How To Change The View Point Of A Surf Plot In Matlba
Viewpoint specification
Syntax
-
view(az,el) view([az,el]) view([x,y,z]) view(2) view(3) view(T) [az,el] = view T = view
Description
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 infinite.
view(az,el) and view([az,el]) ready the viewing bending for a three-dimensional plot. The azimuth, az, is the horizontal rotation virtually the z-axis as measured in degrees from the negative y-axis. Positive values bespeak counterclockwise rotation of the viewpoint. el is the vertical peak of the viewpoint in degrees. Positive values of height correspond to moving to a higher place 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 = xc.
view(iii) 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 iv-by-4 matrix such equally a perspective transformation generated by viewmtx.
[az,el] = view returns the electric current azimuth and superlative.
T = view returns the current 4-past-4 transformation matrix.
Remarks
Azimuth is a polar angle in the ten - y plane, with positive angles indicating counterclockwise rotation of the viewpoint. Pinnacle is the angle above (positive angle) or beneath (negative angle) the x - y plane.
This diagram illustrates the coordinate arrangement. The arrows indicate positive directions.
Examples
View the object from directly overhead.
-
az = 0; el = xc; view(az, el);
Set the view along the y -axis, with the x -centrality extending horizontally and the z -axis extending vertically in the figure.
-
view([0 0]);
Rotate the view about the z -axis by 180ยบ.
-
az = 180; el = 90; view(az, el);
