|MATLAB Function Reference|
The position of the viewer (the viewpoint) determines the orientation of the axes. You specify the viewpoint in terms of azimuth and elevation, or by a point in three-dimensional space.
view(az,el) and view([az,el])
set the viewing angle for a three-dimensional plot. The azimuth,
az, is the horizontal rotation about the z-axis as measured in degrees from the negative y-axis. Positive values indicate counterclockwise rotation of the viewpoint.
el is the vertical elevation of the viewpoint in degrees. Positive values of elevation correspond to moving above the object; negative values correspond to moving below the object.
sets the viewpoint to the Cartesian coordinates
z. The magnitude of
(x,y,z) is ignored.
sets the default two-dimensional view,
az = 0,
el = 90.
sets the default three-dimensional view,
az = -37.5,
el = 30.
sets the view according to the transformation matrix
T, which is a 4-by-4 matrix such as a perspective transformation generated by
[az,el] = view
returns the current azimuth and elevation.
T = view
returns the current 4-by-4 transformation matrix.
Azimuth is a polar angle in the x-y plane, with positive angles indicating counterclockwise rotation of the viewpoint. Elevation is the angle above (positive angle) or below (negative angle) the x-y plane.
This diagram illustrates the coordinate system. The arrows indicate positive directions.
View the object from directly overhead.
Set the view along the y-axis, with the x-axis extending horizontally and the z-axis extending vertically in the figure.
Rotate the view about the z-axis by 180º.
