CameraPosition and CameraPositionMode properties. The camera position is the point in the Cartesian coordinate system of the axes from which you view the scene.

Examples

This example moves the camera along the x-axis in a series of steps:

surf(peaks)
axis vis3d off
for x = -200:5:200
    campos([x,5,10])
    drawnow
end
