view
Viewpoint specificationview(az,el) view([az,el]) view([x,y,z]) view(2) view(3) view(T) [az,el] = view T = viewThe 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.
view([x,y,z])
sets the viewpoint to the Cartesian coordinates x
, y
, and z
. The magnitude of (x,y,z)
is ignored.
view(2)
sets the default two-dimensional view, az = 0,
el = 90
.
view(3)
sets the default three-dimensional view, az = --37.5,
el = 30
.
view(T)
sets the view according to the transformation matrix T
, which is a 4-by-4 matrix such as a perspective transformation generated by viewmtx
.
[az,el] = view
returns the current azimuth and elevation.
T = view
returns the current 4-by-4 transformation matrix.
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:az = 0;
el = 90
; view(az, el);
view([0 0]);Rotate the view about the z-axis by 180º:
az = 180
;el = 90
; view(az, el);
